Abstract
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 stimulation module powered by the charge storage element. The stimulation module may be operative to generate an electrical stimulation signal to stimulate a target nerve of a patient. The implantable medical device may further include a nerve wrap configured to house the voltage rectifier, the charge storage element, and the stimulation module. The nerve wrap may include one or more electrodes operative to deliver the electrical stimulation signal to the target nerve.
