The exGraft and exGraft Carbon ePTFE Vascular Grafts are indicated for use as vascular prostheses.

exGraft and exGraft Carbon ePTFE Vascular Grafts are intended for use as vascular prostheses for replacement or bypass of diseased vessels in patients suffering occlusive or aneurysmal diseases, in trauma patients requiring vascular replacement, for dialysis access, or for other vascular procedures.

The exGraft and exGraft Carbon ePTFE Vascular Grafts are single use sterile vascular grafts constructed of expanded polytetrafluoroethylene (ePTFE) with a radiopaque ink applied to the surface. The exGraft Carbon ePTFE vascular grafts also contain a carbon coating impregnated into the inner surface of the graft wall.

The provided text is a 510(k) summary from the FDA for a medical device called "exGraft ePTFE Vascular Grafts, exGraft Carbon ePTFE Vascular Grafts." This document primarily focuses on demonstrating substantial equivalence to a predicate device based on manufacturing changes, and does not contain information about the acceptance criteria or a study proving that the device meets those criteria in the context of an Artificial Intelligence/Machine Learning (AI/ML) device.

The document lists performance data that was included in the submission, such as:

• Burst Strength
• Strength after Repeated Puncture
• Tensile Strength
• Suture Retention Strength
• Kink Radius
• Water Entry Pressure
• Microscopic Porosity
• Wall Thickness Eccentricity
• Wall Thickness

However, these are engineering performance data points for a physical vascular graft, not metrics relevant to an AI/ML device's performance (e.g., accuracy, sensitivity, specificity).

Therefore, it is not possible to provide the requested information about acceptance criteria and a study proving an AI/ML device meets them, because this medical device is a physical vascular graft, not an AI/ML device. The request asks for details like "sample size used for the test set," "number of experts used to establish the ground truth," "adjudication method," "MRMC comparative effectiveness study," "standalone performance," and "type of ground truth," all of which are concepts applicable to AI/ML device validation, not to a physical vascular graft.

The 510(k) summary clearly states:

"The exGraft and exGraft Carbon ePTFE Vascular Grafts are single use sterile vascular grafts constructed of expanded polytetrafluoroethylene (ePTFE) with a radiopaque ink applied to the surface. The exGraft Carbon ePTFE vascular grafts also contain a carbon coating impregnated into the inner surface of the graft wall."

This describes a physical product, not a software device that would have AI/ML components requiring the type of performance study details requested.
