[Docket No. FDA-2019-N-1250]
General and Plastic Surgery Devices; Reclassification of Certain
Surgical Staplers
AGENCY: Food and Drug Administration, HHS.
ACTION: Proposed order.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA or the Agency) is
proposing to reclassify surgical staplers for internal use (currently
regulated under the classification for ``manual surgical instrument for
general use'' and assigned the product code GAG) from class I (general
controls) into class II (special controls) and subject to premarket
review. FDA is identifying the proposed special controls for surgical
staplers for internal use that the Agency believes are necessary to
provide a reasonable assurance of the safety and effectiveness of the
device. FDA is proposing this reclassification on its own initiative
based on new information. As part of this reclassification, FDA is also
proposing to amend the existing classification for ``manual surgical
instrument for general use'' to remove staplers and to create a
separate classification regulation for surgical staplers that
distinguishes between surgical staplers for internal use and external
use.

SUPPLEMENTARY INFORMATION:
I. Background--Regulatory Authorities
The Federal Food, Drug, and Cosmetic Act (FD&C Act), as amended,
establishes a comprehensive system for the regulation of medical
devices intended for human use. Section 513 of the FD&C Act (21 U.S.C.
360c) established three categories (classes) of devices, reflecting the
regulatory controls needed to
[[Page 17117]]
provide reasonable assurance of their safety and effectiveness. The
three categories of devices are class I (general controls), class II
(special controls), and class III (premarket approval).
Section 513(a)(1) of the FD&C Act defines the three classes of
devices. Class I devices are those devices for which the general
controls of the FD&C Act (controls authorized by or under section 501,
502, 510, 516, 518, 519, or 520 (21 U.S.C. 351, 352, 360, 360f, 360h,
360i, or 360j) or any combination of such sections) are sufficient to
provide reasonable assurance of safety and effectiveness; or those
devices for which insufficient information exists to determine that
general controls are sufficient to provide reasonable assurance of
safety and effectiveness or to establish special controls to provide
such assurance, but because the devices are not purported or
represented to be for a use in supporting or sustaining human life or
for a use which is of substantial importance in preventing impairment
of human health, and do not present a potential unreasonable risk of
illness or injury, are to be regulated by general controls (section
513(a)(1)(A) of the FD&C Act). Class II devices are those devices for
which general controls by themselves are insufficient to provide
reasonable assurance of safety and effectiveness, and for which there
is sufficient information to establish special controls to provide such
assurance, including the promulgation of performance standards,
postmarket surveillance, patient registries, development and
dissemination of guidelines, recommendations, and other appropriate
actions the Agency deems necessary to provide such assurance (section
513(a)(1)(B) of the FD&C Act). Class III devices are those devices for
which insufficient information exists to determine that general
controls and special controls would provide a reasonable assurance of
safety and effectiveness, and which are purported or represented to be
for a use in supporting or sustaining human life or for a use which is
of substantial importance in preventing impairment of human health, or
which present a potential unreasonable risk of illness or injury
(section 513(a)(1)(C) of the FD&C Act).
Under section 513(d)(1) of the FD&C Act, devices that were in
commercial distribution before the enactment of the 1976 amendments
(Medical Device Amendments of 1976, Pub. L. 94-295), May 28, 1976
(generally referred to as ``preamendments devices''), are classified
after FDA has: (1) Received a recommendation from a device
classification panel (an FDA advisory committee); (2) published the
panel's recommendation for comment, along with a proposed regulation
classifying the device; and (3) published a final regulation
classifying the device. FDA has classified most preamendments devices
under these procedures.
Devices that were not in commercial distribution before May 28,
1976 (generally referred to as ``postamendments devices''), are
automatically classified by section 513(f)(1) of the FD&C Act into
class III without any FDA rulemaking process. Those devices remain in
class III and require premarket approval, unless, and until: (1) FDA
reclassifies the device into class I or II or (2) FDA issues an order
finding the device to be substantially equivalent, in accordance with
section 513(i) of the FD&C Act, to a predicate device that does not
require premarket approval. The Agency determines whether new devices
are substantially equivalent to previously marketed devices by means of
premarket notification procedures in section 510(k) of the FD&C Act and
part 807, subpart E of the regulations (21 CFR part 807).
