Abstract
A feedthrough apparatus for a implantable medical device having a casing includes a conductive housing having an outer side, an inner side, and a peripheral surface with a continuous assembly groove therein for mounting on the casing of the implantable medical device. The conductive housing has first and second through bores extending between the outer side and the inner side in spaced apart, generally parallel, relationship. First and second filtered feedthrough assemblies are received, respectively, in the first and second through bores. Each filtered feedthrough assembly includes an insulative terminal, a filter capacitor, and a plurality of lead wires electrically isolated from the conductive housing supported on and extending through the insulative terminal and through the filter capacitor in conductive relation therewith. Also, a backfill port is provided on the conductive housing and has a passageway extending between the inner side and the outer side.
