System and method to alter bone growth in a targeted spatial region for the purpose of use with implants

A system for altering bone growth on and within an orthopedic implant comprising:

• an implant body, wherein the implant body comprises an exterior surface and an interior surface defining an internal cavity of the implant body;
• a plurality of electrodes, wherein each electrode is at least partially embedded in the implant body, and comprises:
• a set of primary electrodes comprising at least one electrode, wherein a non-embedded segment of each primary electrode is proximal to a bone growth region including at least the defined internal cavity,
• a set of secondary electrodes comprising at least one electrode, wherein a non-embedded segment of each secondary electrode is distal to the bone growth region, and
• wherein the plurality of electrodes are configured to function in a stimulation operating mode, such that a subset of primary electrodes function as cathodes and a subset of secondary electrodes function as anodes;
• a control system comprising a processor, and circuitry that connects to the plurality of electrodes,
• wherein the processor comprises machine instructions configured to control direction and magnitude of current traveling through each electrode from the plurality of electrodes;
• and
• a power system comprising a power source and circuitry that provides electrical power for function of the plurality of electrodes.