On July 9, 2012, Congress enacted the Food and Drug Administration
Safety and Innovation Act (FDASIA) (Pub. L. 112-144). Section 608(a) of
FDASIA amended section 513(e) of the FD&C Act, changing the process for
reclassifying a device from rulemaking to an administrative order.
Section 513(e)(1)(A)(i) of the FD&C Act sets forth the process for
issuing a final order. Specifically, prior to the issuance of an
administrative order reclassifying a device, the following must occur:
(1) Publication of a proposed reclassification order in the Federal
Register, (2) a meeting of a device classification panel described in
section 513(b) of the FD&C Act, and (3) consideration of comments to a
public docket. The proposed reclassification order must set forth the
proposed reclassification and a substantive summary of the valid
scientific evidence concerning the proposed reclassification, including
the public health benefits of the use of the device, and the nature and
incidence (if known) of the risks of the device.
Section 513(e)(1)(A)(i) provides that FDA may, by administrative
order, reclassify a device based on ``new information.'' FDA can
initiate a reclassification under section 513(e) or an interested
person may petition FDA. The term ``new information,'' as used in
section 513(e) of the FD&C Act, includes information developed as a
result of a reevaluation of the data before the Agency when the device
was originally classified, as well as information not presented, not
available, or not developed at that time. (See, e.g., Holland-Rantos v.
United States Dep't of Health, Educ. & Welfare, 587 F.2d 1173, 1174 n.1
(D.C. Cir. 1978); Upjohn Co. v. Finch, 422 F.2d 944 (6th Cir. 1970);
Bell v. Goddard, 366 F.2d 177 (7th Cir. 1966).)
Reevaluation of the data previously before the Agency is an
appropriate basis for subsequent regulatory action where the
reevaluation is made in light of newly available regulatory authority
(see Bell v. Goddard, 366 F.2d 177, 181 (7th Cir. 1966)) or in light of
changes in ``medical science'' (see Upjohn Co. v. Finch, 422 F.2d 944,
951 (6th Cir. 1970)). Whether data before the Agency are old or new,
the ``new information'' to support reclassification under section
513(e) of the FD&C Act must be ``valid scientific evidence'', as
defined in section 513(a)(3) of the FD&C Act and 21 CFR 860.7(c)(2).
(See, e.g., General Medical Co. v. FDA, 770 F.2d 214 (D.C. Cir. 1985);
Contact Lens Mfrs. Assoc. v. FDA, 766 F.2d 592 (D.C. Cir.1985), cert.
denied, 474 U.S. 1062 (1986)).
FDA relies upon ``valid scientific evidence'' in the classification
process to determine the level of regulation for devices. To be
considered in the reclassification process, the ``valid scientific
evidence'' upon which the Agency relies must be publicly available.
Publicly available information excludes trade secret and/or
confidential commercial information, e.g., the contents of a pending
premarket approval application (see section 520(c) of the FD&C Act).
Section 510(m) of the FD&C Act provides that a class II device may
be exempted from the premarket notification requirements under section
510(k) of the FD&C Act if the Agency determines that premarket
notification is not necessary to assure the safety and effectiveness of
the device. FDA has determined that premarket notification is necessary
to reasonably assure the safety and effectiveness of surgical staplers
for internal use. Therefore, the Agency does not intend to exempt this
proposed class II device from premarket notification (510(k))
submission as provided under section 510(m) of the FD&C Act.
II. Regulatory History of the Devices
Surgical staplers were classified in part 878 (21 CFR part 878) in
a final rule published in the Federal Register on June 24, 1988 (53 FR
23856), that classified 51 general and plastic surgery devices. This
1988 rule classified staplers into class I (general controls).
[[Page 17118]]
These devices were grouped with other devices under ``Manual surgical
instrument for general use'' in Sec. 878.4800 (21 CFR 878.4800). At
the time, surgical staplers had been in common use in medical practice
for many years, and FDA believed that general controls were sufficient
to provide reasonable assurance of the safety and effectiveness of
those devices. This rule was amended on April 5, 1989 (54 FR 13826), to
clarify that manual surgical instruments for general use, Sec.
878.4800, made of the same materials as used in the preamendments
devices were exempt from premarket notification (510(k)) review.
