Abstract: An active medical device has a feedthrough comprising a ferrule sealed to a ceramic insulator supporting a short terminal pin and a long terminal pin that are connected to electronic components in the device housing. A silicone insulator residing in the ferrule abutting the ceramic insulator has first and second openings that house first and second metallic housings nesting respective coil springs. The metallic housings connected to the respective short and long terminal pins are axially aligned in the silicon insulator. A lead connector connected to a strain-relief for a lead supports a co-axial lead pin having electrically isolated center and circumferential outer conductors. When the lead connector/strain-relief subassembly is connected to the feedthrough, the center and circumferential conductors of the lead pin are electrically connected to the coil springs nested in the first and second metallic housings connected to the short and long terminal pins of the feedthrough.

Abstract: A case-neutral electrochemical cell has an electrode assembly comprising a separator positioned between an anode and a cathode housed inside a casing. The casing supports a co-axial glass-to-metal seal comprising an inner insulating glass hermetically sealed to a terminal pin and to the inner surface of a first or inner ferrule. An outer insulating glass is hermetically sealed to the outer surface of the inner ferrule and the inner surface of a second or outer ferrule, and the outer ferrule is secured to an opening in the casing. Then, one of the anode and the cathode is connected to the terminal pin and the other of the anode and the cathode is connected to the first or inner ferrule. An electrolyte is provided in the casing to activate the electrode assembly.

Abstract: A case-neutral electrochemical cell has an electrode assembly comprising a separator positioned between an anode and a cathode housed inside a casing. The casing supports a co-axial glass-to-metal seal comprising an inner insulating glass hermetically sealed to a terminal pin and to the inner annular surface of an inner ferrule. An outer insulating glass is hermetically sealed to the outer annular surface of the inner ferrule and the inner annular surface of an outer ferrule, and the outer ferrule is secured to an opening in the casing. Then, one of the anode and the cathode is connected to the terminal pin and the other of the anode and the cathole is connected to the first or inner ferrule.

Abstract: A miniature electrochemical cell of a primary or a secondary chemistry with a total volume that is less than 0.5 cc is described. The cell has a casing comprising an annular sidewall supported on a lower plate opposite an upper closure plate. The upper plate has a sealed electrolyte fill port. A current collector having an opening aligned with the fill port contacts an inner surface of the upper plate. An anode active material contacts the lower plate, and a cathode active material contacts the upper closure plate. A dielectric material coats the lower open end of the annular sidewall and a portion of the inner surface of the sidewall. A glass seals the dielectric material to the lower plate. An electrolyte contacts the electrode assembly. The cathode active material contacting the current collector has an opening aligned with the current collector opening and the electrolyte fill port.

Abstract: A miniature electrochemical cell of a primary or secondary chemistry with a total volume that is less than 0.5 cc is described. The cell has a casing comprising an annular sidewall supported on a lower plate opposite an upper lid. The lid has a sealed electrolyte fill port. At least one electrolyte channel in the inner surface of the lid extends radially from the fill port and outwardly beyond an outer peripheral edge of the current collector. A current collector contacts an inner surface of the lid with a first electrode active material contacting the current collector. An opposite polarity active material contacts the lower plate. A dielectric material coats the lower open end of the annular sidewall and a portion of the inner surface of the sidewall. A glass seals the dielectric material to the lower plate. An electrolyte activates the electrode assembly.

Abstract: An active implantable medical device (AIMD) assembly has a medical device housing containing an electrical power source connected to control circuitry, and a header assembly connected to the device housing. The header assembly supports a plurality of co-axially aligned terminal blocks that are in open communication with a header opening. A conventional strain relief member is connected to the header assembly at the header opening. A number of different auxiliary strain relief devices are described. The auxiliary strain relief devices connect to the conventional strain relief member to help reduce tension and stress on a lead after the AIMD assembly is implanted in a body and the lead electrodes are connected to body tissue.

Abstract: The high-voltage and/or high-frequency pulse dielectric breakdown strength (DBS) of an implantable medical device is increased by strategically positioning insulation materials on or adjacent to the external surfaces of a filter capacitor. Dielectric breakdown strength is further increased by adding polymeric or ceramic nanoscale metal oxide insulative powders to the insulation materials.

Abstract: An active medical device has a feedthrough with at least two terminal pins that are connected to electronic components in the device housing. A lead connector is connected to a strain-relief device for a lead. The lead connector supports at least two proximally-facing C-shaped inserts with an annular spring nested therein that are detachably connected to the device terminal pins to thereby connect the device electronic components to the lead electrodes. The device housing has a length extending along a longitudinal axis, and secondary axes of the terminal pins connected to the C-shaped inserts/annular springs are aligned parallel to the axis with imaginary extensions of the connector axes extending into the device housing.
