  • Patent number: 10639486
    Abstract: Implantable medical device (IMD) such as leadless cardiac pacemakers may include a rechargeable power source. In some cases, the IMD may include a plurality of receiving coils that may capture a non-radiative near-field energy and then convert the near-field energy into electrical energy that may be used to recharge the rechargeable power source. Accordingly, since the rechargeable power source does not have to maintain sufficient energy stores in a single charge for the entire expected life of the IMD, the power source itself and thus the IMD, may be made smaller while still meeting device longevity expectations.