On December 7, 1994, FDA further amended the classification when it
published a final rule in the Federal Register (59 FR 63005) that
exempted 148 class I devices from premarket notification, with
limitations. Surgical staplers were one of those exempted devices. FDA
determined that manufacturers' submissions of premarket notifications
were unnecessary for the protection of the public health and that FDA's
review of such submissions would not advance its public health mission.
On March 8, 2019, FDA issued a letter to healthcare providers to
inform them of the risks associated with misuse of surgical staplers
and to provide recommendations for reducing the risk of adverse events
associated with these devices (Ref. 1). This letter recommends that
users carefully follow the stapler manufacturer's instructions for use
and provides additional recommendations for selecting the appropriate
staple sizes and tissue types appropriate for use with the stapler.
Elsewhere in this issue of the Federal Register, FDA is publishing
a notice of availability for a draft guidance entitled ``Surgical
Staplers and Staples for Internal Use--Labeling Recommendations; Draft
Guidance for Industry and Food and Drug Administration Staff.'' As
identified in this draft guidance, FDA has become aware of a large
number of adverse events associated with surgical staplers and staples
for internal use. This draft guidance communicates FDA's
recommendations for contraindications, warnings, directions for use,
and technical characteristics and performance parameters to be included
in the product labeling to help promote the safe and effective use of
surgical staplers and staples for internal use. This draft guidance
also provides recommendations for content to be included in the package
labels, so that users may easily look at the label and obtain critical
information necessary for proper device selection.
Surgical staples are currently regulated as class II devices under
21 CFR 878.4750 (Implantable staple) and are subject to premarket
notification (510(k)) review. FDA does not intend to change the
classification of surgical staples at this time and they are outside
the scope of this reclassification action.
III. Device Description
A surgical stapler is a specialized prescription device used to
deliver compatible staples during surgery. Prescription devices are
exempt from the requirement for adequate directions for use for the
layperson under section 502(f)(1) of the FD&C Act and 21 CFR 801.5, as
long as the conditions of 21 CFR 801.109 are met.
To delineate between surgical staplers and their intended uses, FDA
has identified two subsets of surgical staplers: (1) Surgical staplers
for internal use and (2) surgical staplers for external use.
A surgical stapler for internal use is a specialized prescription
device used to deliver compatible staples to internal tissues during
surgery for removing part of an organ (i.e., resection), cutting
through organs and tissues (i.e., transection), and creating
connections between structures (i.e., anastomoses). It may be used in
open, minimally invasive, and endoscopic surgery. Surgical staplers for
internal use may be indicated for use in a wide range of surgical
applications, including, but not limited to, gastrointestinal,
gynecologic, and thoracic surgery.
Many types of surgical staplers for internal use exist, including,
but not limited to, linear non-cutting staplers, transverse
approximating staplers, transverse anastomoses staplers,
gastrointestinal anastomoses linear cutting (articulating and non-
articulating) staplers, and circular (i.e., end-to-end anastomoses)
staplers. Surgical staplers for internal use include both manual and
powered staplers.
A surgical stapler for external use is a specialized prescription
device used to deliver compatible staples to skin during surgery. FDA
is proposing to reclassify internal staplers only; external staplers
will remain class I, exempt from premarket review.
IV. Proposed Reclassification
FDA is proposing to reclassify surgical staplers for internal use
from class I (general controls), exempt from premarket review, to class
II (special controls), subject to premarket review. FDA believes that
general controls by themselves are insufficient to provide reasonable
assurance of safety and effectiveness for these devices, and that there
is sufficient information to establish special controls to provide such
assurance. In accordance with section 513(e)(1)(A)(i) of the FD&C Act,
FDA, on its own initiative, is proposing to reclassify these devices
based on new information. The process for issuing a final order for
reclassification of a device from class I to class II pursuant to
section 513(e) of the FD&C Act is provided in 21 CFR 860.130 of the
regulations. Specifically, prior to the issuance of a final order
reclassifying a device, the following must occur: (1) Publication of a
proposed reclassification order in the Federal Register; (2) a meeting
of a device classification panel described in section 513(b) of the
FD&C Act; and (3) consideration of comments to a public docket. The
Commissioner of Food and Drugs is required to consult with a
classification panel and may secure a recommendation with respect to
the reclassification of the device. FDA will consult with the panel
regarding the reclassification of the device in accordance with the
procedures set forth in 21 CFR 860.125 and intends to secure the
panel's recommendation. If FDA issues a final order, the Agency will
publish the panel's recommendation in the Federal Register when the
Agency publishes the final order.
