Abstract
A system for use in stimulating bone growth, tissue healing, and/or pain control is described. The system includes a screw, a battery, a controller, and means for connecting the battery such that current is routed from the battery through the screw and thence to a target area of interest requiring treatment. The screw includes an elongate shaft having a length extending between opposite ends. The shaft has an insulating coating extending along at least a portion of the length. The thickness of the insulating coating at various portions of the shaft is modulated to optimally direct current to a target area of interest requiring treatment. The controller adjusts the duty cycle of the current flow over the treatment period.
