System and method for electrical pulse charge compensation for implantable medical device capacitance loading effects

摘要

A neurostimulation device and system are provided. At least one neurostimulation lead having a plurality of electrodes is configured for being implanted within tissue of a patient. A shunt capacitance is coupled to one of the electrodes. Time-varying electrical current is delivered to at least one of the electrodes, wherein the shunt capacitance would, without compensation, absorb charge from or inject charge into the tissue in response to time-varying changes in the delivered electrical current, thereby causing an uncompensated electrical waveform to be delivered to the tissue adjacent the one electrode, The absorbed or injected charge is at least partially compensated for, thereby causing a compensated electrical waveform to be delivered to the tissue adjacent the one electrode.
