Patent ID: 7937158

Claim:
A stimulator system for generating electrical pulses for application to tissue of a patent, the system comprising: a processor for controlling the system under control of executable instructions; stimulation source circuitry for generating electrical pulses for application to tissue of the patient; and capacitors coupled between the stimulation source circuitry and outputs of the stimulator system; wherein the processor is programmed to control the stimulation source circuitry to provide stimulation according to a multi-stimulation set program that defines multiple pulses to be interleaved according to respective sets of pulse parameters, wherein a multi-stimulation set program defines a program pulse frequency; wherein the processor is further programmed to selectively apply active discharge of capacitors according to the program pulse frequency of a respective multi-stimulation set program by selecting from (i) a first mode of operation that employs an active discharge pulse amplitude that is a first fraction of a preceding stimulation pulse for a program pulse frequency above a first frequency threshold and below a second frequency threshold, and (ii) a second mode of operation that employs an active discharge pulse amplitude that is a second fraction of a preceding stimulation pulse for a program pulse frequency above the second frequency threshold, wherein the second fraction is less than the first fraction.
