The Collagen Wound Dressing is indicated for the management of exuding wounds including: Full thickness and partial thickness wounds Pressure and venous ulcers Ulcers caused by mixed vascular etiologies Diabetic ulcers Partial thickness burns Donor sites and other bleeding surface wounds Abrasions Traumatic wound healing by secondary intention Dehisced surgical incisions
Collagen Wound Dressing is an advanced wound care device composed of pure freezedried cross-linked bovine collagen. It is a sterile, absorbent, white, porous, topical wound dressing. As a primary wound dressing, it can be cut to any size or be used in multi-layers to fit wound. It can also be used in combination with either occlusive or semi-occlusive secondary dressing. The product is biodegradable.
The provided text does not describe a study that proves a device meets acceptance criteria for an AI/ML medical device. Instead, it is an FDA 510(k) clearance letter for a Collagen Wound Dressing, which is a physical medical device, not an AI/ML software.
The document discusses non-clinical data, performance tests (e.g., appearance, weight, absorption, pH, heavy metals, sterility, SEM, DSC, FTIR), biocompatibility, sterilization, and shelf-life studies. It explicitly states, "No clinical study is included in this submission."
Therefore, I cannot extract the information for an AI/ML medical device as requested, because the provided text is about a physical wound dressing and does not contain any details related to:
- Acceptance criteria for an AI/ML algorithm's performance (e.g., sensitivity, specificity, AUC)
- Sample sizes for test sets used in AI/ML validation
- Number/qualifications of experts for ground truth establishmen
- Adjudication methods
- MRMC studies
- Standalone algorithm performance
- Type of ground truth (e.g., pathology, outcomes data) in the context of an AI/ML model
- Training set details for an AI/ML model
The request's template is specifically designed for AI/ML device evaluations, which is not applicable to the content of this FDA clearance letter.

Dear Ziling Shangguan:
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.

6. Non-Clinical Data/Information
The following non-clinical data and performance data are provided to demonstrate the safety and performance of the proposed device for its intended use and to support a
{6}------------------------------------------------
determination of substantial equivalence.
Biocompatibility
Based on Table A.1 of ISO 10993-1 and Table A.1 of "Use of International Standard ISO 10993-1, Biological evaluation of medical devices-Part 1 Evaluation and testing within a risk management process", the proposed device is categorized as surface device for breached or compromised surface with permanent duration, the relevant biocompatibility endpoints were conducted tests or evaluation as required. The results showed that Collagen Wound Dressing meets biocompatibility requirements of the ISO 10993-1 standard and FDA Guidance. The proposed device raised no new safety concerns for biocompatibility to the predicate device.
Biocompatibility tests included: cytotoxicity, acute systemic toxicity, subcutaneous implantation, irritation, subacute systemic toxicity, pyrogenicity, skin sensitization, and chemical characterization.
Performance Test
A series of bench tests were conducted which included an evaluation of physical, chemical, and biological properties. Results of the testing confirm that the proposed device meets all product performance requirements for the intended use and demonstrates substantial equivalence to the predicate device.
The following performance tests were conducted on proposed devices: Appearance, Weight, Free swell absorption, pH value, Heavy metals, Hydroxyproline assay, Bacterial Endotoxins, Sterility, Scanning Electron Microscope (SEM), Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR).
Sterilization and Shelf Life
The proposed device is provided sterile and will subject to an irradiation sterilization process by gamma ray, in its final package to achieve a Sterility Assurance Level (SAL) of 10 %. The validation study for radiation sterilization dose establishment is carried out

according ISO 11137-1/-2:2013, ISO11137-3:2017, ISO11737-1:2018, ISO 11737-2:2019. The results for the sterility testing showed that, the products achieved a SAL of 10-6 after the irradiation sterilization process.
A proposed 3 years real time aging test is being conducted per FDA guidance on shelf life. Now we have finished the one-year test. So a maximum shelf life of one (1) years should be assigned to the proposed device, when stored in when stored in a cool (below 25 °C) place, avoid excessive light and humidity (below 50%), in accordance with the manufacturer's recommendations. The shelf life is based on an assessment of the seal integrity of the sterile barrier packaging and functional testing of device. The results demonstrated that all performance indicators of the proposed device meet the requirements.
Animal-Derived Materials Safety Information
Based on utilization of animal derivative materials in Collagen Wound Dressing, the relevant requirements of safety is compliant with FDA guidance document-Medical Devices Containing Materials Derived from Animal Sources (Except for In Vitro Diagnostic Devices) and ISO 22442 standards. Animal testing, biocompatibility testing, chemical characterization studies and inactivation study of viruses confirmed the safety of proposed device.
