Abstract:
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; a stimulation module powered by the charge storage element, the stimulation module operative to generate an electrical stimulation signal to stimulate a target nerve of a patient; control circuitry configured to modulate backscattered energy to encode data in a third order frequency harmonic component of energy backscattered from the implantable medical device; and a nerve wrap configured to house the voltage rectifier, the charge storage element, and the stimulation module, wherein the nerve wrap includes one or more electrodes operative to deliver the electrical stimulation signal to the target nerve.
