  • Publication number: 20190209848
    Abstract: An implantable medical device (IMD) may include a plurality of coils that may be used to recharge a power supply of the IMD and/or provide telemetry for the IMD. The IMD may be configured to couple all of the coils in series, such that currents that are induced by each of the coils are added together when the IMD is exposed to an electromagnetic field. The IMD may be configured to alter the coupling of the coils such that the coils are coupled in series opposition, such that currents that are induced by some coils of the IMD are opposed by currents that are induced by other coils of the IMD.

  • Patent number: 9220902
    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.
