Systems and methods for implantable leadless bone stimulation
First Claim
1. A method for bone stimulation therapy comprising:
- implanting a bone attachment device at a bone healing site, wherein a receiver-stimulator is housed within the bone attachment device;
generating acoustic energy using a controller-transmitter, wherein the controller-transmitter comprises one or more sensors;
receiving the acoustic energy by means of the receiver stimulator;
converting the received acoustic energy into electrical bone stimulation energy using the receiver stimulator based on energy and signal information included in the generated acoustic energy;
wherein the bone attachment device comprises one or more stimulation electrodes connected to the receiver stimulator, such that the stimulation electrodes lie in electrical communication with the bone healing site, and the bone healing site is chosen to treat for bone regrowth, bone repair, fusion of bones, or fusion of bone grafts;
delivering the electrical bone stimulation energy to the bone healing site using the one or more stimulation electrodes;
sensing the electrical bone stimulation energy, wherein the sensors are adapted to sense the electrical bone stimulation energy; and
adjusting the acoustic energy generated by the controller-transmitter to compensate for changes in the electrical bone stimulation 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.
