I am sorry, but based on the provided text, there is no detailed information available regarding acceptance criteria, device performance metrics, or the actual study results that would allow me to populate the requested table and answer questions 2 through 9.

The document is a 510(k) premarket notification letter from the FDA to Hemedex, Inc. for their Fixation Device. It primarily states that the device has been found substantially equivalent to a predicate device (UreSil Fixation Device K914699).

Here's what the document does state in relation to performance testing:

• Section 7. Performance Testing: "Bench testing was conducted to demonstrate that this device meets the requirements of its intended use and meets the specified performance criteria."

However, this statement provides no specifics about:

• What those "specified performance criteria" were.
• The actual results of the "bench testing."
• The methodology, sample sizes, or ground truth establishment for any such testing.

Therefore, I cannot provide the requested information. The document only confirms that some bench testing was done to demonstrate the device meets its intended use and performance criteria, but it does not elaborate on these aspects in any way that fulfills the detailed questions asked.
