Implantable medical devices such as leadless cardiac pacemakers may include a rechargeable battery, and a receiving antenna for receiving radiative energy from an external transmitter. Energy captured by the receiving antenna of the implantable medical device may be converted into electrical energy that may be used to recharge the rechargeable battery of the implantable medical device. Since the rechargeable battery does not have to initially store sufficient energy to power the implantable medical device over its entire useful life, the battery itself and thus the implanted medical device can be made smaller while still achieving device longevity expectations.

Devices and methods for wirelessly recharging a rechargeable battery of an implantable medical device

An electrode stimulation delivery system is described having a unit and a network of wireless remote electrodes configured for implantation within a plurality of spaced apart locations in the tissue, e.g. myocardium, of a patient. The control unit is configured to be positioned at or subcutaneous to the patient's skin, and includes a processor, an antenna configured for delivering RF energy in proximity to the plurality of wireless remote electrodes, and programming executable on the processor for wirelessly communicating to the network of wireless remote electrodes via the delivered RF energy to individually control pacing of the plurality of wireless remote electrodes. Each of the plurality of wireless remote electrodes comprises a metamaterial-based biomimetic harvesting antenna comprising a Van Atta array zero-phase transmission lines to receive the RF energy to power activation of the plurality of wireless remote electrodes.
