Abstract:
1. A medical device for delivering a pulse waveform to a target site of a patient, comprising: an energy storage device storing electrical energy; a plurality of electrodes electrically coupled to the energy storage device; a plurality of switching elements coupled to the plurality of electrodes; and control circuitry, coupled to the plurality of switching elements, selectively switching the plurality of switching elements between a first state and a second state to direct discharge of the stored energy to be simultaneously output at selected electrodes of the plurality of electrodes to generate discrete sequential resultant output pulses across multiple pathways, the discrete sequential resultant output pulses generating a multi-directional waveform at the target site, wherein the multi-directional waveform generates a stimulation field that rotates stepwise in one of a clockwise direction and a counter-clockwise direction.
