Title
(EN) Far field radiative powering of implantable medical therapy delivery devices
Abstract
(EN)
A particular implantable device may include an antenna configured to receive a far field radiative signal. The implantable device may also include a voltage rectifier configured to rectify the far field radiative signal received by the antenna to provide a rectified voltage signal. The implantable device may further include a charge storage element operative to receive the rectified voltage signal and to store charge responsive to the rectified voltage signal. The implantable device may also include a therapy delivery unit powered by the charge storage element. The therapy delivery unit is operative to deliver a therapy to a patient.
