Abstract
A component assembly for use in living tissue comprises: a ceramic part; a metal part; and a titanium palladium (Ti—Pd) interface layer for bonding said ceramic part to the metal part. In one embodiment, the interface layer may be formed from a single titanium layer in contact with a single palladium layer, or in other embodiments, may be at least a three layer laminate (Pd—Ti—Pd). A microstimulator housing comprising a ceramic part, a titanium or titanium alloy part sandwiching the Ti—Pd interlayer may be employed to create a eutectic bond that is strong and hermetic.
