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: 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 connector pins 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 connector pins are aligned parallel to the longitudinal axis. The feedthrough also has spaced-apart distally extending arms with detents, and the lead connector has spaced-apart lateral recesses. With the detents of the feedthrough arms received in the lateral recesses of the lead connector, the medical device is detachably connected to the strain-relief device and the lead.

Abstract: An inductive charging antenna for charging the power source of an active implantable medical device (AIMD) is described. The charging antenna is supported on the body fluid side of the feedthrough insulator, on the device side of the insulator or it is embedded inside the insulator. The charging antenna is connected to electronic circuits housed inside the medical device to charge the power source so that the device can deliver electrical stimulation to a patient and receive sensed biological signals from body tissue, among other functionalities. If the charging antenna is supported on the insulator body fluid side, it is made from a biocompatible material such as platinum. However, if the charging antenna is embedded inside the feedthrough insulator or is supported on the device side of the insulator, it can be made from a less expensive material that is not biocompatible, for example, copper.

Abstract: A cable assembly for a patient treatment system comprises an electrical cable having a proximal connector configured to connect to an external electrical stimulator device and a distal connector including a distal housing having an open distal end. The distal housing houses a manifold that supports a plurality of spring-loaded electrical contact assemblies aligned in two rows and being electrically connected to a corresponding one of a plurality of electrical contacts in the proximal connector. The housing distal open end is closed by a header that is movable between a closed position resting on the housing open end and an open position spaced there above. The header has a pair of side-by-side longitudinally extending openings. With the header in the open position, a practitioner holds the distal connector in one hand and with the other hand inserts the distal electrical contacts of one or two therapy delivery devices into the longitudinally extending openings. The practitioner then moves the header into the closed position to bring the distal electrical contacts of the therapy delivery devices into firm electrical contact with the spring-loaded electrical contact assemblies housed inside the distal housing.

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: 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.

Abstract: An active implantable medical device (AIMD) has an alumina housing supporting at least two electrodes. A printed circuit board (PCB) assembly resides inside the housing. Two sintered platinum-containing pathways extend through the housing thickness from the electrodes supported on the housing body fluid side surface to a housing device side surface. A device side end of each of the two platinum-containing pathways is in electrical continuity with an electrical contact supported on the PCB to energize the electrodes for providing stimulation therapy to a patient or for sensing biological signals from the patient.
