摘要： The present invention changes the magnet-mode of an active implantable medical device (AIMD) using a static strip magnet comprising at least a first, second and third magnet. The electronic circuits of the AIMD have been programmed to register when the static strip magnet has been swiped across the AIMD so that when the magnetic field-detection sensor detects a defined north and south polarity sequence of the first, second and third magnets, the electronic circuits have been programmed to enter into magnet-mode with electrical stimulation therapy of the body tissue and/or electrical sensing of biological signals from the body tissue being suspended, maintained in a preset mode, or placed in a programmed mode.

摘要： A feedthrough terminal pin connector assembly for an active implantable medical device (AIMD) includes first and second terminal pin connectors, each comprising a sidewall having an exterior surface spaced from an interior surface defining a connector opening extending along a longitudinal axis. At least a first portion of the sidewall is electrically conductive. An electrically conductive compliant structure is supported by the electrically conductive portion of the sidewall in each of the first and second connector openings. A common housing contains the first and second terminal pin connectors with an insulative material electrically isolating the first and second electrically conductive sidewall portions from each other. The common housing is configured to be supported on a circuit board having at least a first and a second electrical circuits with the first and second electrically conductive portions being electrically connected to the respective first and second electrical circuits.

摘要： 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.

摘要： A self-centering washer is positioned between the feedthrough and filter capacitor of a filtered feedthrough. 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.

摘要： In various examples, a component is for use in an implantable medical device. The component includes a pin including a first material attached to a lead including a second material different from the first material of the pin. At least a portion of the lead includes a channel in which at least a portion of the pin sits, the channel including a channel opening defined at least partially by opposing first and second channel sides extending a channel length. At least a first joint is formed along at least a portion of the first channel side. The first joint includes the second material of the lead deformed to at least partially close the channel opening to retain the pin within the channel to attach the lead to the pin. In some examples, the first material includes molybdenum and the second material includes aluminum.

摘要： A pulse dischargeable electrochemical cell, preferably of a Li/SVO couple, is described. To help prevent lithium clusters from bridging to the terminal pin extending below the casing lid and connected to the cathode current collector tab, an elastomeric gasket directly contacts the inner surface of the lid. The elastomeric gasket is preferably a unitary member comprising an O-ring gasket portion that contacts the sealing glass of the glass-to-metal seal (GTMS), and a sheet-shaped gasket portion connected to the O-ring gasket portion and that contacts the inner surface of the lid. The GTMS does not have a ferrule. Instead, the sealing glass seals directly to the lid and to the terminal pin. The elastomeric gasket resides between the lid and an insulator compartment, which is described in co-assigned U.S. Pat. No. 10,629,862 to Roy et al.

摘要： 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.

摘要： An electrical power source comprises a casing made by diffusion bonding an intermediate ceramic ring to a titanium base plate and a titanium top ring. An anode housed in the resulting open-ended container is electrically connected to the base plate. A separator is positioned on the anode. Separately, a cathode is electrically connected to a titanium lid. The lid fitted on the titanium top ring opposite the intermediate ceramic ring is welded to the top ring to close the casing. An electrolyte filled into the casing through a fill port in the lid activates the anode/cathode assembly. The fill port is then hermetically sealed. Gold pads are individually contacted to the base plate and the lid, which serve as opposite polarity terminals for the power source.