FDA is also proposing to revise Sec. 878.4800 (Manual surgical
instrument for general use) to remove staplers and to create a separate
classification regulation in part 878 for surgical staplers that
distinguishes between surgical staplers for internal use and external
use.
V. Public Health Benefits and Risks to Health
As required by section 513(e)(1)(A)(i) of the FD&C Act, FDA is
providing a substantive summary of the valid scientific evidence
concerning the proposed reclassification including the public health
benefit of the use of surgical staplers for internal use, and the
nature, and if known, the incidence of the risk of the devices, as
discussed in section VI of this proposed order.
Surgical staplers for internal use provide benefit to the public
health by facilitating surgical procedures and allowing for shorter
surgical procedure times compared to manual suturing.
FDA has evaluated the risks to health associated with the use of
surgical staplers for internal use and has identified the following
risks for this device:
[[Page 17119]]
Complications associated with device failure/malfunction.
Device failures or malfunctions may result in prolonged surgical
procedures, unplanned surgical interventions, and other complications
such as bleeding, sepsis, fistula formation, tearing of internal
tissues and organs, increased risk of cancer recurrence, and death.
Complications associated with use error/improper device
selection and use. Use error may result from a device design that is
difficult to operate and/or labeling that is difficult to comprehend.
For example, user difficulty in firing the stapler may result in
staples not being fully deployed, and misfiring may result in staples
being inadvertently applied to the wrong tissue. Inadequate
instructions for use may result in selection of incorrectly sized
staples for the target tissue. When staples are applied to the wrong
tissue or when incorrectly sized staples are applied, staples are
unable to properly approximate the underlying tissue, resulting in
tissue damage, anastomotic leakage, and bleeding. This in turn, may
lead to more severe complications, such as abscess, sepsis,
peritonitis, hemorrhage, or death.
Adverse tissue reaction. If the patient-contacting
materials of the device are not biocompatible, local tissue irritation
and sensitization, cytotoxicity, or systemic toxicity may occur when
the device contacts sterile tissue.
Infection. If the device is not adequately reprocessed or
sterilized, the device may introduce pathogenic organisms into sterile
tissue and may cause an infection in a patient.
As discussed further in this document, these findings regarding the
public health benefits and risks to health associated with surgical
staplers for internal use are based on publicly available information,
including Medical Device Reporting (MDR) analyses, recalls, and the
published literature.
VI. Summary of Data Upon Which the Reclassification Is Based
Surgical staplers for internal use have been shown to provide
several benefits over manual suturing, including reduction in surgical
time, reduced tissue trauma/manipulation, reduction in surgical
contamination by intestinal contents, and simple closure of vessels
and/or tissues (Ref. 2); however, they have also been associated with
numerous adverse events.
As discussed below, based on a review of the MDR database, recalls
database, and the published scientific literature, there have been many
malfunctions and other problems associated with surgical staplers for
internal use, and some of these malfunctions or other problems have
been associated with serious complications, including death.
Because surgical staplers are used together with staples as a
system, a search of the MDR database was conducted for both surgical
staplers for internal use under product code GAG (Stapler, Surgical)
and surgical staples for internal use under product code GDW (Staple,
Implantable) to obtain a comprehensive picture of the safety profile
for surgical staplers for internal use. From January 1, 2011, to March
31, 2018, FDA received over 41,000 individual MDRs for surgical
staplers and staples for internal use, including 366 deaths, over 9,000
serious injuries, and over 32,000 malfunctions. Some of the most
commonly reported problems in these adverse event reports include an
opening of the staple line or malformation of staples, misfiring,
difficulty in firing, failure of the stapler to fire the staple, and
misapplied staples (e.g., user applying staples to the wrong tissue or
applying staples of the wrong size to tissue). Although the majority of
the adverse events were reported under product code GDW, FDA believes
that many of the problems identified in these reports can be primarily
attributed to surgical staplers for internal use, since proper staple
formation is largely contingent on proper function and use of the
stapler.
