Deep Brain Simulation (DBS) is a well-accepted technique for ameolerating symptoms for a range of neurological diseases and disorders. Today\u27s circular electrode contacts on the implanted leads creates an electronic current flow outwards in a circular from the cathode ring to an adjacent anode ring on the same lead. If the lead is misplaced outside the target site then stimulation is highly inefficient and potentially fraught with side effects because only part of the current flow hits the target and most of the flow goes elsewhere in the brain. A novel approach disclosed herein is to electronically draw current flow in the desired direction the target area.Benefits include improved symptom control for existing DBS patents without the need for additional brain surgery
