Abstract
An electronic device and method are disclosed for effecting both nerve fiber and body tissue stimulation. Nerve fiber stimulation is primarily effected by application of pulses, and preferably by application of biphasic pulse pairs the pulses of which are spaced from one another in a pattern such that nerve fiber stimulation applied through plural active electrodes enhances pain suppression. Body tissue treatment is primarily effected by application of a net DC charge, and preferably by application of biphasic pulses that includes a greater number of either negative or positive pulses so that a net DC charge results. The DC charge level is maintained at a substantially constant selected value regardless of pulse variations within established broad limits, and the DC charge level is adjustable between operational modes, as needed.