Of the 366 deaths, the cause of death was associated with an
opening of the staple line or malformation of staples in 159 reports,
bleeding during surgery in 53 reports, sepsis in 47 reports,
peritonitis in 5 reports, necrosis in 5 reports, and air embolism in 4
reports. Additionally, of the 366 deaths, 195 reports included
misfiring, difficulty in firing, and/or misapplied staples. Common
reasons cited for these problems included mechanical issues with the
device (e.g., mechanical jams), broken device components, and the
device operating differently than the user expected (e.g., different
force needed to deploy the device than expected). In 11 of the 366
deaths, use error was determined to be a contributing factor to the
death. Many of the same complications that resulted in death (e.g.,
bleeding during surgery, peritonitis, and sepsis) were also reported in
the serious injury reports; additional complications commonly reported
in the serious injury reports included tissue damage, organ perforation
or dehiscence, fistula formation, infection, hernia, and pain.
The majority of staplers reported in these adverse events were
linear staplers, including articulating and curved tip linear staplers,
followed by circular staplers. Of the 366 deaths, 262 deaths were
reported for linear staplers while 63 were reported for circular
staplers; of the remaining 41 deaths, a type of stapler was not
identified in the MDR. The staplers involved in these adverse events
spanned a variety of different manufacturers; there were no distinct
differences between manufacturers and the reported causes of death.
Of the 41,000 individual MDRs, over 32,000 MDRs were received for
malfunctions, under either the product code GAG (Stapler, Surgical) or
product code GDW (Staple, Implantable). The most common device-related
malfunctions included failure of the stapler to fire the staple,
failure to form staples, difficulty of opening/closing the stapler,
stapler misfiring, and stapler breakage. The most commonly reported
patient consequences from malfunctions with surgical staplers for
internal use included a delay in surgical procedure, hemorrhage, and
tissue damage. It should be noted that some patient consequences may
not be limited to a single reporting category of death, serious injury,
or malfunction. For example, a malfunction could result in sepsis,
which could lead to other serious injury and later death.
The types and incidence of malfunctions and clinical consequences
to patients seen in the adverse event reports are also corroborated by
the published literature. In a systematic review of 30 clinical studies
(Refs. 3 to 32), including randomized controlled trials and
observational studies, the occurrence of stapler malfunctions in these
studies ranged from incidents in 0 to 19.2 percent (median = 1.8
percent) of patients and 0.1 to 5.2 percent of deployments.
Consistent with the malfunctions seen in the adverse event reports
received by FDA, the most common malfunctions reported in these
clinical studies were related to opening of the staple line or
malformation of staples. In these studies, malformed staples and/or
staple lines comprised 31.8 percent of the malfunctions, while missing
staples and/or staple lines not forming comprised 19.5 percent of the
malfunctions. Problems with stapler firing and/or stapler function were
also commonly reported. Device sticking, locking, and/or jamming
comprised 15.9 percent of the malfunctions, while stapler misfiring
comprised 10.3 percent of the malfunctions. Inability of the stapler to
cut through tissue comprised
[[Page 17120]]
3.1 percent of the malfunctions, while stapler breakage comprised 2.6
percent of all malfunctions. Finally, problems with the stapler
cartridge not loading properly comprised 2.1 percent of the
malfunctions. Although the majority of studies in the systematic
literature review did not report on the incidence of stapler problems
associated with use error, a prospective, single-arm study evaluating
use of a surgical stapler in gastrointestinal stapling applications
found that 3.5 percent of stapler deployments in the study (15 of 423
deployments) were attributed to use error (Ref. 10). Additionally, as
discussed further below, common causes for surgical complications
reported in the literature include use error.
While 75.8 percent of the stapler malfunctions in these studies did
not result in any major consequences to the patient, 10.5 percent of
the malfunctions resulted in the need to convert to open surgery, while
9.7 percent of the malfunctions resulted in hemorrhage; 4.0 percent of
the malfunctions resulted in both hemorrhage and the need to convert to
open surgery. In addition, multiple studies suggest that surgical
stapler malfunctions are associated with a higher risk of
complications. In a retrospective study of 349 colorectal resections
using a circular stapler, surgeries with surgical stapler malfunctions
were found to have higher incidences of unplanned proximal diversions,
ileus, gastrointestinal bleeding, and blood transfusions (Ref. 27). In
a retrospective study of 1,174 patients undergoing liver transections
using a stapler device, surgeries with surgical stapler malfunctions
were found to have a higher likelihood of transfusion, higher median
blood loss, and higher odds of morbidity and mortality compared to
surgeries without stapler malfunctions (Ref. 28). Anastomotic leaks
from surgical stapler malfunctions have also been associated with an
increased risk of cancer recurrence (Refs. 33 to 35). Altogether, the
adverse event reports and published literature indicate that surgical
stapler malfunctions are not uncommon and may produce adverse outcomes
such as conversion to open surgery, bleeding, morbidity, and death.
