VASCU-GUARD Vascular Repair Patch is used in peripheral vascular reconstruction including the carotid, renal, iliac, femoral, profunda and tibial vessels and arteriovenous access revisions.
VASCU-GUARD Vascular Repair Patch (VASCU-GUARD) is derived from bovine pericardium procured from cattle originating in the United States. The pericardium is cross-linked with glutaraldehyde and treated with 1 molar sodium hydroxide for a minimum of 60 minutes at 20-25° (68-77°F). VASCU-GUARD is terminally sterilized using gamma irradiation and packaged within a sterile double-pouch system. The contents of the unopened, undamaged outer pouch are sterile. VASCU-GUARD is MR Safe. VASCU-GUARD utilizes animal tissue; patient must be informed prior to any procedure.
The provided text is a 510(k) summary for the VASCU-GUARD Vascular Repair Patch. It describes the device, its intended use, and comparison to predicate devices, along with performance data. However, this document does not contain information about acceptance criteria or specific studies that demonstrate the device meets those criteria in the context of an AI/ML medical device.
The performance data listed (Visual, Suture retention, Dimensional, Burst strength, Collagenase digestion, Denaturation Temperature, Water Permeability, Pliability, Chemical and heavy metal residuals, Bioburden, Pyrogenicity/Endotoxins, Temperature Excursion Testing, Biocompatibility Assessment) are for physical and material properties of the vascular repair patch itself, not for an AI/ML algorithm's diagnostic or predictive performance.
Therefore, I cannot provide the requested information regarding acceptance criteria, device performance, sample sizes, ground truth, expert qualifications, adjudication methods, or MRMC studies for an AI/ML device, as the supplied text pertains to a physical medical device (a vascular repair patch) and not an AI/ML product.
