Systems and methods for implantable leadless bone stimulation

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.
