Abstract
Stimulation current is steered further outward and/or inward from a plane of the stimulating electrodes by using one or more steering currents. The steering current may be used to occupy space in the tissue where stimulation is not desired and to force the stimulation current to pass through target tissue. The steering current may be present in various locations such as in tissue that is immediately adjacent the plane of the electrodes to force the stimulation current away from the immediately adjacent area and deeper into surrounding target tissue. The steering current may be present in tissue that is beyond the target tissue to confine the outward reach of the stimulation current to that target tissue. The stimulation current may be produced by one power source while the steering current may be produced by one or more other power sources, each of the power sources being unreferenced to each other.
