This invention relates to an apparatus and method for making such apparatus for providing controlled and directional stimulation patterns for tissue stimulation. The apparatus may be useful in stimulation nervous tissue in the brain, about the spinal cord, on nerve roots, about peripheral nerves, and in muscles, among others. The apparatus includes a implantable pulse generator connected to a lead. The lead has electrodes placed about a perimeter. In addition, the lead may include electrodes placed longitudinally along the axis of the lead. By applying charge differences between circumferentially distributed electrodes, a smaller stimulation field may be established. In addition, by stimulating between electrodes distributed longitudinally on the same side, a directional flow field may be established. Such leads are especially useful in deep brain stimulation as the region in which a stimulation field is strong enough to produce tissue stimulation is directional and minimized.
