Methods for electronic directionality of deep-brain stimulation
First Claim
1. A deep brain stimulation system comprising:
- an implanted electrode member having plural independently controllable cathode contacts and plural independently controllable anode contacts, the electrode member being selected from at least one of an implanted electrode lead or separately implanted plate or separately implanted contact;
at least one implantable pulse generator for controlling the implanted electrode member to independently generate an electric field from one or more electrode cathode contacts and draw a current from the generated electric field toward one or more electrode anode contacts through a targeted area; and
a connection between the implanted electrode member and the implantable pulse generator.

Abstract
Methods, systems and devices to provide correction parameters for implanted electrodes by applying a cathode pulse to a bilateral implanted electrode while providing a synchronized anode on the opposite electrode. The electrical field can be “shaped” over space and time to reach more of the targeted area by selecting various combinations of active contacts. The cathode lead directs the electrical field to the target and the placement and number of anode contacts activated determines the electric field path and rate of dissipation based on vertical and horizontal distance and timing. The correction parameter can be applied to anode and cathode contacts on a single implanted lead. Each lead can have plural anode and cathode contacts each independently controllable. Active anodes and cathodes are statically or dynamically selected to generate a shaped electric field to reach the target.

17. A method for delivering a stimulation current to a targeted area of a brain with a deep brain stimulation pulse generator comprising the steps of:
-
executing a set of instructions by a controller connected with an implantable electrode lead, the set of instructions comprises the steps of; selecting an electrode on an implanted electrode lead as a cathode and a different contact as an anode; generating a pulsed electrical field from the cathode contact; simultaneously drawing a current from the electric field toward the selected anode to stimulate the targeted area of the brain; alternating the selection of the anode and the cathode for each next pulse; and adjusting the electric field between the selected cathode contact and the selected anode contact. - View Dependent Claims (18, 19, 20, 21, 22)