Common causes for surgical complications reported in the literature
also include the use of incorrectly sized staples for the tissue,
incorrect use of the device by the user, and improper use of the device
for the condition of the patient's tissues, which may result in
reoperation or prolonged hospitalization (Ref. 36). For example, early
postoperative anastomotic leak due to such device issues may result in
a septic patient with peritonitis, requiring immediate surgery with
diversion of stool into a stoma. Minor or delayed anastomotic leaks due
to such device issues may result in an intra-abdominal abscess
requiring surgical or other invasive drainage procedures, temporary
diversion of stool, and prolonged intravenous nutrition. These
complications commonly result in prolonged hospital stays (Ref. 37).
Altogether, the adverse event reports and published literature indicate
that surgical stapler for internal use use error may cause or
contribute to surgical complications, e.g., anastomotic leaks, abscess,
sepsis, peritonitis, and death.
From November 1, 2002, to December 30, 2018, FDA received a total
of 168 recalls for surgical staplers and staples for internal use under
product codes GAG and GDW, including one class I recall and 167 class
II recalls. The class I recall was for a hemorrhoidal circular stapler
that may result in incomplete staple formation due to difficulty in
firing. Of the 167 class II recalls, the most common reasons for recall
included non-conforming device components or device design-related
issues that may result in incomplete staple formation, failure to form
a staple line, malformed staples, or difficulty in firing. Several
devices were also recalled due to a potential breach in sterility.
FDA acknowledges that the available valid scientific evidence,
including the review of the MDR database, recalls database, and the
published literature, primarily discuss surgical staplers for internal
use, and not surgical staplers for external use. At this time, FDA does
not believe that available information suggests that reclassification
of surgical staplers for external use is necessary to maintain a
reasonable assurance of safety and effectiveness of these devices.
Based on its review of the MDR database, recalls database, and the
published literature, FDA has tentatively determined that special
controls, in addition to general controls, are necessary to provide a
reasonable assurance of safety and effectiveness for surgical staplers
for internal use. FDA believes the establishment of special controls is
necessary to ensure that the risks to health are adequately mitigated
by an assessment of these devices through completion of performance
testing, usability and labeling comprehension testing, biocompatibility
evaluation, sterility and shelf-life testing, and adequate labeling. In
addition, FDA believes that design controls under 21 CFR 820.30 are
necessary to ensure that specified design requirements are met and to
ensure compatibility of surgical staplers for internal use with
staples. Therefore, FDA, on its own initiative, is proposing to
reclassify these devices from class I into class II (special controls)
subject to premarket review.
VII. Summary of Reasons for Reclassification
Based on the information reviewed by FDA, including the valid
scientific evidence regarding the public health benefit and nature and
incidence of the risk of the devices discussed in section VI, FDA
tentatively concludes that special controls, in addition to general
controls, are necessary to provide a reasonable assurance of safety and
effectiveness for surgical staplers for internal use. Therefore, FDA
proposes to reclassify surgical staplers for internal use from class I
into class II (special controls).
VIII. Proposed Special Controls
FDA believes that the following special controls, together with
general controls, are necessary and sufficient to mitigate the risks to
health described in section V (complications associated with device
failure/malfunction, complications associated with use error/improper
device selection and use, adverse tissue reaction, and infection) and
provide a reasonable assurance of safety and effectiveness for surgical
staplers for internal use.
