Abstract:
1. A process for the sterile packaging of a prosthetic implant made of polyethylene comprising: successively placing the implant in a flexible, gas-impermeable sachet having an opening adapted to be sealed, creating a vacuum in the sachet and then sealing its opening; placing the sachet containing the implant in a gas-impermeable envelope including an opening adapted to be sealed; establishing an inert gaseous atmosphere in the envelope by injecting an inert gas inside the envelope until the pressure inside the envelope reaches a predetermined pressure less than atmospheric pressure; closing the envelope hermetically by sealing its opening; and sterilizing the implant within the sachet and the envelope by irradiation, wherein a pressure of the inert gas in the envelope is greater than or equal to a pressure in the sachet.
