Cemented and Uncemented Applications
Biomet Manufacturing Corp. is modifying the manufacturing process of ultrahigh molecular weight polyethylene (UHMWPE) used in the fabrication of polyethylene acetabular mgh molecular naglio partiles. The modified manufacturing process results in a higher cross-linked polyethylene. The highly cross-linked UHMWPE is infused with medical grade Vitamin E.
The provided text is a 510(k) Summary for a medical device (100 kGy E-Poly™ Acetabular Liners- Additional Profiles). It describes the device, its intended use, and claims substantial equivalence to a predicate device.
However, the provided document does not contain any information regarding acceptance criteria or a study that proves the device meets those criteria in the way a typical clinical performance study would.
Instead, it states:
- "Non-clinical laboratory testing was performed to determine substantial equivalence. The results indicated that the device was functional within its intended use."
- "Clinical Testing: None provided as a basis for substantial equivalence."
This means the submission relies on non-clinical (i.e., lab-based, not involving human patients) testing to demonstrate that the modified manufacturing process for the UHMWPE used in the acetabular liners results in a product that is substantially equivalent to the previously cleared predicate device (K050327 - E-Poly™ (Vitamin E) Acetabular Liners). Substantial equivalence means that the device is as safe and effective as a legally marketed predicate device.
Therefore, I cannot populate the table and answer the questions as requested because the document explicitly states that no clinical performance study was conducted or provided. The "acceptance criteria" here relate to the non-clinical tests demonstrating substantial equivalence, not clinical performance metrics.
If you are looking for a document that does include details on clinical studies, acceptance criteria, and ground truth establishment for a device's performance, this particular submission is not it, as it relies on non-clinical data for substantial equivalence.
§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
