US 2006/0052841 A1 · Multiple channel-electrode mapping

Abstract

In accordance with one aspect of the invention, methods and systems are disclosed for delivering a stimulating signal by a stimulating medical device having a plurality of electrodes. Such methods and systems comprise receiving a signal; filtering the received signal to obtain a plurality of band pass filtered signals; delivering to each electrode of a first group of one or more electrodes, a first set of stimulation signals, wherein the first set of stimulation signals comprises stimulations signals for each of a first group of two or more band pass filtered signals; and delivering to each of electrodes of a second group of one or more electrodes, a second set of stimulation signals, wherein the second set of stimulation signals comprises stimulations signals for each of a second group of one or more band pass filtered signals; and wherein the first set of stimulation signals are delivered at a different effective stimulation rate than the second set of stimulation signals.
