SYSTEM AND METHOD FOR INCREASING RELATIVE INTENSITY BETWEEN CATHODES AND ANODES OF NEUROSTIMULATION SYSTEM
First Claim
1. A method of providing therapy to a patient, comprising:
- placing a plurality of electrodes adjacent to tissue of the patient, the electrodes including first and second electrodes, the first electrode having a first tissue contacting surface area and the second electrode having a second tissue contact surface area greater than the first tissue contacting surface area; and
simultaneously sourcing anodic electrical current from one of the first and second electrodes to the tissue and sinking cathodic electrical current from the tissue to another of the first and second electrodes to provide the therapy to the patient.

Abstract
A method and neurostimulation system for providing therapy to a patient is provided. A plurality of electrodes is placed adjacent to tissue of the patient. The electrodes include first and second electrodes, with the first electrode having a first tissue contacting surface area and the second electrode having a second tissue contact surface area greater than the first tissue contacting surface area. Anodic electrical current is simultaneously sourced from one of the first and second electrodes to the tissue and while cathodic electrical current is sunk from the tissue to another of the first and second electrodes to provide the therapy to the patient.
