Abstract:
A method for manufacturing a feedthrough dielectric body for an active implantable medical device includes the steps of first forming a ceramic reinforced metal composite (CRMC) paste by mixing platinum with a ceramic material to form a CRMC material, subjecting the CRMC material to a first sintering step to thereby form a sintered CRMC material, ball-milling or grinding the sintered CRMC material to form a powdered CRMC material; and then mixing the powdered CRMC material with a solvent to form the CRMC paste. The method further includes forming an alumina ceramic body in a green state, forming at least one via hole through the alumina ceramic body, filling the via hole with the CRMC paste, drying the ceramic body including the CRMC paste to form a first CRMC material filling the via hole, forming a second via hole through the first CRMC material, providing a metal core in the second via hole, and subjecting the ceramic body including the first CRMC material and the metal core to a second sintering step to thereby form the dielectric body. The dielectric body is then sealed in a ferrule opening to form a feedthrough.

Claim (Index 32):
A method for manufacturing a feedthrough that is configured for incorporation into an active implantable medical device (AIMD), the method comprising the steps of:\n a) forming a ceramic dielectric body, comprising the steps of:\n A) forming an alumina ceramic body in a green state, the alumina ceramic body having a ceramic body first side opposite a ceramic body second side; \n B) forming at least one via hole comprising a first via hole inner surface extending along a longitudinal axis through the alumina ceramic body to the ceramic body first and second sides; \n C) filling the at least one via hole with a CRMC paste that is made from a sintered composite construct comprising platinum and, by weight or volume, about 15% to about 80% ceramic material, wherein the CRMC paste extends to a CRMC paste first end residing at or adjacent to the ceramic body first side and to a CRMC paste second end residing at or adjacent to the ceramic body second side; \n D) drying the alumina ceramic body including the CRMC paste to thereby provide a second CRMC material filling the at least one via hole in the alumina ceramic body; \n E) forming a counterbore or countersink in the second CRMC material from either the ceramic body first side or the ceramic body second side; \n F) filling the counterbore or countersink with a substantially pure metal paste; and \n G) sintering the alumina ceramic body including the second CRMC material and the substantially pure metal paste to thereby form the ceramic dielectric body; and \n b) providing an electrically conductive ferrule comprising a ferrule opening; and c) hermetically sealing the ceramic dielectric body to the ferrule in the ferrule opening.
