Apparatus for performing deep brain stimulation with an electric field
First Claim
1. An apparatus for performing deep brain stimulation with an electromagnetic field, the apparatus including an electrode assembly having multiple electrodes and a phased array system for driving the electrodes to generate the electromagnetic field, wherein the phased array system generates a pulsed signal for supply to the multiple electrodes, wherein the timing of the pulsed signal is staggered between different electrodes to steer the electromagnetic field, and wherein the phased array system is controllable such that the apparatus can vary a phase shift between adjacent electrodes from zero up to a predetermined maximum.
