Patent ID: 7957814

Claim:
A system comprising: a medical device that includes: one or more electrodes, a stimulation generator configured to deliver electrical stimulation via the electrodes, and a switch device configured to couple the stimulation to selected electrodes; and a programmer device configured to program the medical device, wherein the programmer device is configured to control the medical device to: deliver electrical stimulation to a patient via a first electrode combination, deliver electrical stimulation to the patient via a second electrode combination on a time-interleaved basis with the electrical stimulation delivered via the first electrode combination, incrementally increase an amplitude of the electrical stimulation delivered via the second electrode combination while the electrical stimulation delivered via the second electrode combination is delivered on a time-interleaved basis with the electrical stimulation delivered via the first electrode combination, and incrementally decrease an amplitude of the electrical stimulation delivered via the first electrode combination while the electrical stimulation delivered via the second electrode combination is delivered on a time-interleaved basis with the electrical stimulation delivered via the first electrode combination.
