Patent ID: 8494643

Claim:
A system for nerve stimulation therapy, said system comprising: an acoustic controller-transmitter configured to transmit acoustic energy, wherein the controller-transmitter comprises acoustic transducers disposed in a housing and one or more sensors disposed on an external surface of the housing; and an implantable acoustic receiver-stimulator having a stimulation electrode assembly adapted to be in direct contact with nerve, wherein the receiver-stimulator is configured to receive and convert the acoustic energy into an electrical stimulation output delivered to the nerve by the stimulation electrode assembly, wherein the electrical stimulation output has at least one of pulse amplitude, pulse duration, duty cycle, and timing based on energy and signal information included in the generated acoustic energy; wherein the controller-transmitter is configured to sense the electrical stimulation output of the receiver-stimulator using one or more of the sensors and adjust acoustic energy transmission from the controller-transmitter accordingly in order to compensate for changes in electrical stimulation output of the receiver-stimulator.
