FAR FIELD RADIATIVE POWERING OF IMPLANTABLE MEDICAL THERAPY DELIVERY DEVICES
First Claim
1. An implantable medical device comprising:
- an antenna configured to receive a far field radiative signal;
a voltage rectifier configured to rectify the far field radiative signal received by the antenna to provide a rectified voltage signal;
a charge storage element operative to receive the rectified voltage signal and to store charge responsive to the rectified voltage signal; and
a therapy delivery unit powered by the charge storage element, the therapy delivery unit operative to deliver a therapy to a patient.
