Not Found

The provided FDA 510(k) clearance letter for the Momcozy Wearable Breast Pump (BP311) does not contain information about acceptance criteria, study design, or performance metrics that would typically be found in a submission for a device with complex algorithms or AI components.

The letter explicitly states:
"We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent... to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976..."

This indicates a traditional 510(k) pathway where the device's substantial equivalence to a predicate is demonstrated, primarily through comparison of technological characteristics, materials, and intended use. Performance testing for breast pumps typically focuses on aspects like suction pressure, cycle rate, duration of use without overheating, and material biocompatibility, rather than AI-driven diagnostic accuracy or human-in-the-loop performance.

Therefore, I cannot provide the requested information regarding acceptance criteria, study data, ground truth establishment, or expert involvement as these details are not present in the provided document. The device in question, a wearable breast pump, does not appear to involve AI or complex algorithms that would necessitate such detailed performance studies as those typically seen for imaging or diagnostic AI/ML devices.

The provided document is a 510(k) clearance letter from the FDA for the Momcozy Wearable Breast Pump (BP137) and Momcozy Wearable Breast Pump (BP141).

This type of document does not contain the information requested regarding acceptance criteria and performance studies. 510(k) clearance letters primarily state that the FDA has determined the device is substantially equivalent to a legally marketed predicate device and outline regulatory requirements.

Information about specific performance studies, acceptance criteria, sample sizes, expert qualifications, and ground truth establishment is typically found in the 510(k) premarket notification submission itself, which is not included in this letter.

Therefore, I cannot provide answers to the questions based on the given text.
