Intended Use

PriMatrix is intended for the management of wounds that include:

  • Partial and full thickness wounds
  • Pressure, diabetic, and venous ulcers
  • Second-degree burns
  • Surgical wounds-donor sites/grafts, post-Moh's surgery, post-laser surgery, podiatric, wound dehiscence
  • Trauma wounds-abrasions, lacerations, and skin tears
  • Tunneled/undermined wounds
  • Draining wounds
Device Description

PriMatrix is an acellular dermal tissue matrix. The device is supplied sterile and is provided in sheet form in a variety of sizes to be trimmed by the surgeon to meet the individual patient's needs.

AI/ML Overview

The provided text is a 510(k) premarket notification for a medical device called "PriMatrix Dermal Repair Scaffold." This document describes the device, its intended use, and claims substantial equivalence to previously marketed devices. However, it does not contain information about acceptance criteria, a specific study proving the device meets these criteria, or any details related to AI/algorithm performance. Therefore, I cannot extract the requested information regarding AI device evaluation.

The relevant sections of the input text for medical device regulation are highlighted below, but they do not pertain to the performance evaluation of an AI-powered device.

Device Information:

  • Proprietary name: PriMatrix Dermal Repair Scaffold
  • Common name: Animal-derived, dermal extracellular matrix wound care product
  • Classification: Unclassified
  • Intended Use: Management of various types of wounds (partial and full thickness, pressure, diabetic, and venous ulcers, second-degree burns, surgical wounds, trauma wounds, tunneled/undermined wounds, draining wounds).

Substantial Equivalence:

The device claims substantial equivalence to:

  • PriMatrix (TEI Biosciences, K083440)
  • DressSkin (TEI Biosciences, K023778)

Summary of Technological Characteristics and Biocompatibility:

  • PriMatrix is an acellular dermal tissue matrix.
  • It is described as substantially equivalent to other wound care products in design and application.
  • Biocompatibility was assessed through tests including cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, genotoxicity, hemolysis, and pyrogenicity.
  • Manufacturing methods were tested for viral inactivation.

The document focuses on regulatory approval based on substantial equivalence to existing devices and biocompatibility, not on the performance evaluation of a new AI algorithm.

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 10 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 docs 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 of medical device-related adverse events) (21 CFR 803); 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.
