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

Abstract
Systems and methods are disclosed to enhance bone growth by stimulating bone sites for bone regrowth, fusion, or grafts. The invention uses electrical stimulation of the bone site, 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 bone 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-transmitter, which could be incorporated into an orthopedic device, such as pin, cage, plate or prosthetic joint used for bone healing.

31. A method for bone stimulation therapy comprising:
-
generating acoustic energy using a controller-transmitter; receiving the acoustic energy at a bone stimulation site by means of an implanted receiver-stimulator; converting the received acoustic energy into electrical bone stimulation energy based on energy and signal information included in the generated acoustic energy, operating the controller-transmitter such that electrical bone stimulation energy is generated by the receiver-stimulator at the predetermined bone stimulation site; wherein the receiver-stimulator comprises one or more stimulation electrodes, such that the stimulation electrodes lie in electrical communication with the predetermined bone stimulation site, and the predetermined bone stimulation site is chosen to treat for bone regrowth, bone repair, fusion of bones, or fusion of bone grafts.
