Use of interphase to incrementally adjust the volume of activated tissue
First Claim
1. A neurostimulation system, comprising:
- one or more electrical contacts;
output stimulation circuitry capable of outputting a multiphasic waveform to the one or more electrical contacts; and
control circuitry capable of varying an interphase and an amplitude of the multiphasic stimulation waveform in response to a single actuation of an actuator, wherein the amplitude of the multiphasic waveform is varied from a first non-zero value to a second different non-zero value.

Abstract
A neurostimulation system comprises one or more electrical contacts, output stimulation circuitry capable of outputting a multiphasic waveform (e.g., a biphasic waveform) to the electrical contact(s), and control circuitry capable of varying an interphase of the multiphasic stimulation waveform. The control circuitry may also be capable of varying an amplitude of the multiphasic waveform. In this case, the control circuitry may be capable of discretely varying the amplitude of the multiphasic stimulation energy in a plurality of low-resolution steps, and may further be capable of varying the interphase of the multiphasic stimulation energy between the low-resolution steps; for example, by discretely varying the interphase in a plurality of high-resolution steps between each adjacent pair of low-resolution steps.
