Patent ID: 8494644

Claim:
A system for bone stimulation therapy comprising: an implantable acoustic controller-transmitter, 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 wherein the one or more sensors are configured to detect an electrical stimulation output; and an implantable acoustic receiver-stimulator having an electrode assembly adapted to be in electrical communication with bone, wherein the controller-transmitter is adapted to transmit acoustic energy and the receiver-stimulator is adapted to receive acoustic energy and the controller-transmitter provides energy and signal information to the receiver-stimulator to provide electrical stimulation energy to bone; wherein the controller-transmitter is configured to sense the electrical stimulation energy using one or more of the sensors, and wherein the controller-transmitter is configured to adjust the transmitted acoustic energy to compensate for changes in the electrical stimulation energy.
