Current Steering for an Implantable Stimulator Device Involving Fractionalized Stimulation Pulses
First Claim
1. A method for configuring a stimulation pulse in an implantable stimulator device (ISD), comprising:
- determining in the ISD a first pulse to be applied to an electrode for patient therapy;
reconstructing in the ISD the first pulse into a fractionalized pulse, wherein the fractionalized pulse comprises a plurality of second pulses; and
applying the fractionalized pulse to the electrode.

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.

14. A method for configuring stimulation pulses in an implantable stimulator device (ISD), comprising:
-
determining in the ISD a sequence of first pulses to be applied to an electrode for patient therapy, the first pulses in the sequence occurring at a first frequency; reconstructing in the ISD the first pulses into fractionalized pulses to form a sequence of fractionalized pulses, wherein each fractionalized pulse comprises a plurality of second pulses, the plurality of second pulses occurring at a second frequency, wherein the second frequency is greater than the first frequency; and applying the sequence of fractionalized pulses to the electrode. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
