  • Publication number: 20150165196
    Abstract: An implantable medical device includes two conductive enclosures that are attached together, wherein the first enclosure contains electronics, and the second enclosure contains a power source. The second enclosure, all or a portion of which is located outside the first enclosure, includes an inner layer, an outer layer, and a header plate, all of which are configured to provide redundant sealing for the power source. The inner and outer layers, formed by separate metal sheets nested one within the other, are preferably in direct mechanical and electrical contact. The first sheet, which forms the inner layer, approximately conforms to a profile of the power source, located therein, and the second sheet, which forms the outer layer, conforms to a profile of the first sheet. An insulative housing, which contains connector contacts of the device, is directly secured to the first and second conductive enclosures, for example, by mounting brackets.

  • Patent number: 8682451
    Abstract: A lead system has an elongate body, an active fixation assembly movable relative to the elongate lead body, including a non-stationary electrode. The lead system further includes a non-stationary electrode member and an electrical interconnect electrically connected between the non-stationary electrode member and the stationary electrode member. The electrical interconnect provides a reliable electrical interconnection between the stationary electrode and the non-stationary electrode, while allowing the non-stationary electrode to move relative to the stationary electrode.

  • Publication number: 20120215296
    Abstract: This application discusses, among other things, a header assembly for coupling a medical electrical lead to a medical stimulating device including a header having a capture mechanism within a bore of a lead retention device. In an example, when the lead retention device is retracted from the bore, the capture mechanism prevents the device from falling out. In another example, the header assembly has a vent disposed within the bore of the lead retention device that permits unrestricted flow of air when the lead retention device is retracted from an engagement surface.

  • Patent number: 8032221
    Abstract: This application discusses, among other things, an implantable medical device including a setscrew that enables lead tip visibility as an indicator of full lead insertion without requiring a grommet. In an example, the implantable medical device header is provided with a lead bore and a setscrew bore with the setscrew bore having a longitudinal axis that extends in a transverse direction to, and in communication with, the lead bore. In one example, the setscrew bore intersects with the lead bore at a location that is offset from the central longitudinal axis of the lead bore.

  • Publication number: 20100249871
    Abstract: This application discusses, among other things, an implantable medical device including a setscrew that enables lead tip visibility as an indicator of full lead insertion without requiring a grommet. An example setscrew has a metal core with an insulative coating disposed over the core to electrically isolate it from body fluids and surrounding tissue. In another example, the setscrew incorporates a sealing capability by including a sealing member that is coupled to the setscrew.
