SYSTEMS AND METHODS FOR IMPLANTABLE LEADLESS SPINE STIMULATION
First Claim
1. A system for stimulating the spinal cord, said system comprising:
- an acoustic controller-transmitter configured to generate acoustic energy; and
an implantable acoustic receiver-stimulator having a stimulation electrode assembly adapted to be in direct contact with epidural tissue, wherein the receiver-stimulator is configured to receive and convert the acoustic energy into an electrical stimulation output delivered to the epidural tissue by the stimulation electrode assembly;
wherein the controller-transmitter is configured to sense the electrical stimulation output of the receiver-stimulator 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 spine tissue to treat medical conditions such as pain and spinal injury. The invention uses electrical stimulation of the spine, 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 brain site. The vibrational energy is generated by a controller-transmitter, which could be located either externally or implanted. The vibrational energy is received by a receiver-stimulator, which could be located in the various regions on around the spine. The implantable receiver-stimulator stimulates different locations in the spine region to provide therapeutic benefit.
