Abstract: Disclosed herein are electrically conductive and hermetic vias disposed within an insulator substrate of a feedthrough assembly and methods for making and using the same. Such aspects of the present invention consequently provide for the miniaturization of feedthrough assemblies inasmuch as the feedthrough components of the present invention are capable of supporting very small and hermetic conductively filled via holes in the absence of additional components, such as, for example, terminal pins, leadwires, and the like.

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.

Abstract: A co-fired hermetically sealed feedthrough is attachable to an active implantable medical device. The feedthrough comprises an alumina dielectric substrate comprising at least 96 or 99% alumina. A via hole is disposed through the alumina dielectric substrate from a body fluid side to a device side. A substantially closed pore, fritless and substantially pure platinum fill is disposed within the via hole forming a platinum filled via electrically conductive between the body fluid side and the device side. A hermetic seal is between the platinum fill and the alumina dielectric substrate, wherein the hermetic seal comprises a tortuous and mutually conformal interface between the alumina dielectric substrate and the platinum fill.
