The Spirus Medical, Inc. Endo-Ease Endoscopic Overtube is indicated to aid endoscopic insertion and advancement to the mid-jejunum during diagnostic and therapeutic upper GI endoscopy. The Endo-Ease is used with an endoscope of appropriate diameter and length (such as an enteroscope or pediatric colonoscope).

The device described in this 510(k) consists of a sterile, single use, flexible overtube designed for use with currently marketed flexible endoscopes in the upper GI tract.

The provided text describes a 510(k) summary for a medical device called "Endo-Ease™ Endoscopic Overtube." This document is a regulatory submission to the FDA demonstrating substantial equivalence to a predicate device, rather than a clinical study report that would typically include detailed acceptance criteria and performance data as requested.

Therefore, the specific information about acceptance criteria, a study proving performance, sample sizes, ground truth establishment, expert qualifications, adjudication methods, MRMC studies, or standalone algorithm performance is not available in the provided text.

The document focuses on:

• Device Description: A sterile, single-use, flexible overtube for use with endoscopes in the upper GI tract.
• Indications for Use: To aid endoscopic insertion and advancement to the mid-jejunum during diagnostic and therapeutic upper GI endoscopy.
• Safety and Performance: Stated as being based on "design characteristics and comparison to legally marketed predicate devices."
• Conclusion: The device has been shown to be safe and effective based on indications for use, technological characteristics, performance testing, and predicate device comparison.

No specific acceptance criteria or study results are detailed in this 510(k) summary. The approval is based on substantial equivalence, implying that its performance is expected to be similar to the predicate devices and that any performance testing conducted would have been to support this equivalence, but the details of such testing are not provided.

The Spirus Medical, Inc. Endo-Ease Endoscopic Overtube is indicated for use with a flexible endoscope to aid in endoscopic insertion and advancement during diagnostic and therapeutic lower GI flexible endoscopy.

The device described in this 510(k) consists of a sterile, single use, flexible overtube designed for use with currently marketed flexible endoscopes in the lower & I tract.

I am sorry, but based on the provided text, there is no information about a study that proves the device meets specific acceptance criteria using performance metrics. This document is a 510(k) Premarket Notification summary for the Endo-Ease Endoscopic Overtube.

The document states that substantial equivalence was based on:

1. design characteristics
2. comparison to legally marketed predicate devices
3. performance testing which "consisted of destructive tensile testing of the helix and collars."

This 510(k) summary focuses on demonstrating that the new device is as safe and effective as a legally marketed predicate device, rather than providing detailed clinical study results with specific acceptance criteria and performance metrics typically found in efficacy studies.

Therefore, I cannot fulfill your request for the following information based on the provided text:

• A table of acceptance criteria and reported device performance.
• Sample size used for the test set and data provenance.
• Number of experts used to establish ground truth and their qualifications.
• Adjudication method for the test set.
• If a multi-reader multi-case (MRMC) comparative effectiveness study was done.
• If a standalone (algorithm only) performance study was done.
• The type of ground truth used.
• The sample size for the training set.
• How the ground truth for the training set was established.

The provided text describes a regulatory submission for a medical device (Endoscopic Overtube) and its clearance, which primarily relies on demonstrating equivalence to existing devices through design and specific engineering performance tests (destructive tensile testing), not clinical or diagnostic accuracy studies.
