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 contacting surface area greater than the first tissue contacting surface area; and
simultaneously sourcing anodic electrical current from the first electrode to a first neural fiber bundle, thereby increasing an action potential threshold of the first neural fiber bundle, and sinking cathodic electrical current from a second neural fiber bundle to the second electrode, thereby providing 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.
