  • Patent number: 11980766
    Abstract: 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.

    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.

  • Patent number: 11904284
    Abstract: A hollow expansion chamber of the present invention is configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, where a chamber body of the expansion chamber has a rounded shape. When moving circumferentially downward along the chamber body starting from a maximum inside diameter, the rounded shape of a bottom portion has a first integral transition that is a tangential transition to a first frustoconical shape. Continuing moving circumferentially downward, the first frustoconical shape has a second integral transition to a cylindrical extension. The cylindrical extension at a distal end has a bottom opening configured to fit within an opened bottleneck. The first frustoconical shape has a minimum angle of 15 degrees relative to a horizontal plane. The second integral transition is a radial second integral transition having an inside surface radius of at least 0.25 inches.

  • Publication number: 20240039206
    Abstract: A circuit board for an active implantable medical device (AIMD) has a circuit board land connected to at least one electrical circuit. A hermetic feedthrough terminal pin connector for the AIMD includes an electrical insulator hermetically sealed to an opening of an electrically conductive ferrule. A terminal pin of the feedthrough extends outwardly beyond the insulator. A terminal pin connector has an electrically conductive connector housing that is connected to the circuit board land by an electrical connection material. At least one electrically conductive prong supported by the connector housing contacts and compresses against the feedthrough terminal pin to thereby make a removable electrical connection between the circuit board and the terminal pin. An insulative material loaded with electrically insulative nanoparticles coats at least a portion of the sidewall of the connector housing and the electrical connection material connecting the connector housing to the circuit board land.

  • Publication number: 20230166115
    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.

  • Patent number: 11648409
    Abstract: An EMI/energy dissipating filter for an active implantable medical device (AIMD) comprises a first gold braze sealing an insulator to the ferrule of a glass-to-metal seal (GTMS) and a lead wire that is sealed in a passageway through the insulator by a second gold braze. A circuit board is disposed adjacent to the insulator. A two-terminal chip capacitor disposed adjacent to the circuit board has an active end metallization connected to its active electrode plates and a ground end metallization connected to its ground electrode plates. A ground electrical path extends from the ground end metallization of the chip capacitor, through a circuit board ground plate disposed on or within the circuit board, and to the ferrule. An active electrical path extends from the active end metallization of the chip capacitor to the lead wire of the GTMS.

  • Publication number: 20230135610
    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.

  • Patent number: 11571580
    Abstract: The present invention changes the magnet-mode of an active implantable medical device (AIMD) such that repeated application of a clinical magnet in a predetermined and deliberate time sequence will induce the AIMD to enter into its designed magnet-mode. In one embodiment, a clinical magnet is applied close to and over the AIMD and removed a specified number of times within a specified timing sequence. In another embodiment, the clinical magnet is applied close to and over the AIMD and flipped a specified number of times within a specified timing sequence. This makes it highly unlikely that the magnet in a portable electronic device, children's toy, and the like can inadvertently and dangerously induce AIMD magnet-mode.
