The present disclosure involves a method of generating different stimulation waveforms as a part of sacral nerve stimulation therapy. A first stimulation waveform having a first stimulation waveform characteristic is generated. The first stimulation waveform is delivered to a first body part of a patient at least in part via a first channel. A second stimulation waveform having a second stimulation waveform characteristic is generated. The second stimulation waveform characteristic is different from the first stimulation waveform characteristic. The second stimulation waveform is delivered to a second body part of the patient at least in part via a second channel that is separate and independent from the first channel. The first body part and second body part correspond to different organs or different types of nerves.
