Claim 8:
9. A method for treating pain in a patient, comprising:
delivering an electrical waveform comprising a therapy signal to the patient's spinal cord from a waveform generator via at least one electrode comprising at least one contact in electrical communication with the patient's spinal cord,
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 ramp segment and a plateau segment,
wherein one of the anodic phase or the cathodic phase provides the therapy signal to the spinal cord, 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 spinal cord.
