Abstract: A lithium-iodine cell comprising a cathode including a charge transfer complex of an organic donor component and iodine, an anode including a lithium element having a surface operatively contacting the charge transfer complex material, and a coating on the lithium surface of an organic electron donor material, preferably but not necessarily the organic donor component of the charge transfer complex. The organic electron donor material preferably comprises polyvinyl pyridine polymer and in particular two-vinyl pyridine polymer. A solution of two-vinyl pyridine polymer in benzene is brushed onto the anode lithium surface and then exposed to a desiccant. A number of coatings preferably are applied successively to provide a resulting or finished coating of increased thickness.

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.

Abstract: A self-centering 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 polymeric film cover assembly for isolating an electrochemical power source from the other components housed inside an implantable medical device is described. The cover assembly comprises a first shallow-formed shaped-cover of a polymeric film configured to cover a first portion of the exterior surface of the casing and a second shallow-formed shaped-cover of the polymeric film configured to cover a second portion of the exterior surface of the casing. With the first and second shaped-covers contacting the casing, the shaped-covers are connected to each other in an overlapping or butted relationship to substantially or completely cover the exterior surface area of the casing. The interlocking polyester shaped-covers are readily formable into the desired three-dimensional form factor of the casing of power source while maintaining a desirable film thinness.

Abstract: A ceramic reinforced metal composite (CRMC) comprising a composition composite as an interpenetrating network of at least two interconnected composites is described. The interpenetrating networks comprise a ceramic matrix composite (CMC) and a metal matrix composite (MMC). The composition composite is particularly useful as an electrically conductive pathway extending through the insulator or ceramic body of a hermetically sealed component, for example, a feedthrough in an active implantable medical device (AIMD).

Abstract: A hermetic feedthrough terminal pin connector for an active implantable medical device (AIMD) includes an electrical insulator hermetically sealed to an opening of an electrically conductive ferrule. A feedthrough terminal pin is hermetically sealed to and disposed through the insulator, the feedthrough terminal pin extending outwardly beyond the insulator on the inside of the casing of the AIMD. A circuit board is disposed on the inside of the casing of the AIMD. A terminal pin connector includes: an electrically conductive connector housing disposed on the circuit board, wherein the connector housing is electrically connected to at least one electrical circuit disposed on the circuit board; and at least one electrically conductive prong supported by the connector housing, the at least one prong contacting and compressed against the feedthrough terminal pin, the at least one prong making a removable electrical connection.

Abstract: A method for manufacturing a ceramic substrate by a 3D-printing process is described. The method comprises operating a 3D-printer to print a green-state ceramic body having a height extending to spaced apart first and second end surfaces and at least one via extending at least part-way along the height of the green-state ceramic body from the first end surface toward the second end surface. Then, the green-state ceramic body is sintered to provide the ceramic substrate with the at least one via. In cross-section, the at least one via has a square-shaped via with rounded corners.

Abstract: In various examples, a method of making a guidewire is described. The method includes placing a polymer jacket over a core wire. The core wire includes a first portion having a first profile and a second portion having a second profile. The first profile is smaller than the second profile. Heat is applied to the polymer jacket and the core wire to reflow the polymer jacket and fuse the polymer jacket to the core wire, wherein the polymer jacket forms a layer of substantially uniform thickness along a length of the core wire. In some examples, a guidewire made using the method is also described.

Abstract: In various examples, an apparatus is configured for subcutaneously inserting an implantable device within a patient. The apparatus includes a dilator portion including a dilator including a dilator length. The dilator portion is configured to separate tissue to create a subcutaneous pocket within the patient sized and shaped to accommodate an implantable device within the subcutaneous pocket. A sheath portion includes a sheath sized and shaped to accommodate the dilator within a sheath lumen. The sheath is configured to accommodate an antenna of the implantable device with the dilator removed from within the sheath. The sheath includes a sheath length that is at least substantially as long as an antenna length. The sheath is configured to separate to allow removal of the sheath around the implantable device to remove the sheath from and leave the implantable device within the subcutaneous pocket within the patient.
