Implantable medical device having a feedthrough, a feedthrough and method for making such feedthrough. The feedthrough has a ferrule, an electrically conductive pin, a preform having a preform liquidus temperature, a capacitor, positioned within the ferrule abutting the preform, having a coating having a coating liquidus temperature and being configured to electrically couple with the preform, and an insulative assembly configured, at least in part, to seal against passage of a liquid through the ferrule, and having an insulative assembly liquidus temperature. The coating liquidus temperature is greater than the preform liquidus temperature and the coating liquidus temperature being greater than the insulative assembly liquidus temperature.

Implantable medical device and feedthrough and method of making same

A connector assembly for an implantable medical device includes a plurality of feedthroughs mounted in a conductive array plate, each feedthrough in the plurality of feedthroughs including a feedthrough pin electrically isolated from the conductive array plate by an insulator and an electronic module assembly including a plurality of conductive strips set in a non-conductive block. The plurality of conductive strips is in physical and electrical contact with the feedthrough pins at an angle of less than 135 degrees. The connector assembly further includes at least one circuit, the circuit including a plurality of conductors corresponding to the plurality of feedthroughs. The plurality of conductors of the circuit is in physical and electrical contact with a corresponding one of the conductive strips of the plurality of conductive strips of the electronic module assembly at an angle of less than 135 degrees.

Compact connector assembly for implantable medical device

A filtering capacitor feedthrough assembly for an implantable active medical device is disclosed. The filtering capacitor feedthrough assembly includes a capacitor having an aperture defined by an inner capacitor surface. The capacitor is electrically grounded to an electrically conductive feedthrough ferrule or housing of the implantable active medical device. A terminal pin extends into the aperture. An electrically conductive split ring sleeve is disposed within the aperture and between the terminal pin and the capacitor. The split ring sleeve includes a first end, a second end, a sleeve length therebetween. A longitudinal slit through the sleeve extends from the first end to the second end. The electrically conductive split ring sleeve mechanically securing and electrically coupling the terminal pin to the capacitor.

Filtering capacitor feedthrough assembly

A method for coupling a capacitor to a feedthrough assembly that includes a ferrule and a terminal pin therethrough is provided. The method comprises dispensing an epoxy onto an outer surface of the feedthrough assembly. A capacitor, which has an opening therethrough for receiving the terminal pin and cooperates therewith to form a cavity, is placed over the ferrule to contact the epoxy. A weight is placed on the capacitor to position it with respect to the terminal pin, and the epoxy is cured.
