Abstract: A self-centering ceramic 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.

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 (GTMS) 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. The outer ferrule is secured to an opening in the casing. Two methods are described for manufacturing a co-axial GTMS depending on the melting temperatures of the inner and outer insulating glasses. 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 inner ferrule. An electrolyte is provided in the casing to activate the electrode assembly.

Abstract: In various examples, a header of an implantable device includes a first header portion and a second header portion at least partially disengageable from the first header portion. In a closed configuration, the first header portion is fully engaged with the second header portion, and in an open configuration, the first header portion is at least partially disengaged from the second header portion. At least one bore within the header is sized and shaped to accommodate a proximal end of a lead. The bore is split substantially longitudinally to form a first bore portion and a second bore portion. With the proximal end of the lead disposed within the bore and a positioning feature interacting with a lead feature, at least one lead contact aligns with at least one header contact to allow the at least one lead contact to electrically couple to the at least one header contact.

Abstract: An AIMD includes a ceramic base closed with a ceramic lid, both cooperatively separating body fluid and device sides. The lid and circuit board both have active and conductive pathways. A circuit board has active and ground conductive pathways. An anisotropic conductive layer disposed between the lid device side and the circuit board has a first thickness where a first conductive particle is in electrical contact with the lid and the circuit board active conductive pathways electrically connected to the active terminal of an electronic component on the circuit board, a second thickness where a second conductive particle is in electrical contact with the lid and the circuit board ground conductive pathways electrically connected to the ground terminal of the electronic component. The anisotropic conductive layer has a third, greater thickness where no conductive particles are in electrical contact with the lid and circuit board conductive active and ground pathways.

Abstract: 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.

Abstract: 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.
