Abstract:
A method of manufacturing a feedthrough dielectric body for an active implantable medical device includes the steps of: a) forming an alumina ceramic body in a green state, or, stacking upon one another discrete layers of alumina ceramic in a green state and pressing; b) forming at least one via hole straight through the alumina ceramic body; c) filling the at least one via hole with a ceramic reinforced metal composite paste; d) drying the alumina ceramic body and the ceramic reinforced metal composite paste; e) forming a second hole straight through the ceramic reinforced metal composite paste being smaller in diameter in comparison to the at least one via hole; f) filling the second hole with a substantially pure metal paste; g) sintering the alumina ceramic body, the ceramic reinforced metal composite paste and the metal paste; and h) hermetically sealing the feedthrough dielectric body to a ferrule.

Claim (Index 1):
A method of manufacturing a feedthrough dielectric body for an active implantable medical device, the method comprising the steps of:\n a) forming a ceramic body in a green state, or, stacking discrete layers of ceramic in a green state upon one another and pressing to form the ceramic body in the green state, the ceramic body having a first side opposite a second side; b) forming at least one via hole straight through the ceramic body extending between the first and second sides; c) filling the at least one via hole with a ceramic reinforced metal composite paste; d) drying the ceramic body and the ceramic reinforced metal composite paste; e) forming a second hole straight through the ceramic reinforced metal composite paste extending between the first and second sides, the second hole smaller in diameter in comparison to the at least one via hole, wherein a portion of the ceramic reinforced metal composite paste remains in the at least one via hole; f) filling the second hole with a substantially pure metal paste; g) sintering the ceramic body, the ceramic reinforced metal composite paste and the metal paste together to form the feedthrough dielectric body; and h) hermetically sealing the feedthrough dielectric body to a ferrule, the ferrule configured to be installed in an opening of a housing of the active implantable medical device.
