AI/ML Overview

The provided text is a 510(k) Summary for the Endofresh Digestive Endoscopy System (K192704). It primarily focuses on demonstrating substantial equivalence to a predicate device (K100584, EVIS EXERA II 180 System) through non-clinical testing and comparison of specifications.

Unfortunately, the document does not contain information about acceptance criteria for specific performance metrics, nor does it detail a study proving the device meets particular acceptance criteria for diagnostic accuracy or effectiveness in a clinical setting.

Instead, the document highlights that no clinical study was included in the submission (Section 9. Clinical Test Conclusion). The determination of substantial equivalence is based on non-clinical tests (electrical safety, EMC, product performance against standards like ISO 8600-1, biocompatibility, etc.) and a comparison of technical specifications between the proposed device and the predicate device.

Therefore, I cannot provide the requested table of acceptance criteria and reported device performance or information regarding sample sizes, ground truth establishment, expert adjudication, or MRMC studies for diagnostic performance, as these are not present in the provided text.

However, I can extract the information that is available regarding non-clinical testing and the comparison with the predicate device:


1. Table of Acceptance Criteria and Reported Device Performance

As noted, the document does not present explicit acceptance criteria for diagnostic performance or reported clinical performance data. It focuses on adherence to recognized standards and comparison of technical specifications.
