The provided document is a 510(k) summary for the AXIAMED Trans-Sacral Spinal Access Device, which is a regulatory submission to the FDA. It does not contain information about acceptance criteria or a study proving the device meets acceptance criteria.

The document states that the FDA reviewed the premarket notification and determined the device is "substantially equivalent" to predicate devices marketed prior to May 28, 1976. This determination is based on a comparison to existing devices, not on specific performance criteria met through a dedicated study with ground truth, expert review, or statistical analysis (such as sample size, effect size, or MRMC studies).

Therefore, I cannot provide the requested information from the given text. The 510(k) summary focuses on device description, predicate devices, and the FDA's regulatory determination of substantial equivalence. It does not include the detailed study design and acceptance criteria typically found in clinical trial reports or validation studies.
