SYMMETRICAL OUTPUT NEUROSTIMULATION DEVICE

摘要

A method and system of providing therapy to a patient using electrodes implanted adjacent tissue. The method comprises regulating a first voltage at an anode of the electrodes relative to the tissue, regulating a second voltage at a cathode of the electrodes relative to the tissue, and conveying electrical stimulation energy between the anode at the first voltage and the cathode at the second voltage, thereby stimulating the neural tissue. The system comprises a grounding electrode configured for being placed in contact with the tissue, electrical terminals configured for being respectively coupled to the electrodes, a first regulator configured for being electrically coupled between an anode of the electrodes and the grounding electrode, a second regulator configured for being electrically coupled between an anode of the electrodes and the grounding electrode, and control circuitry configured for controlling the regulators to convey electrical stimulation energy between the anode and cathode.

1. A method of providing therapy to a patient using an array of electrodes implanted adjacent neural tissue of the patient, the method comprising:
regulating a first voltage at an anode of the electrodes relative to the neural tissue; regulating a second voltage at a cathode of the electrodes relative to the neural tissue; wherein the first voltage on the anode and the second voltage on the cathode are regulated, such that an average shift in voltage on the anode and cathode relative to the neural tissue is equal to or less than one half a differential voltage between the anode and cathode; and conveying electrical stimulation energy between the anode at the first voltage and the cathode at the second voltage, thereby stimulating the neural tissue.
