Intended Use

GORE® BIO-A® Tissue Reinforcement is intended for use in the reinforcement of soft tissue. This includes use in patients requiring soft tissue reinforcement in plastic and reconstructive surgery.

Examples of applications where GORE® BIO-A® Tissue Reinforcement may be used include: -Hernia repair as suture line reinforcement -Muscle flap reinforcement -General tissue reconstructions

Device Description

The subject GORE® BIO-A® Tissue Reinforcement is a bioabsorbable web structure that functions as a surgical mesh for soft tissue reinforcement while providing a scaffold for tissue ingrowth. It is used to reinforce soft tissue during the phases of wound healing by filling soft tissue deficits. It elicits a physiologic tissue response which fills the deficit with native tissue and gradually absorbs the device. The implanted GORE® BIO-A® Tissue Reinforcement is a porous, fibrous flat sheet web structure composed solely of synthetic bioabsorbable polyglycolide / trimethylene carbonate copolymer. In vivo studies indicate the bioabsorption process should be complete by six to seven months. The device is available in various sizes and can be trimmed to the desired shape by the surgeon at time of use. The device is sterilized by gamma irradiation validated to an SAL of 10-6. It is for single use only.

AI/ML Overview

The provided document is a 510(k) premarket notification for a medical device called "GORE BIO-A Tissue Reinforcement," which is a surgical mesh. This document does not describe a study involving an AI/Machine Learning device or its acceptance criteria. Instead, it discusses the substantial equivalence of a bioabsorbable surgical mesh to previously marketed predicate devices.

Therefore, I cannot extract the information required to populate the fields related to an AI/Machine Learning device study, such as

  • A table of acceptance criteria and the reported device performance (for an AI/ML device)
  • Sample size used for the test set and data provenance
  • Number of experts used to establish ground truth
  • Adjudication method
  • MRMC comparative effectiveness study results
  • Standalone performance (algorithm only)
  • Type of ground truth used
  • Sample size for the training set
  • How ground truth for the training set was established

The document explicitly states: "No bench or clinical testing was used to support this 510(k) premarket notification. The animal study presented in this submission demonstrated equivalent performance when comparing Gore's synthetic PGA:TMC scaffold to a Cook's SIS collagen-based scaffold structure."

This indicates that the device's substantial equivalence was demonstrated through comparison to predicates and an animal study, not through a performance study against acceptance criteria for an AI/ML algorithm.

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set

reconstructive surgery. Examples of applications where GORE® BIO-A® Tissue Reinforcement may be used include: Hernia repair as suture line reinforcement, Muscle flap reinforcement, and General tissue reconstructions

Differences in Technological Characteristics

The information provided in this premarket notification supports that the difference in material between the subject and predicate mesh devices (synthetic polymer vs. porcine tissue) raises no new issues of safety or effectiveness when used for the expanded indication in patients requiring soft tissue reinforcement in plastic and reconstructive surgery.

Summary of Performance Testing

No bench or clinical testing was used to support this 510(k) premarket notification. The animal study presented in this submission demonstrated equivalent performance when comparing Gore's synthetic PGA:TMC scaffold to a Cook's SIS collagen-based scaffold structure. The two materials performed as intended in an equivalent manner and raised no new questions of safety or effectiveness.

Conclusion

W. L. Gore & Associates concludes that the subject GORE® BIO-A® Tissue Reinforcement device is substantially equivalent to the predicate devices in terms of intended/indications for use, design, materials, function, biocompatibility, and sterilization.
