Abstract: A feedthrough filter capacitor assembly comprising a terminal pin connector is described. The terminal pin connector is designed to facilitate an electrical connection between the terminal pin comprising a multitude of compositions to a circuit board of an implantable medical device. The terminal pin connector comprises a clip portion positioned within a connector housing. The connector clip mechanically attaches to the terminal pin of the feedthrough with at least one prong and an exterior surface of the connector housing electrically contacts the circuit board, creating an electrical connection therebetween. The connector housing comprises a material that is conducive to a weld or solder attachment process to the circuit board. The feedthrough filter capacitor assembly is particularly useful for incorporation into implantable medical devices such as cardiac pacemakers, cardioverter defibrillators, and the like, to decouple and shield internal electronic components of the medical device from undesirable electromagnetic interference (EMI) signals.

Abstract: A method for manufacturing a singulated feedthrough insulator for a hermetic seal of an active implantable medical device (AIMD) is described. The method begins with forming a green-state ceramic bar with a via hole filled with a conductive paste. The green-state ceramic bar is dried to convert the paste to an electrically conductive material filling via hole and then subjected to a pressing step. Following pressing, a green-state insulator is singulated from the green-state ceramic bar. The singulated green-state insulator in next sintered to form an insulator that is sized and shaped for hermetically sealing to close a ferrule opening. The thusly produced feedthrough is suitable installation in an opening in the housing of an active implantable medical device.

Abstract: An insulative feedthrough attachable to an active implantable medical device includes a feedthrough body having a material which is both electrically insulative, biocompatible and separates a body fluid side from a device side. A passageway is disposed through the feedthrough body. A composite conductor is disposed within the passageway and has a body fluid side metallic wire electrically conductive to a device side metallic wire. The body fluid side metallic wire extends from a first end disposed inside the passageway to a second end on the body fluid side. The device side metallic wire extends from a first end disposed inside the passageway to a second end on the device side. The body fluid side metallic wire is hermetically sealed to the feedthrough body. The body fluid side metallic wire is biocompatible and is not the same material as the device side metallic wire.

Abstract: A hermetically sealed feedthrough for attachment to an active implantable medical device includes a dielectric substrate configured to be hermetically sealed to a ferrule or an AIMD housing. A via hole is disposed through the dielectric substrate from a body fluid side to a device side. A conductive fill is disposed within the via hole forming a filled via electrically conductive between the body fluid side and the device side. A conductive insert is at least partially disposed within the conductive fill. Then, the conductive fill and the conductive insert are co-fired with the dielectric substrate to form a hermetically sealed and electrically conductive pathway through the dielectric substrate between the body fluid side and the device side.

Abstract: A hermetically sealed feedthrough filter assembly is attachable to an active implantable medical device and includes an insulator substrate assembly and a feedthrough filter capacitor disposed on a device side. A conductive leadwire has a proximal leadwire end extending to a distal leadwire end, wherein the proximal leadwire end is connectable to electronics internal to the AIMD. The distal leadwire end is disposed at least partially through a first passageway of the feedthrough filter capacitor and is in contact with, adjacent to or near a device side conductive fill. A first electrically conductive material makes a three-way electrically connection that electrically connects the device side conductive fill to an internal metallization of the feedthrough filter capacitor and to the distal leadwire end. A second electrically conductive material electrically connects an external metallization of the feedthrough filter capacitor to a ferrule or an AIMD housing.

Abstract: A self-centering washer is positioned between a feedthrough and a filter circuit board. The washer has openings through which first and second terminal pins extend. A first opening has an inner arcuate portion contacting the first terminal pin and an outer perimeter portion exposing the braze sealing the terminal pin to the insulator. A second opening has an inner arcuate portion contacting the second terminal pin and an outer perimeter portion exposing the braze sealing the terminal pin to the insulator. In an imaginary configuration with the first and second washer openings superimposed one on top of the other, the cumulative arcuate distance of the inner arcuate portions about one of the terminal pins, subtracting overlap, results in a gap between the superimposed washer openings that is less than a diameter of the first and second terminal pins so that the washer is prevented from lateral movement.
