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 33):
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 a ceramic body in a green state, the ceramic body having a ceramic body first side opposite a ceramic body second side; \n B) forming at least one first via hole comprising a first via hole inner surface extending along a longitudinal axis through the ceramic body to the ceramic body first and second sides; \n C) filling a CRMC paste that is made with a powder blend of ceramic and metal having been sintered and then ball-milled in the at least one first via hole, 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 ceramic body including the CRMC paste to thereby form a second CRMC material filling the at least one first via hole in the ceramic body; \n E) forming a second via hole extending through the second CRMC material to the ceramic body first and second sides so that an inner surface of the second CRMC material is spaced toward the longitudinal axis with respect to the first via hole inner surface; \n H) providing a platinum core in the second via hole; and \n I) sintering the ceramic body including the second CRMC material and the platinum core 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.
