AI/ML Overview

The provided text is a 510(k) Premarket Notification for the PriMatrix Dermal Repair Scaffold. This type of regulatory submission in the US is for devices that are demonstrating substantial equivalence to a legally marketed predicate device, rather than proving safety and effectiveness through clinical trials with specific performance criteria against a disease state or condition.

Therefore, the document does not contain the kind of information requested in your prompt regarding acceptance criteria, device performance metrics, study designs (test sets, training sets, ground truth establishment, expert qualifications, MRMC studies, standalone performance), or statistical results like effect sizes.

Instead, the submission focuses on:

• Device Description: What the device is (acellular dermal tissue matrix).
• Intended Use: The types of wounds it's meant to manage.
• Substantial Equivalence: Claiming similarity in function and intended use to existing devices (PriMatrix K061407 and Oasis K061711).
• Biocompatibility Assessment: Mentioning tests performed (cytotoxicity, sensitization, etc.) to demonstrate safety.
• Manufacturing Methods: Stating that viral inactivation levels were assured.

Consequently, I cannot fill out the requested table or answer the specific questions about acceptance criteria, study details, sample sizes, ground truth, or expert qualifications based on the information provided in this 510(k) summary.

Summary of Technological Characteristics and Biocompatibility

PriMatrix is substantially equivalent to other wound care products with respect to its design and application.

A rigorous biocompatibility assessment performed by an independent certified laboratory demonstrated the biocompatibility of PriMatrix. The tests performed included: cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, genotoxicity, hemolysis, and pyrogenicity. The manufacturing methods for PriMatrix were also tested by an independent laboratory to assure safe levels of viral inactivation.

Dear Dr. James:

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 (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.
