Device Description

BIOBRANE Dressing and BIOBRANE Glove are wound dressings made from an ultrathin, semipermeable, perforated silicone membrane that is mechanically bonded to a flexible knitted tri-filament nylon fabric. Denatured porcine dermal collagen is bonded to the silicone-nylon membrane to provide a flexible and conformable dressing with adherence properties and a hydrophilic surface.

AI/ML Overview

This document is a 510(k) K242146 premarket notification for the BIOBRANE Dressing and BIOBRANE Glove. It asserts substantial equivalence to the predicate device BIOBRANE II (K901369).

Here's an analysis of the provided information relating to acceptance criteria and device performance:

1. Table of Acceptance Criteria and Reported Device Performance

The submission does not provide a table of acceptance criteria with specific performance metrics such as sensitivity, specificity, accuracy, or any quantitative measures for the device's diagnostic or predictive capabilities. This is likely because the device is a wound dressing, not a diagnostic AI/ML device.

Instead, the submission focuses on demonstrating substantial equivalence to a predicate device through shared characteristics and verification tests. The "acceptance criteria" can be inferred as successful completion of these tests and demonstration that the device's characteristics are similar to the predicate.

2. Sample Size Used for the Test Set and Data Provenance

The document explicitly states: "No clinical data is relied upon in this submission to determine substantial equivalence."

Therefore:

  • Sample size for the test set: Not applicable, as no clinical test set was used for substantial equivalence determination.
  • Data provenance: Not applicable. The evaluation was based on non-clinical (bench) testing and comparison of technological characteristics.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

Not applicable, as no clinical test set with a ground truth established by experts was used. The substantial equivalence was based on non-clinical data and direct comparison to a predicate device.

4. Adjudication Method for the Test Set

Not applicable, as no clinical test set was used requiring adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not performed or relied upon. This is a wound dressing, not an AI/ML diagnostic device where such studies are typical.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Not applicable. This device is a wound dressing, not an algorithm or software-only device.

7. The Type of Ground Truth Used

Not applicable, as no clinical data or ground truth in the context of diagnostic performance was used. The "ground truth" for this submission is implicitly the established safety and efficacy profile of the legally marketed predicate device (BIOBRANE II, K901369) and the physical/chemical properties assessed through bench testing.

8. The Sample Size for the Training Set

Not applicable. This is not an AI/ML device that requires a training set.

9. How the Ground Truth for the Training Set Was Established

Not applicable. This is not an AI/ML device that requires a training set or ground truth for training.

Dear Andrew Daglish:

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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.
