High frequency neuromodulation system for reducing energy requirements

摘要

An electrical neuromodulation system is disclosed. Electrical modulation energy is delivered at a first frequency from the neuromodulation device to a first set of electrodes having a first combined electrode impedance. A second set of electrodes having a second combined electrode impedance less than the first combined electrode impedance is automatically selected. The electrical modulation energy is delivered at a second frequency to the second set of electrodes, wherein the second frequency is greater than the first frequency.
