<p>1363305 Polysiloxane bonded carbon fibre composite R F HOCHMAN 2 Aug 1971 [6 Aug 1970] 36192/71 Heading C1A [Also in Divisions A5 and C3] A material used for forming body implants comprises graphite or boron fibres at least partially embedded in organic plastics material at least the surface of the implant being substantially chemically inert to internal human tissue. The organic plastics material preferably comprises an organo-polysiloxane. If an epoxy resin is used, the implant is given an external coating of inert material, e.g. an organopolysiloxane. The material preferably has a porous surface. When formed into a body implant, the fibres used in forming the implant may vary in orientation according to their position in the implant. The implant is preferably an orthopµdic prosthesis.</p> |
