The provided document is a 510(k) Summary for the EasyStim TN28 OTC device, a Transcutaneous Electrical Nerve Stimulator (T.E.N.S.). It focuses on demonstrating substantial equivalence to predicate devices rather than presenting a detailed study proving the device meets specific acceptance criteria in the context of diagnostic or treatment performance.
Here's an analysis based on the information provided, addressing the questions as best as possible within the scope of the document:
1. A table of acceptance criteria and the reported device performance
The document does not explicitly state acceptance criteria in terms of clinical performance metrics (e.g., sensitivity, specificity, accuracy) for diagnosis or treatment effectiveness, as would be common for AI/ML-based medical devices or novel therapies. Instead, the substantial equivalence hinges on meeting electrical safety, electromagnetic compatibility, usability, risk management standards, and having similar technical characteristics and indications for use as predicate devices.
The "device performance" reported is primarily a comparison of its technical specifications to those of legally marketed predicate devices.
