Systems and methods for implantable leadless gastrointestinal tissue stimulation
First Claim
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.

Abstract
Systems and methods are disclosed to stimulate gastrointestinal tissue to treat medical conditions such as eating disorders, gastroparesis, and gastric reflux. The invention uses electrical stimulation of the nerve, where vibrational energy from a source is received by an implanted device and converted to electrical energy and the converted electrical energy is used by implanted electrodes to stimulate the pre-determined gastrointestinal tissue site. The vibrational energy is generated by a controller-transmitter, which could be implanted or located externally. The vibrational energy is received by a receiver-stimulator, which could be located in the various regions on or around the gastrointestinal tissue that needs to be stimulated. The implantable receiver-stimulator stimulates different gastrointestinal tissue to provide the desired therapeutic benefit.
