    Abstract: Implantable medical devices have modular lead bores that are constructed from individual lead bore modules. A given modular lead bore utilizes the number of individual lead bore modules necessary for the particular implantable medical device. Each lead bore module has a lead bore passageway and a feedthrough passageway. An electrical contact is present within the lead bore passageway of each lead bore module and the electrical contact is aligned to the lead bore passageway of a lead bore module. Hermetic feedthrough assemblies are also present within the lead bore passageway of each lead bore module. A feedthrough pin passes through a hermetic feedthrough assembly within a feedthrough passageway of each lead bore module. Each feedthrough pin is electrically coupled to a corresponding electrical contact and the medical device circuitry.

    Abstract: Medical devices provide metallic connector enclosures. The metallic connector enclosures may be constructed with relatively thin walls in comparison to polymer connector enclosures to aid in miniaturizing the medical device. The metallic connector enclosures may be constructed with interior surfaces that deviate less from an ideal inner surface shape in comparison to polymer connector enclosures to allow for better concentricity of electrical connectors. The metallic connector enclosures may include a panel that allows access to the cavity of the connector enclosure where set screw blocks, lead connectors, spacers, seals, and the like may be located. Furthermore, the lead connectors within the metallic connector enclosures may be separated from the metallic connector enclosure by being positioned within non-conductive seals that reside within features included in cavity walls of the connector enclosure. Similarly, set screw blocks may be separated from the metallic connector enclosure by non-conductive spacers present within the cavity.

    Abstract: Implantable medical devices include header structures with conductive paths from the feedthrough conductors that may be located on one side of the device to electrical connectors that may be located on an opposite side of the device. The conductive paths may include conductive interconnect pins and lead frame conductors. The conductive interconnect pins may be located in holes present in a header body where the conductive interconnect pins are attached to the feedthrough conductors on one end and are attached to the lead frame conductors on the opposite end. The lead frame conductors then extend to the corresponding electrical connectors. The header body may provide cavities on each side to allow for the insertion of stack assemblies that include the electrical connectors and lead frame conductors.

    Abstract: Medical devices provide connector enclosures that have a metallic portion that has a metallic weld to a metallic portion of a can that houses medical circuitry. The connector enclosure may have a metallic base that receives the metallic weld to the can. The can may have an open top that is capped by the metallic base of the connector enclosure upon mounting the connector enclosure to the can, and the metallic weld to the base of the connector enclosure may create a hermetic seal for the can. The metallic base may provide feedthrough pin passageways where feedthrough pins are present within the connector enclosure and are exposed beyond the metallic base for connection to medical circuitry within the can. The connector enclosure may also include additional metal features where an enclosure for the lead connectors may have walls that are entirely metal.

    Abstract: Seals used within lead passageways of implantable medical devices for creating a seal to implantable medical leads inserted into the lead passageways include a body defining a lead passageway with an axial dimension. The body further defines a first circumferential protrusion extending radially a first distance into the lead passageway, and the body further defines a second circumferential protrusion separated from the first circumferential protrusion along the axial dimension. The second circumferential protrusion extends radially a second distance into the lead passageway, the second distance being less than the first distance. The body further defines a first circumferential depression immediately adjacent the first circumferential protrusion and between the first circumferential protrusion and the second circumferential protrusion.
