Abstract:
1. A method of electrically stimulating neural tissue of a patient, comprising: generating, by an implantable pulse generator, one or more electrical pulses; applying the one or more electrical pulses to neural tissue of a patient using one or more electrodes of one or more stimulation leads; concurrently with the generating, providing a voltage waveform or signal by the implantable pulse generator; and concurrently with the applying, electrically coupling one or more field effect electrodes of the one or more stimulation leads to the voltage waveform or signal to generate a localized electric field within tissue proximate to the one or more electrodes used to apply the one or more electrical pulses to steer the one or more electrical pulses deeper into patient tissue, wherein the one or more field effect electrodes are adapted to prevent conduction of current through the one or more field effect electrodes.
