Abstract:
1. A system for gastrointestinal tissue 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 wherein the one or more sensors are configured to detect an electrical stimulation output and wherein the acoustic energy contains both energy and signal information; and an implantable acoustic receiver-stimulator having a stimulation electrode assembly adapted to be in direct contact with gastrointestinal tissue, wherein the receiver-stimulator is configured to receive and convert the acoustic energy into the electrical stimulation output delivered to the gastrointestinal tissue by the stimulation electrode assembly; 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 energy transmission accordingly in order to compensate for changes in electrical stimulation output of the receiver-stimulator.
