TephaFLEX® Surgical Mesh is intended wherever temporary wound support is required, to reinforce soft tissues where weakness exists or for the repair of hernia or other fascial defects that require the addition of a reinforcing or bridging material to obtain the desired surgical result. This includes, but is not limited to the following procedures: vaginal prolapse repair, colon and rectal prolapse repair, reconstruction of the pelvic floor and sacral colposuspension.

The provided document, K070894, describes information about the TephaFLEX® Surgical Mesh. However, it does not contain the type of study information (e.g., about AI/algorithm performance, ground truth, expert review) you're asking for. This document is a 510(k) premarket notification summary, which focuses on demonstrating substantial equivalence to predicate devices, primarily through physical testing and comparison of material properties, rather than clinical efficacy or AI-driven performance metrics.
Therefore, I cannot extract the requested information from this document. The sections you've asked for (acceptance criteria, device performance, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, training set size, and training set ground truth establishment) are typical for AI/ML device submissions, which are not applicable to the TephaFLEX® Surgical Mesh described in K070894.
The document states:
- Safety and Performance: "Physical testing was performed on the TephaFLEX® surgical mesh which determined the TephaFLEX mesh to be substantially equivalent to the mechanical strengths of the predicate devices under indication for use conditions."
- Conclusion: "Based on the indications for use, technological characteristics, and safety and performance testing, the TephaFLEX® Surgical Mesh has been shown to be substantially equivalent to predicate devices..."
This indicates that the "study" was primarily physical testing demonstrating mechanical equivalence, not a clinical study involving human or AI performance data.

Trade/Device Name: TephaFLEX® Surgical Mesh Regulation Number: 21 CFR 878.3300 Regulation Name: Surgical mesh Regulatory Class: II Product Code: FTL Dated: March 29, 2007 Received: March 30, 2007
Dear Ms. LeGraw:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
