Claim Text:
1. An implantable medical device comprising: an antenna configured to receive a far field radiative signal; a receiver coupled to the antenna, the receiver configured to receive therapy parameter data from an external source, the therapy parameter data including a charge threshold; 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; 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; and a threshold detector coupled to the charge storage element, wherein the threshold detector is configured to determine when the charge stored at the charge storage element satisfies the charge threshold and to provide an indication to the stimulation module when the charge threshold is satisfied, and wherein the stimulation module is operative to generate the electrical stimulation signal responsive to the indication.
