AI/ML Overview

The provided text is a 510(k) summary for the Avanta Orthopaedics Trapezium Implant. It describes the device, its intended use, and compares it to a predicate device. However, it does not contain any information about acceptance criteria, device performance studies, sample sizes, ground truth establishment, or expert involvement in such studies.

Therefore, I cannot fulfill your request for a table of acceptance criteria and reported device performance or any other details about a study proving the device meets acceptance criteria. The document is a regulatory submission for substantial equivalence, not a clinical study report.

The FDA's finding of "substantial equivalence" in this context means the device is considered as safe and effective as a legally marketed predicate device, based on comparison, not necessarily based on a new performance study proving specific acceptance criteria.
