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.
