Claim 14:
15. A method for treating pain in a patient, comprising:
delivering an electrical waveform to the patient's neural tissue from a waveform generator via at least one electrode comprising at least one contact in electrical communication with the patient's neural tissue,
wherein the electrical waveform is a multi-phase direct current waveform, wherein the multi-phase direct current waveform comprises an anodic phase and a cathodic phase, the anodic phase and the cathodic phase both comprising a first ramp segment, a second ramp segment, and a third ramp segment,
wherein one of the anodic phase or the cathodic phase provides a therapy signal to the neural tissue, and the other of the anodic phase or the cathodic phase reduces or balances a return charge,
wherein the at least one contact comprises a high charge capacity titanium nitride or platinum material that limits formation of irreversible reaction products when the electrical waveform delivers a charge of 10 μC or more to the neural tissue,
wherein the multi-phase direct current waveform has a period of about 15 seconds or more.
