Patent ID: 7725190

Claim:
A medical device feedthrough assembly, comprising: a flat electrically conductive flange plate including a plurality of receptacles, wherein the flange plate is configured to be mounted to a housing of an implantable medical device; a plurality of feedthrough subassemblies, each subassembly including: an electrically conductive ferrule coupled to the flange plate, the ferrule being mounted within a corresponding receptacle of the plate; a feedthrough pin extending though the ferrule; and an insulator mounted within the ferrule, the insulator surrounding the feedthrough pin to isolate the feedthrough pin from the ferrule, the insulator being sealed to the ferrule, and the insulator being sealed to the feedthrough pin, wherein a first subassembly of the plurality of subassemblies includes an electronic filtering element coupled to the feedthrough pin thereof and mounted between the feedthrough pin thereof and the ferrule thereof, and wherein a second subassembly of the plurality of subassemblies includes no electronic filtering element coupled to the feedthrough pin thereof, and wherein the first and second subassemblies are configured to connect to electrical components of a medical device with internal couplings; and a conductive wall protruding from the flange plate, wherein the conductive wall is configured to extend over a length sufficient to span a gap between the flange plate and internal couplings of the filtered feedthrough pin of the second subassembly of the plurality of subassemblies and the unfiltered feedthrough pin subassembly of the plurality of subassemblies to shield the filtered feedthrough pin from the unfiltered feedthrough pin.
