1. A method of stimulating tissue of a patient, comprising:
- placing an array of electrodes in proximity to the tissue;
conveying electrical current between the electrodes of the array to stimulate a tissue site;
incrementally shifting the electrical current from at least one cathode to at least another cathode over a first range of fractionalized current values; and
incrementally shifting the electrical current from at least one anode to at least another anode over a second range of fractionalized current values;
wherein the first and second ranges of fractionalized current values respectively have differing first and second average step sizes.

Abstract
A method of stimulating tissue of a patient is provided. The method comprises placing an array of electrodes in proximity to the tissue, conveying electrical current between the electrodes of the array to stimulate a tissue site, incrementally shifting the electrical current from at least one cathode to at least another cathode over a first range of fractionalized current values, and incrementally shifting the electrical current from at least one anode to at least another anode over a second range of fractionalized current values. The step sizes for the first and second ranges of fractionalized current values differ.

12. A method of stimulating tissue of a patient, comprising:
-
placing an array of electrodes in contact with the tissue; conveying electrical current between the electrodes of the array to stimulate a tissue site; incrementally shifting the electrical current from at least one cathode to at least another cathode over a first range of fractionalized current values; and incrementally shifting the electrical current from at least one anode to at least another anode over a second range of fractionalized current values; wherein the endpoints of each of the first and second ranges respectively has a 100%/0% fractionalized current value and a 0%/100% fractionalized current value, the first range comprises a first total number of fractionalized current values, and the second range comprises a second total number of fractionalized current values different from the first total number of fractionalized current values. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
