SYSTEMS AND METHODS FOR IMPLANTABLE LEADLESS BRAIN STIMULATION
First Claim
1. A method for stimulating brain tissue comprising:
- generating acoustic energy at a first implantation site;
receiving the acoustic energy at a brain stimulation site; and
converting the received acoustic energy into electrical brain stimulation energy based on energy and signal information included in the generated acoustic energy.

Abstract
Systems and methods are disclosed to stimulate brain tissue to treat medical conditions such as movement disorders, pain and epilepsy. The disclosed invention uses electrical stimulation of the brain tissue, 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 either implanted or located externally. The vibrational energy is received by a receiver-stimulator, which could be located under the skull, within the brain, on the dura, or in the cranial space close to the brain. As a therapeutic treatment, the implantable receiver-stimulator stimulates the brain sites that are effective in altering brain activity.
