Intended Use

GORE® SEAMGUARD® Reinforcement is indicated for use in surgical procedures in which soft tissue transection or resection with staple line reinforcement is needed. GORE® SEAMGUARD® Reinforcement can be used for reinforcement of staple lines during hysterectory, liver resection, bladder reconstruction, bronchial, bariatric, colon, colorectal, esophagus, gastric, mesentery, pancreas, small bowel, and spleen procedures. GORE® SEAMGUARD® Reinforcement is also intended to be used for reinforcement of staple lines (i.e., occlusion of the left atrial appendage during open chest procedures) during cardiac surgery.

Device Story

Implantable bioabsorbable reinforcement material; used with surgical staplers to reinforce staple lines during soft tissue transection/resection. Device consists of PGA:TMC material; secured to stapler cartridge/anvil jaws via PLA:TMC adhesive-coated tabs. Modified design utilizes adhesive-coated tabs wrapping around stapler jaws to improve fit across varying stapler surface topographies; replaces previous fully-coated surface attachment method. Used in OR by surgeons; facilitates staple line integrity. Benefits include reduced risk of leaks/bleeding at staple sites. Device is supplied with loading carriers to facilitate attachment to stapler.

Clinical Evidence

No clinical evaluations conducted. Substantial equivalence supported by bench testing (design verification, deployment reliability) and reliance on existing animal study data from the predicate device.

Technological Characteristics

Bioabsorbable PGA:TMC reinforcement material; PLA:TMC adhesive. Attaches to surgical stapler cartridge/anvil jaws via adhesive-coated tabs. Includes loading carriers for deployment. Sterilization method not specified. No software or electronic components.

Indications for Use

Indicated for patients undergoing surgical procedures requiring soft tissue transection or resection where staple line reinforcement is necessary, including hysterectomy, lung/liver resection, bladder reconstruction, bronchial, bariatric, colon, colorectal, esophageal, gastric, mesenteric, pancreatic, small bowel, splenic, and cardiac procedures (left atrial appendage occlusion).

Regulatory Classification

Identification

Dear Ms. Smith:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.

### Predicate Device

- . GORE® SEAMGUARD® Reinforcement K131658
### Device Description

The modified GORE® SEAMGUARD® Reinforcement possesses the same indications for use and fundamental scientific technology as the predicate GORE® SEAMGUARD® Reinforcement. The implantable device and loading carriers of the predicate GORE® SEAMGUARD® Reinforcement are being modified to permit the reinforcement material to be loaded onto the stapler and attach via adhesive-coated tabs that wrap around the side/back of the cartridge/anvil jaws of a surgical stapling device, in lieu of attaching a fully-coated device surface to the top surfaces of the cartridge/anvil jaws, to minimize the impact of the surface topography of surgical staplers in establishing compatible device fit. The implantable materials of the modified GORE® SEAMGUARD® Reinforcement and predicate GORE® SEAMGUARD® Reinforcement are the same bioabsorbable PGA:TMC. Both utilize

{4}------------------------------------------------

## Section 5 - 510(k) Summary

K150551

the same bioabsorbable PLA:TMC adhesive to secure the device onto the iaws of a surqical stapler.

#### Indications for Use

GORE® SEAMGUARD® Reinforcement is indicated for use in surgical procedures in which soft tissue transection or resection with staple line reinforcement is needed. GORE® SEAMGUARD® Reinforcement can be used for reinforcement of staple lines during hysterectomy, lung resection, liver resection, bladder reconstruction, bronchial, bariatric, colon, colorectal, esophagus, gastric, mesentery, pancreas, small bowel, and spleen procedures. GORE® SEAMGUARD® Reinforcement is also intended to be used for reinforcement of staple lines (i.e., occlusion of the left atrial appendage during open chest procedures) during cardiac surgery.

#### Summary of Similarities and Differences in Technological Characteristics

The indications for use for the modified GORE® SEAMGUARD® Reinforcement device is identical to the predicate GORE® SEAMGUARD® Reinforcement device. Both the modified and predicate GORE® SEAMGUARD® Reinforcement devices utilize loading carriers to load the implantable device and the same adhesive to secure the device onto the cartridge/anvil jaws of a compatible stapler. Both devices are comprised of the same bioabsorbable materials. The primary difference between the modified GORE® SEAMGUARD® Reinforcement and predicate GORE® SEAMGUARD® Reinforcement devices is the addition of adhesive-coated tabs for the modified device to permit attachment to a different location on a surgical stapler and a corresponding modification to the geometry of the loading carriers to facilitate attachment of the modified device.

### Performance Data / Predicate Device Comparison

#### Pre-Clinical:

Bench study - Design verification testing of the modified GORE® SEAMGUARD® Reinforcement device consisted of deployment reliability testing under simulated use conditions and same/similar acceptance criteria. The tests demonstrated the performance of the modified GORE® SEAMGUARD® Reinforcement device is substantially equivalent to the predicate GORE® SEAMGUARD® Reinforcement device.

In Vivo (Animal study): No new animal studies were required to demonstrate substantial equivalence of the modified GORE® SEAMGUARD® Reinforcement device to the PREDICATE Seamguard. The animal studies conducted for the predicate GORE® SEAMGUARD® Reinforcement are applicable to the modified GORE® SEAMGUARD® Reinforcement device.

Clinical: No clinical evaluations of this product have been conducted.

## Conclusion

W.L. Gore & Associates concludes that the modified GORE® SEAMGUARD® Reinforcement device is substantially equivalent to the predicate GORE® SEAMGUARD® Reinforcement device in terms of indications for use, design, materials, biocompatibility, packaging, sterilization, labeling, and performance.
