Patent ID: 8615300

Claim:
A system for treating pain in a patient using spinal cord stimulation, wherein (i) the pain includes a first pain component within a first bodily sub-region of a trunk of the patient, (ii) the pain includes a second pain component within a second bodily sub-region of lower extremities of the patient separated from the first bodily sub-region by intervening bodily sub-regions, the system comprising: a lead having proximal and distal ends; a paddle structure adapted to be implanted within epidural space of the patient near the distal end of the lead, the paddle structure having electrodes disposed in at least four mutually adjacent columns and at least two adjacent rows within the paddle structure; a pulse generator configured to be joined to the proximal end of the lead, electrically coupled to the paddle structure and that is programmable to deliver pulses to a spinal cord of the patient using the electrodes of the paddle structure; and a non-transient computer-readable medium with instructions stored thereon that, when executed, cause the pulse generator to: (i) generate a first electrical field, created by stimulation pulses having a first set of stimulation parameters including one or more first active electrode within the paddle structure to treat pain in the first bodily sub-region, the first set of stimulation parameters applied through the first active electrode, has restricted spatial resolution to stimulate a first set of one or more dorsal column fibers; and (ii) generate a second electrical field, created by the stimulation pulses having a second set of stimulation parameters including one or more second active electrode to treat the pain in the second bodily sub-region, the second set of stimulation parameters applied through the second active electrode within the paddle structure, has the restricted spatial resolution to stimulate a second set of one or more dorsal column fibers; wherein, in response to the program, the patient experiences parasthesia in the first and second bodily sub-regions and the patient experiences minimal sensory effects from applied electrical pulses in the intervening bodily sub-regions.
