Stimulation lead for steering current for stimulation of patient tissue, method of stimulating patient tissue, and implantable medical system

摘要

In one embodiment, a method of electrically stimulating neural tissue of a patient, comprises: 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.
