ConvaTec Non-Adhesive Dressing is indicated for use on moderately to heavily exuding chronic wounds such as pressure ulcers, leg ulcers and diabetic ulcers, and on moderately to heavily exuding acute wounds such as abrasions, lacerations, biopsies, and open and closed surgical wounds. The dressing may be used alone or in combination with other primary dressings to manage wound exudate.
ConvaTec Non-Adhesive Dressing is a sterile, absorbent wound dressing comprised of an absorbent pad containing acrylic polymer affixed to a hydrocolloid layer.
The provided 510(k) summary for the ConvaTec Non-Adhesive Dressing (K972062) primarily focuses on demonstrating substantial equivalence to a predicate device through comparison of design, intended use, composition, and dressing characteristics, along with biocompatibility testing. It does not include a study that establishes performance against specific acceptance criteria for diagnostic accuracy or device effectiveness in a clinical setting in the way an AI/ML device submission would.
Therefore, many of the requested elements for an AI/ML study (like sample size for test sets, ground truth methodology, expert qualifications, adjudication, MRMC studies, or standalone performance) are not applicable or extractable from this document.
Here's an attempt to answer the questions based on the available information, noting the limitations:
1. A table of acceptance criteria and the reported device performance
Based on the document, the "acceptance criteria" are implied by the requirements for substantial equivalence to the predicate device and satisfactory biocompatibility. The reported "performance" relates to meeting these equivalence and safety standards.
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Substantial equivalence to ConvaTec's CombiDERM™ ACD™ in: | ConvaTec Non-Adhesive Dressing is substantially equivalent to ConvaTec's CombiDERM™ ACD™ in design, intended use, composition, and dressing characteristics. |
| - Design | Equivalent |
| - Intended Use | Equivalent |
| - Composition | Equivalent |
| - Dressing Characteristics | Equivalent |
| Biocompatibility: | ConvaTec Non-Adhesive Dressing demonstrated: |
| - Non-irritating | Non-irritating |
| - Non-cytotoxic | Non-cytotoxic |
| - Non-hemolytic | Non-hemolytic |
| - Weak allergenic potential | Weak allergenic potential |
2. Sample size used for the test set and the data provenance
Not applicable. This device is a wound dressing, not an AI/ML diagnostic device that uses a test set of data. The "test set" would be the samples used for the biocompatibility studies, but specific numbers and provenance are not detailed beyond "Biocompatibility tests for ConvaTec Non-Adhesive Dressing".
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. Ground truth as typically defined for AI/ML diagnostic studies is not relevant here. Biocompatibility testing is typically performed by laboratory scientists.
4. Adjudication method for the test set
Not applicable. No diagnostic test set requiring adjudication is described.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This is a physical wound dressing, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a physical wound dressing.
7. The type of ground truth used
For the biocompatibility claims, the "ground truth" was established by standard laboratory tests and observations for irritation, cytotoxicity, hemolysis, and allergenicity. For the substantial equivalence claim, the "ground truth" was a comparison to the existing predicate device, CombiDERM™ ACD™.
8. The sample size for the training set
Not applicable. This is a wound dressing, 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 a wound dressing.

510(k) Premarket Notification ConvaTec Non-Adhesive Dressing
Item 8: SUMMARY OF SAFETY AND EFFECTIVENESS
The purpose of this 510 (k) Premarket Notification is to request clearance to market ConvaTec Non-Adhesive Dressing.
ConvaTec Non-Adhesive Dressing is a sterile, absorbent wound dressing comprised of an absorbent pad containing acrylic polymer affixed to a hydrocolloid layer. The dressing is intended for use on moderately to heavily exuding chronic wounds such as pressure ulcers and diabetic ulcers and for moderately to heavily exuding acute wounds, such as abrasions, biopsies, and open and closed surgical wounds. The dressing may be used alone or in combination with other primary dressings to manage wound exudate.
ConvaTec Non-Adhesive Dressing is contraindicated for use on individuals with a known sensitivity to the dressing or its components.
ConvaTec Non-Adhesive Dressing is substantially equivalent to ConvaTec's CombiDERM™ ACD™ The dressings are equivalent in design, intended use, composition and dressing characteristics.
Biocompatibility tests for ConvaTec Non-Adhesive Dressing have demonstrated that this product is nonirritating, non-cytotoxic, non-hemolytic and has a weak allergenic potential. The results of these studies are enclosed in Item 5 of this application.

Dear Ms. McNally:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). You may, therefore, market your device subject to the general controls provisions of the Federal Food, Drug, and Cosmetic Act (Act) and the following limitations:
-
- This device may not be labeled for use on third degree burns.
- This device may not be labeled as having any accelerating effect on the rate 2. of wound healing or epithelization.
- 3 This device may not he labeled as a long-term. permanent, or no-change dressing, or as an artificial (synthetic) skin.
- This device may not be labeled as a treatment or a cure for any type of 4. wound.
The labeling claims listed above would be considered a major modification in the intended use of the device and would require a premarket notification submission (21 CFR

807.81).The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practices, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or ciass III ( (Premarket Approval) it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations (CFR), Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practices (GMP) for Medical Devices: General GMP regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 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 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4595.
