AI/ML Overview

The provided text is an FDA 510(k) clearance letter for the Intrelief device, indicating its substantial equivalence to predicate devices for use as a Transcutaneous Electrical Nerve Stimulator (TENS) and Electrical Muscle Stimulator (EMS) for pain relief and muscle performance, respectively.

This document does not contain any information regarding:

  • Acceptance criteria for device performance.
  • Study details (sample size, data provenance, expert qualifications, ground truth establishment, adjudication methods, MRMC studies, standalone performance) that would prove the device meets specific performance criteria.

Therefore, I cannot fulfill the request to describe the acceptance criteria and the study that proves the device meets the acceptance criteria based on the provided text. The FDA 510(k) clearance process primarily evaluates substantial equivalence to existing legally marketed devices, not necessarily a new clinical performance study against specific acceptance criteria for a novel technology.
