Annealing method for cross-linked polyethylene |
| abstract |
A method for making an ultra-high weight polyethylene (UHMWPE) medical implant starts with obtaining a preform consolidated from UHMWPE resin. Thereafter the preform is hot isostatically pressed at a temperature between 150°C and 190°C at a pressure up to 30,000 psi. After the hot isostatic pressing the preform is sequentially irradiated in a solid state at a total radiation dose of 2 to 10 MRad. The irradiated UHMWPE preform is then heated to a temperature of about 110°C to about 190°C for between 2 to 10 hours. The irradiated and heated preform is then cooled after each irradiation and heating to at or below 50°C, and thereafter a medical implant is formed from the preform. Alternately, the process can be performed on the medical implant itself. |