Both device misuse and device malfunctions are root causes of the
adverse events associated with use of surgical staplers for internal
use (Ref. 38). Device misuse may be exacerbated by inadequate
instructions for use and insufficient warnings or precautions in the
device labeling (Ref. 39). To mitigate the risks of tissue damage,
anastomotic leakage, and bleeding arising from use error or improper
device use, FDA believes that the labeling must include specific
instructions for device use, including procedures associated with
proper device use and measures for preventing device malfunction,
evaluating the appropriateness of the target tissue for stapling, and
evaluating the resultant staple line. To further mitigate these risks,
the labeling must also include appropriate warnings, contraindications,
and limitations needed for safe use of the device. To prevent stapler
malfunction (e.g., from stapler jamming, locking, sticking, or
misfiring), information on the staples with which the stapler is
compatible must be provided in the labeling, such as models of
compatible staples, cartridge colors/staple heights, staple rows per
cartridge, staple patterns, and
[[Page 17121]]
maximum and minimum tissue thicknesses for each staple type. To prevent
improper application of staples to target tissue, the recommended
tissues (e.g., tissue thicknesses and tissue types) on which the
stapler is intended to be used must be identified in the labeling.
Unless data demonstrates the safety of doing so, contraindications must
be identified regarding use of the device on tissues for which the risk
of stapling outweighs any reasonably foreseeable benefit due to known
complications, including the stapling of necrotic or ischemic tissues
and tissues outside of the labeled limits of tissue thickness. The
labeling must provide appropriate warnings regarding how to avoid known
hazards associated with device use, including avoidance of obstructions
to the creation of a staple line (e.g., clips) and the unintended
stapling of other anatomic structures; avoidance of clamping and
unclamping of delicate tissue structures (e.g., venous structures and
bile ducts) to prevent tissue damage; avoidance of use of the stapler
on large blood vessels, such as the aorta; establishing and maintaining
proximal control of blood vessels prior to stapling; appropriate
measures to take if a stapler malfunction occurs while applying staples
across a blood vessel, such as clamping or ligating the vessel before
releasing the stapler, while the stapler is still closed on the tissue;
and ensuring stapler compatibility with staples, unless information is
provided demonstrating that the warnings do not apply to a particular
device. Usability testing and a labeling comprehension study must
demonstrate that the clinician can correctly select and use the device
for its indicated use based on the information in the labeling.
To mitigate the risk of complications associated with device
failure or device malfunction, adequate performance testing is needed
to ensure that the stapler with compatible staples performs as intended
under anticipated conditions of use. FDA believes that adequate
performance testing must include an evaluation of staple formation
characteristics in the maximum and minimum tissue thicknesses for each
staple type; measurement of the worst-case deployment pressures on
stapler firing force; and a measurement of staple line strength.
Performance testing must also demonstrate confirmation of staple line
integrity (e.g., through the absence of vertically contiguous malformed
staples), as well as in vivo confirmation of staple line hemostasis
following staple deployment.\1\
---------------------------------------------------------------------------
\1\ FDA supports the principles of the ``3Rs,'' to reduce,
refine, and replace animal use in testing when feasible. FDA
encourages sponsors to consult with FDA if they wish to use a non-
animal testing method they believe is suitable, adequate, validated,
and feasible. FDA will consider if such an alternative method could
be assessed for equivalency to an animal test method.
---------------------------------------------------------------------------
FDA believes that the inclusion of important technical
characteristics and device performance parameters in the labeling will
also help mitigate use error and device malfunctions by informing end
users on device limitations. Therefore, FDA believes that the labeling
must identify key technical characteristics and performance parameters
of the surgical stapler and compatible staples needed for safe use of
the device. Key technical characteristics include stapler
specifications (e.g., jaw length, shaft length, jaw opening, and angles
of articulation), as well as compatible staple specifications (e.g.,
open and closed staple heights). Key technical characteristics also
include identification of any safety mechanisms of the stapler, such as
a color-firing zone and/or lock-out mechanism. Examples of key
performance parameters include information on firing the stapler, such
as the firing force, pre-fire compression time, and maximum number of
consecutive firings, and information relevant to creating a staple
line, such as the percentage of properly formed staples, number of
incremental firings required to complete a staple line, and maximum
number of reloads.
FDA believes that the device must be demonstrated to be
biocompatible because the risk of adverse tissue reaction may result
from contact of the materials of the device with the body.
Additionally, because the risk of infection can arise from a
contaminated device, sterility testing must demonstrate the sterility
of the device. If any components of the device are reusable, the
labeling must include validated methods and instructions for cleaning
and sterilization of these reusable components. Validation of cleaning
and sterilization instructions must demonstrate that any reusable
device components can be safely and effectively reprocessed per the
recommended cleaning and sterilization protocol in the labeling.
