Biomet Manufacturing Corp. is modifying the manufacturing process of ultrahigh molecular weight polyethylene (UHMWPE) used in the fabrication of polyethylene acetabular components. The modified manufacturing process results in a higher cross-linked polyethylene. The highly cross-linked UHMWPE is infused with medical grade Vitamin E.

This document, K070364, is a 510(k) summary for Biomet Manufacturing Corp.'s "100 kGy E-Poly™ MaxRom™ Acetabular Liners." This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, not for proving a device meets specific acceptance criteria through a clinical study.

Therefore, the requested information regarding acceptance criteria, device performance, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, and ground truth establishment is not available within this document.

Explanation:

• 510(k) Submissions: These submissions primarily focus on demonstrating that a new device is "substantially equivalent" to an already legally marketed device (the predicate device). This often involves non-clinical testing (e.g., material properties, mechanical testing) and comparison of indications for use, technological characteristics, and safety/effectiveness profiles.
• Lack of Clinical Data: The document explicitly states: "Clinical Testing: None provided as a basis for substantial equivalence." This means no human clinical trials were conducted or provided in this submission to evaluate the device's performance against clinical acceptance criteria.
• Focus on Manufacturing Modification: The core of this 510(k) is a modification to the manufacturing process of existing UHMWPE liners to create a higher cross-linked polyethylene infused with Vitamin E. The safety and effectiveness are supported by "substantial equivalence information, materials data, and testing results," which typically refers to non-clinical, benchtop, or in-vitro testing, not human clinical studies with patients.

In summary, as this is a 510(k) submission based on substantial equivalence and explicitly states no clinical testing was provided, the detailed information requested about acceptance criteria, clinical performance, and associated study methodology is not present.
