Abstract
A feedthrough array for use in an implantable medical device is provided including an insulator, a plurality of conductive feedthrough pins extending through the insulator, and a ferrule including a flange extending inwardly from a ferrule sidewall along at least a majority of a length of a first ferrule side. A capacitor is disposed over the insulator and conductively coupled to the ferrule flange.
Claims18
A feedthrough array for use in an implantable medical device, comprising:
- an insulator;
- a plurality of conductive feedthrough pins extending through the insulator;
- a ferrule comprising a base portion adapted to be electrically and hermetically coupled to a housing of the medical device, a sidewall extending inwardly from the base portion, the sidewall including opposing first and second ferrule sides extending between opposing first and second ferrule ends forming a cavity there between for receiving the insulator, and at least one cross beam that extends between the opposing first and second ferrule sides, the at least one cross beam being located between two of the plurality of conductive feedthrough pins;
- a flange extending inwardly from the ferrule sidewall along at least a majority of a length of the first ferrule side, the flange having an interior surface, a top surface, and an exterior surface;
- a capacitor disposed over the insulator, the capacitor having an inner termination and an outer termination;
- a first conductive joint formed between the capacitor outer termination and the flange;
- and
- a plurality of second conductive joints formed between the capacitor inner termination and the plurality of conductive feedthrough pins.
