This document is a 510(k) summary for the NuVasive® Cement Restrictor, a medical device. As such, it does not contain any information about acceptance criteria or a study that proves the device meets such criteria.

The purpose of a 510(k) submission is to demonstrate substantial equivalence to a legally marketed predicate device, not to prove safety and effectiveness through new clinical studies. The document explicitly states:

• "G. Summary of Non-Clinical Tests (Not Applicable)."
• "H. Summary of Clinical Tests (Not Applicable)."

Therefore, I cannot provide the requested information from the provided text. The document indicates that safety and effectiveness are established through comparison to predicate devices, rather than through independent studies with acceptance criteria.
