Abstract: An implantable medical device includes an enclosure sleeve and a top cap. The enclosure sleeve comprises an enclosure wall with at least a portion of the enclosure wall comprising the grade 5 titanium and having a thickness between 0.007 inches and 0.009 inches. The enclosure sleeve includes an open top end and an open bottom end that is opposite the open top end. The top cap includes a feedthrough block, a first top cap end portion, and a second top cap end portion. The first top cap end portion is configured to couple to the open top end of the enclosure sleeve, and the second top cap end portion configured to be positioned within the enclosure sleeve.

Abstract: Seals used within lead bores of implantable medical devices for creating a seal to implantable medical leads inserted into the lead bores include an inner cylinder that engages the lead body. The inner cylinder is surrounded by a gap to either an outer cylinder of the seal or to surrounding structures of the implantable medical device. The inner cylinder has freedom of movement within the gap such that movement of the lead body that is off-axis relative to a centerline of the lead bore causes movement of the inner cylinder that is providing the seal. In this manner, the seal engagement to the lead body is maintained during this off-axis movement of the lead body.

Abstract: Connector enclosure assemblies for medical devices provide an angled lead passageway. The lead passageway which is defined by electrical connectors and intervening seals within the connector enclosure assembly establishes the angle relative to a base plane of the connector enclosure assembly. Various other aspects may be included in conjunction with the angled lead passageway, including an angled housing of the connector enclosure assembly, feedthrough pins that extend to the electrical connectors where the feedthrough pins may include angled sections, and a set screw passageway set at an angle relative to the lead passageway to provide fixation of a lead within the lead passageway.

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 connector enclosure assemblies that utilize conductors that are electrically coupled to feedthrough pins and that extend into a can where electrical circuitry is housed. The conductors may be coupled to the feedthrough pins and to capacitor plates within a filter capacitor by an electrically conductive bonding material and as a single bonding event during manufacturing. The base plate of the connector enclosure assembly may also include a ground pin. Ground capacitor plates may be present at a ground aperture of the filter capacitor where the ground pin passes through so that the ground pin, a ground conductor, and the ground capacitor plate may be coupled. A protective cover may be provided for the connector enclosure assembly to enclose the conductors intended to extend into the can prior to the assembly being joined to the can. Conductors may be attached to a common tab that is subsequently removed.

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.

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.
