Current steering for an implantable stimulator device involving fractionalized stimulation pulses

A method for configuring stimulation pulses in an implantable stimulator device having a plurality of electrodes, comprising:

• determining a set of pulses for patient therapy, wherein at least two of the pulses are of the same polarity;
• reconstructing each of the at least two pulses into a plurality of sequential pulse portions;
• and
• applying the plurality of sequential pulse portions to corresponding electrodes on the implantable stimulator device during a final duration, wherein the plurality of pulse portions are interleaved during the final duration.

A method for adjusting the electrodes on an implantable stimulator device, comprising:

• 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.
