Current steering for an implantable stimulator device involving fractionalized stimulation pulses
First Claim
1. 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 corresponding fractionalized pulses, wherein each fractionalized pulse is comprised of pulse portions; and
applying the at least two fractionalized pulses to corresponding electrodes on the implantable stimulator device during a final duration, wherein the pulse portions of one fractionalized pulse are not simultaneously applied with the pulse portions of another of the fractionalized pulses during the final duration.

Abstract
A method for configuring stimulation pulses in an implantable stimulator device having a plurality of electrodes is disclosed, which method is particularly useful in adjusting the electrodes by current steering during initialization of the device. In one aspect, a set of ideal pulses for patient therapy is determined, in which at least two of the ideal pulses are of the same polarity and are intended to be simultaneous applied to corresponding electrodes on the implantable stimulator device during an initial duration. These pulses are reconstructed into fractionalized pulses, each comprised of pulse portions. The fractionalized pulses are applied to the corresponding electrodes on the device during a final duration, but the pulse portions of the fractionalized pulses are not simultaneously applied during the final duration.
