Abstract:
1. A system comprising: a control unit configured with an antenna sized and shaped to produce a magnetic field; and an implantable wireless batteryless electrostimulation electrode assembly configured (1) to receive magnetic energy from the magnetic field, (2) to directly convert the received magnetic energy into a specified tissue electrostimulation waveform without storing the received energy in a discrete capacitive storage device and without storing the received energy in an electrochemical storage device, (3) to be implanted from within a heart chamber into a heart chamber inner wall tissue site and to deliver the tissue electrostimulation waveform to the heart chamber inner wall tissue site in response to the magnetic field, and (4) to inhibit the delivery of the tissue electrostimulation waveform in response to the absence of the magnetic field.
