  • Patent number: 11147979
    Abstract: An implantable medical device (IMD) with an inductive coil for wireless communication and/or power transfer. The inductive coil may be disposed about a housing of the IMD. The housing may include a magnetically permeable material that is configured to operate as a flux concentrator for concentrating non-radiative near-field energy through the inductive coil. In some cases, the near-field energy may be captured and converted into electrical energy that may be used to recharge a rechargeable power source of the IMD.

  • Publication number: 20210308467
    Abstract: An implantable medical device (IMD) is configured with a pressure sensor. The IMD includes a housing and a diaphragm that is exposed to the environment outside of the housing. The diaphragm is configured to transmit a pressure from the environment outside of the housing to a piezoelectric membrane. In response, the piezoelectric membrane generates a voltage and/or a current, which is representative of a pressure change applied to the housing diaphragm. In some cases, only changes in pressure over time are used, not absolute or gauge pressures.

  • Publication number: 20210283409
    Abstract: Improved devices, circuits and methods of operation in implantable stimulus systems. An implantable defibrillator may comprise a charging circuit using a transformer to store and build up energy on an HV capacitor or capacitor stack, with the HV capacitor in turn coupled to an H-bridge output circuit having low and high sides for issuing therapy. In the output current path, a current controlling circuitry is placed between the H-bridge and ground, allowing the greater flexibility in the selection of switching devices, and drivers for such devices, in the H-bridge circuit and/or enabling circuits between the H-bridge and the HV capacitor or other therapy circuit.

  • Patent number: 11116988
    Abstract: Implantable medical devices such as leadless cardiac pacemakers may include a rechargeable power source. In some cases, a system may include an implanted device including a receiving antenna and an external transmitter that transmits radiofrequency energy that may be captured by the receiving antenna and then be converted into electrical energy that may be used to recharge a rechargeable power source. Accordingly, since the rechargeable power source does not have to maintain sufficient energy stores for the expected life of the implanted device, the power source itself and thus the implanted device, may be made smaller while still meeting device longevity expectations.
