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.
