摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Implantable medical devices include an enclosure that is constructed by machining of a material rather than by forming or stamping. The machining produces one or more internal features within the enclosure. These internal features may include shelves that may act as a stiffener and create separate compartments within the enclosure. These internal features may include contoured edges along the shelves to accommodate conductors and other structures that extend from one compartment to another. These features may include slots that are present in one or more locations, such as on a surface of one of the shelves. These internal features may also include standoffs that establish a gap between an internal component and the external wall of the enclosure. These internal features may also include different thicknesses in different areas of the enclosure, such as one wall thickness in one compartment and a different wall thickness in another compartment.

摘要： Enclosures for implantable medical devices are machined from biocompatible materials using processes such as electric discharge machining and/or milling. Material is machined to create an enclosure. The enclosure may include an enclosure sleeve that has top and bottom caps added where the enclosure sleeve is machined either as a whole or as two separate halves that are subsequently joined together. During construction, circuitry is installed and where the enclosure includes an enclosure sleeve, the open top and bottom may be closed by caps while a connector block module may be mounted to the complete enclosure. The machining process allows materials that are typically difficult to stamp, such as grade 5 and 9 titanium and 811 titanium, that are beneficial to telemetry and recharging features of an implantable medical device to be used while allowing for an enclosure with a relatively detailed geometry and relatively tight tolerances.
