Abstract
Techniques are provided for controlling and delivering spinal cord stimulation (SCS) or other forms of neurostimulation. In one example, neurostimulation pulses are generated wherein successive pulses alternate in polarity so that a pair of electrodes alternate as cathodes. Each pulse has a cathodic amplitude sufficient to achieve cathodic capture of tissues adjacent the particular electrode used as the cathode for the pulse. The neurostimulation pulses are delivered to patient tissues using the electrodes to alternatingly capture tissues adjacent opposing electrodes via cathodic capture to achieve a distributed virtual stimulation cathode. Various pulse energy savings techniques are also set forth that exploit the distributed virtual stimulation cathode.
