Claim Text:
1. A system for stimulating tissue comprising: an acoustic controller-transmitter; and an implantable acoustic receiver-stimulator having an electrode assembly adapted to be in direct contact with the tissue and one or more sensors disposed on an external surface of the housing, wherein the controller-transmitter is adapted to transmit acoustic energy and the receiver-stimulator is adapted to receive acoustic energy and convert it to electrical energy, and the controller-transmitter provides energy and signal information to the receiver-stimulator to provide electrical stimulation to the tissue; wherein the controller-transmitter is configured to periodically sense the electrical stimulation output of the receiver-stimulator using one or more of the sensors and adjust acoustic energy transmission from the receiver-stimulator accordingly in order to compensate for charges in the electrical stimulation output of the receiver-stimulator.
