KeriCure™ Liquid Bandage and KeriCure Natural Seal™ Liquid Bandage: To help cover and protect the skin from infection in minor cuts, scrapes, burns, irritations and abrasions.
KeriCure™ Advanced Liquid Bandage: To cover and protect the skin from infection in minor cuts, scrapes, burns, irritations and abrasions, as well as closed surgical incisions and excisions.
The KeriCure™ Liquid Bandage family of products is comprised of a protective, elastic polymer film (proprietary polyacrylate polymer). As applied to the skin, the liquid bandage is slightly more viscous than water and sets within minutes to form a clear, breathable and completely transparent film. The Liquid Bandage is capable of adhering to both intact and compromised body tissue. The device is available with either a dropper or spray applicator.
The provided text describes information about the KeriCure™ Advanced Liquid Bandage, a medical device, and its substantial equivalence to predicate devices, focusing on performance and biocompatibility testing. However, it does not contain the specific information requested in your prompt regarding acceptance criteria, study details, human expert involvement, or AI-related effectiveness.
Here's an analysis of what is available vs. what is not:
Information Present in the Document:
- Device Name: KeriCure™ Advanced Liquid Bandage, KeriCure™ Liquid Bandage, KeriCure Natural Seal™ Liquid Bandage.
- Intended Use: To cover and protect the skin from infection in minor cuts, scrapes, burns, irritations and abrasions, as well as closed surgical incisions and excisions (for Advanced version).
- Product Code: KMF (Liquid bandage)
- Regulatory Class: Class I
- Predicate Devices: K083913 – NUVADERM – Chesson Labs; K991920 – Dermaphylyx Hydrophilic Wound Dressing, Dermaphylyx, Inc.
- Biocompatibility Testing: Passed ISO 10993-10 for irritation and skin sensitization. Cytotoxicity testing performed according to 10993-5, with spray applicator scoring 1.
- Shelf Life Testing: Performed according to ISO11737-1, ASTM F1980, USP-51 and USP-35, indicating a 12-month shelf life.
- Performance Testing (General): "Performance testing for KeriCure™ Liquid Bandages was performed according to the following standards: ASTM 570, ASTM D638-10, ASTM D789, E96/ E96M-10. The applicant device passed all testing requirements with results similar to the predicate devices in terms of performance capabilities."
- Substantial Equivalence: Claimed based on similar fundamental technological characteristics (flexible wound management, moisture barrier, absorptive qualities, infection protection) and verified by test results in design, materials, and intended use.
Information NOT present in the Document (that you requested):
- A table of acceptance criteria and the reported device performance: While general statements about "passing all testing requirements" are made, specific numerical acceptance criteria (e.g., "tear strength must be > X N/mm") and the device's exact reported performance values are not provided.
- Sample size used for the test set and the data provenance: The document mentions "testing requirements" and "test results" but does not specify the sample sizes (e.g., number of bandages tested, number of subjects in a trial) or the origin of the data (e.g., country, retrospective or prospective).
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: This device is a liquid bandage, not typically an AI-driven diagnostic tool that relies on expert interpretation of images or other data for ground truth establishment. Therefore, this information is not relevant or present.
- Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable for this type of device testing.
- 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: This is explicitly for AI-assisted diagnostic or interpretative devices. The KeriCure™ Advanced Liquid Bandage is a physical wound dressing; it does not involve AI or human readers for diagnostic purposes.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable, as this is not an AI algorithm.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc): For the performance characteristics mentioned (e.g., elasticity, water vapor transmission), the "ground truth" would be established by the defined parameters within the ASTM/ISO standards themselves, rather than expert consensus or pathology data. For biocompatibility, the ground truth is the absence of irritation, sensitization, or cytotoxicity as defined by the ISO standards.
- The sample size for the training set: Not applicable, as this is not a machine learning/AI device requiring a training set.
- How the ground truth for the training set was established: Not applicable for the same reason as above.
In summary: The provided text details the regulatory clearance for a liquid bandage, including its intended use, predicate devices, and general statements about biocompatibility and performance testing against established standards. However, it lacks the specific quantitative data, study designs, and human expert involvement details that would be found in a submission for an AI-powered diagnostic device or a study designed to evaluate human performance with and without AI assistance.
§ 880.5090 Liquid bandage.
(a)
Identification. A liquid bandage is a sterile device that is a liquid, semiliquid, or powder and liquid combination used to cover an opening in the skin or as a dressing for burns. The device is also used as a topical skin protectant.(b)
Classification. Class I (general controls). When used only as a skin protectant, the device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 880.9.