In addition, loss of package integrity can result in compromised
sterility and compromised device performance over time. Therefore,
shelf-life testing must demonstrate that the device maintains its
performance characteristics and the packaging of the device maintains
its integrity for the duration of the proposed shelf-life. Finally, the
labeling must also specify an expiration date to inform users of the
shelf-life of the device based on the shelf-life testing.
Table 1 shows how FDA believes each risk to health described in
section V would be mitigated by the proposed special controls.

If finalized, the reclassification of surgical staplers for
internal use into class II would subject these devices to premarket
notification under section 510(k) of the FD&C Act and part 807, subpart
E, and the identified special controls in this order. FDA believes that
the proposed reclassification would provide reasonable assurance of
safety and effectiveness of surgical staplers for internal use.
IX. Analysis of Environmental Impact
The Agency has determined under 21 CFR 25.34(b) that this action is
of a type that does not individually or cumulatively have a significant
effect on the human environment. Therefore, neither an environmental
assessment nor an environmental impact statement is required.
X. Paperwork Reduction Act of 1995
FDA tentatively concludes that this proposed order contains no new
collections of information. Therefore, clearance by the Office of
Management and Budget (OMB) under the Paperwork Reduction Act of 1995
(PRA) (44 U.S.C. 3501-3520) is not required. This proposed order refers
to previously approved collections of information found in FDA
regulations. These collections of information are subject to review by
OMB under the PRA. The collections of information in part 807, subpart
E, have been approved under OMB control number 0910-0120; the
collections of information in 21 CFR part 814, subparts A through E,
have been approved under OMB control number 0910-0231; the collections
of information in 21 CFR part 801 have been approved under OMB control
number 0910-0485; and the collections of information in 21 CFR part 820
have been approved under OMB control number 0910-0073.
XI. Proposed Effective Date
FDA proposes that any final order based on this proposed order
become effective on its date of publication in the Federal Register.
Surgical staplers for internal use that have not been
offered for sale prior to the effective date of the final order or have
been offered for sale but are required to submit a new 510(k) under 21
CFR 807.81(a)(3): Manufacturers would have to obtain 510(k) clearance
before marketing their devices after the effective date of the order.
If a manufacturer markets such a device without receiving 510(k)
clearance, then FDA would consider taking action against such a
manufacturer under its usual enforcement policies.
Surgical staplers for internal use that have been offered
for sale prior to the effective date of the final order and do not
already have 510(k) clearance: FDA does not intend to enforce
compliance with the 510(k) requirement or special controls until 180
days after the effective date of the final order. After that date, if a
manufacturer continues to market such a device but does not have 510(k)
clearance or FDA determines that the device is not substantially
equivalent or not compliant with special controls, then FDA would
consider taking action against such manufacturer under its usual
enforcement policies.
For surgical staplers for internal use that have prior 510(k)
clearance, FDA would accept a new 510(k) and would issue a new
clearance letter, as appropriate, indicating substantial equivalence
and special controls compliance. These devices could serve as
predicates for new devices. These clearance letters would be made
publicly available in FDA's 510(k) database, and compliance with
special controls at the time of clearance would also be stated in the
publicly available 510(k) Summary posted in this database. FDA believes
that our public database is a transparent tool allowing users to
confirm that their devices have been submitted under a new 510(k) and
demonstrated conformance to applicable special controls.
XII. Codification of Orders
Prior to the amendments by FDASIA, section 513(e) of the FD&C Act
provided for FDA to issue regulations to reclassify devices. Although
section 513(e) as amended requires FDA to issue final orders rather
than regulations, it also provides for FDA to revoke previously issued
regulations by order. FDA will continue to codify classifications and
reclassifications in the Code of Federal Regulations (CFR). Changes
resulting from final orders will appear in the CFR as changes to
codified classification determinations or as newly codified orders.
Therefore, under section 513(e)(1)(A)(i), as amended by FDASIA, in the
proposed order, we are proposing to revoke the classification of
surgical staplers in Sec. 878.4800 and to codify surgical staplers in
the new 21 CFR 878.4740, under which surgical staplers for internal use
would be reclassified into class II and surgical staplers for external
use would remain in class I.
