Abstract: A method and device for delivering a pulse waveform to a target site of a patient that includes an energy storage device storing electrical energy, and a plurality of electrodes electrically coupled to the energy storage device. Control circuitry, coupled to a plurality of switching elements coupled to the plurality of electrodes, selectively switches 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.

Abstract: A method and apparatus for delivering a pulse waveform to a target site of a patient that includes an energy storage device storing electrical energy and control circuitry, coupled to the energy storage device and a plurality of electrodes, generating the pulse waveform from the stored energy and delivering the pulse waveform to the target site via the plurality of electrodes. Each of the electrodes includes a pair of switching elements that are selectively opened and closed by the control circuitry in response to control signals to produce pulse signals at each output terminal. Continuous multi-directional waveforms are formed by generating phase-shifted signals at each electrode.
