The provided text is a 510(k) summary and FDA clearance letter for the "Uni-Patch Ultrasound Coupling Gel." This document focuses on the regulatory clearance process for a medical device (ultrasound gel) based on substantial equivalence to a predicate device, rather than a study evaluating the performance of an AI-powered diagnostic device against specific acceptance criteria.

Therefore, the information requested in your prompt regarding acceptance criteria, study design, expert involvement, and AI performance metrics is not available in the provided text. The document states:

• "Performance FDA has not established special controls or performance standards for this device"
• "Uni-Patch Ultrasound Coupling Gel is similar in terms of intended use and technological characteristics to predicate devices reviewed as coupling gels used to couple ultrasound device is similar with respect to indications for use and physical characteristics to predicate devices in terms of section 510(k) substantial equivalency."

This indicates that the clearance was based on demonstrating similarity to existing, legally marketed ultrasound gels, not on a new, controlled performance study with the metrics you've outlined for AI/diagnostic devices.
