Abstract:
1. A method of making a living tissue implantable component assembly, comprising the steps of: selecting a biocompatible 316L stainless steel part; selecting a biocompatible titanium part that is comprised of Ti-6Al-4V; selecting a laminated filler material that is less than about 0.010 inches thick that is comprised of a 22% to 98% nickel portion and a remaining titanium portion, said laminated filler material comprising at least two nickel layers surrounding at least one titanium layer, selecting said laminated filler material having a melting point that is lower than the melting point of said titanium part and said stainless steel part; positioning said filler material between said stainless steel part and said titanium part; placing the assembly in a non-reactive atmosphere; applying a force to said stainless steel part and said titanium part to place said filler material in compression, thereby creating intimate contact between said stainless steel part, said filler material, and said titanium part; heating the assembly to a temperature between said melting point of said laminated filler material and said melting point of said titanium part; holding the assembly at said bonding temperature for a predetermined time to form a bond between said stainless steel part and said titanium part; cooling the assembly; and implanting the component assembly in a human body.
