  • Wear-resistant olefinic medical implant and thermal treatment container therefor
    Patent number: 6355215
    Abstract: A prefabricated medical implant made of polymeric material having increased wear resistance without substantially changing its ductility and other physical properties is described. The implant is formed by a method including the steps of heating a sealed, packaged, prefabricated implant, having a reduced oxygen atmosphere, to an elevated temperature below its annealing point at a predetermined rate and held at that temperature for a predetermined time. After this time the packaged implant, while being maintained in a predetermined temperature range, is irradiated with a predetermined amount of gamma radiation. After irradiation, the implant is permitted to cool at a predetermined rate. Thermal conductive and thermal insulation containers are also provided for holding the packaged implants during the process.
