AI/ML Overview

The provided documents are a 510(k) summary for the T-Scientific T-Pad™. This type of submission is for demonstrating substantial equivalence to a predicate device, not for proving a device meets specific acceptance criteria based on a clinical study with detailed performance metrics.

Therefore, the documents do not contain the requested information regarding acceptance criteria, study details, sample sizes, ground truth establishment, or expert involvement. The 510(k) summary focuses on demonstrating that the T-Pad™ is technologically equivalent and has the same intended use as its predicate devices (Marine Polymer Technologies' Syvek Patch, K972914 and K984177).

Specifically, the document states:

• "The T-Scientific T-Pad™ technological characteristics are the same as the Marine Polymer Technologies predicate devices. The T-Scientific T-Pad™ works in the same manner as the approved predicate devices."

This indicates that the main "proof" of meeting performance expectations is through demonstrating equivalent technology and mechanism of action to already approved devices. There is no mention of a de novo study with acceptance criteria and performance results for the T-Pad™ itself.

Dear Mr. Metcalf:

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 A.ct. 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 (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
