Patent ID: 7210966

Claim:
A multi-polar array for an implantable medical device, comprising; a titanium ferrule surrounding the outer periphery of the array and adapted to mechanically couple to a corresponding inner periphery of a titanium surface of an implantable medical device, said ferrule having a plurality of conductive pin-receiving bores formed through a major surface thereof, and wherein said ferrule consists of one of grade 4 titanium and grade 5 titanium; a plurality of electrically insulative members sealingly disposed within each said plurality of bores and wherein each of said members is adapted to receive at least one conductive feedthrough pin; a plurality of conductive feedthrough pins, each said pin disposed within one of said plurality of electrically insulative members; and a plurality of capacitive elements adapted to reduce or eliminate electromagnetic interference from at least some of the plurality of the conductive feedthrough pins, effectively disposed proximate said at some of the plurality of the conductive feedthrough pins wherein the plurality of conductive feedthrough pins exceeds the plurality of capacitive elements by at least one pin, so that an analog and/or digital signal coupled to a non-capacitively filtered feedthrough pin substantially completely conducts via said pin.
