(248 days)
The SIS Wound Dressing is intended for temporary coverage of partial-thickness skin loss injury, such as burns, abrasions, decubitus and chronic vascular ulcers, and autograft donor sites. This device is intended for one-time use.
The SIS Wound Dressing is supplied in sheet form in sizes ranging from 16 cm3 to 360 cm². The device is supplied sterile and is intended for one-time use. Reasonable assurance of biocompatibility of the materials comprising the SIS Wound Dressing is provided by the established history of use of porcine-derived tissues in medical product manufacturing as well as meeting the requirements of the appropriate biocompatibility tests.
This is a 510(k) premarket notification for the SIS Wound Dressing, a porcine-derived wound dressing. The submission asserts substantial equivalence to predicate devices for temporary coverage of partial-thickness skin loss injuries.
Based on the provided documents, here's a breakdown of the acceptance criteria and the study information:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Biocompatibility (established history of use of porcine-derived tissues in medical product manufacturing) | Met requirements of appropriate biocompatibility tests. |
| Substantial Equivalence to predicate devices (indications for use, materials, physical construction) | Deemed substantially equivalent to legally marketed predicate devices. |
| Sterility | Supplied sterile. |
| One-time use | Intended for one-time use. |
| Manufacturing Process Controls and Quality Assurance Program | Device will be manufactured according to specified process controls and a Quality Assurance Program. |
Important Limitations/Labeling Restrictions (effectively negative acceptance criteria):
- May not be labeled for use on third-degree burns.
- May not be labeled as having any accelerating effect on the rate of wound healing or epithelization.
- May not be labeled as a long-term, permanent, or no-change dressing, or as an artificial (synthetic) skin.
- May not be labeled as a treatment or a cure for any type of wound.
2. Sample size used for the test set and the data provenance
The provided documents do not describe a specific clinical study with a test set of patient data for evaluating the performance of the SIS Wound Dressing. The substantial equivalence determination is primarily based on:
- Established history of use: Porcine-derived tissues in medical product manufacturing.
- Biocompatibility testing: The device "meeting the requirements of the appropriate biocompatibility tests." No sample size or specific provenance for this testing is provided, but it would typically be conducted on animal models or in-vitro.
- Comparison to predicate devices: The submission states the device is similar in indications for use, materials, and physical construction to already marketed devices.
Therefore, there is no information on:
- Sample size used for a clinical test set.
- Data provenance (country of origin, retrospective/prospective).
3. Number of experts used to establish the ground truth for the test set and qualifications of those experts
As there is no described clinical test set with patient data, there is no information on experts establishing ground truth for such a set.
4. Adjudication method
No clinical test set is described, so no adjudication method is provided.
5. Multi-Reader Multi-Case (MRMC) comparative effectiveness study
No MRMC study is mentioned or implied. The 510(k) pathway for this device relies on substantial equivalence and biocompatibility, not comparative effectiveness against human readers.
6. Standalone (algorithm only without human-in-the-loop performance) study
This device is a physical wound dressing, not an algorithm or AI. Therefore, the concept of a standalone algorithm performance study is not applicable.
7. Type of ground truth used
For the biocompatibility claims, the "ground truth" would be the results of the specific biocompatibility tests performed, verified against established standards. For the substantial equivalence argument, the "ground truth" is the established performance and safety profile of the predicate devices.
8. Sample size for the training set
This device is a physical product, not a machine learning model. Therefore, the concept of a "training set" in an AI/algorithm context is not applicable.
9. How the ground truth for the training set was established
Not applicable, as there is no training set in the context of an AI/algorithm.

Proposed Classification Name:
Not Classified, FDA proposed classification: Porcine Burn Dressings 21 CFR Part 878.4026 or 878.4140, (79KG)
Predicate Devices:
The SIS Wound Dressing is similar to predicate tissue-derived wound dressings that are currently marketed, having the same intended use of temporary coverage of partialthickness skin loss injuries.
Device Description:
The SIS Wound Dressing is supplied in sheet form in sizes ranging from 16 cm3 to 360 cm². The device is supplied sterile and is intended for one-time use. Reasonable assurance of biocompatibility of the materials comprising the SIS Wound Dressing is provided by the established history of use of porcine-derived tissues in medical product manufacturing as well as meeting the requirements of the appropriate biocompatibility tests.
Substantial Equivalence:
The SIS Wound Dressing will be manufactured according to specified process controls and a Quality Assurance Program. This device is similar with respect to indications for use, materials and physical construction to predicate devices in terms of section 510(k) substantial equivalency.

Re: K973170 Trade Name: SIS Wound Dressing Regulatory Class: Unclassified Product Code: KGN Dated: March 27, 1998 Received: March 30, 1998
Dear Dr. Fearnot:
This letter corrects our substantially equivalent letter of April 30, 1998.
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 (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 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 of wound healing or epithelization.
-
This device may not be labeled as a long-term, permanent, or no-change dressing, or as an artificial (synthetic) skin.
{2}------------------------------------------------
Page 2 - Neal E. Fearnot, Ph.D.
- This device may not be labeled as a treatment or a cure for any type of 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).
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); 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.
This letter will allow you to continue marketing your device as described in your Section 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.
