CURRENT STEERING FOR AN IMPLANTABLE STIMULATOR DEVICE INVOLVING FRACTIONALIZED STIMULATION PULSES

The present invention relates to an implantable stimulator device, the device being adapted to adjust electrodes thereof by receiving a command to move an amount of current from a first initial pulse of an initial duration on a first electrode to a second initial pulse on a second electrode; reconstructing the first and second pulses into corresponding first and second fractionalized pulses, wherein each fractionalized pulse is comprised of pulse portions; and respectively applying the first and second fractionalized pulses to the first and second electrodes on the implantable stimulator device during a final duration, wherein the pulse portions of first fractionalized pulse are not simultaneously applied with the pulse portions of the second fractionalized pulses during the final duration.
