Patent ID: 7979133

Claim:
A system for treating chronic pain in a patient using spinal cord stimulation, wherein (i) the chronic pain includes a first pain component within a first bodily sub-region of the trunk of the patient, (ii) the chronic pain includes a second pain component within a second bodily sub-region of the lower extremities of the patient separated from the first bodily sub-region by intervening bodily sub-regions, the system comprising: a paddle structure adapted to be implanted within the epidural space of the patient with at least 10 electrodes disposed in at least five mutually adjacent columns and at least two adjacent rows on the paddle structure; a pulse generator that is electrically coupled to the paddle structure and that is programmable to deliver pulses to the spinal cord of the patient using the electrodes of the paddle structure 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 to treat chronic pain in the first bodily sub-region, the first set of stimulation parameters applied through the first active electrode, has a restricted spatial resolution to stimulate a first set of one or more dorsal column fibers; and (ii) generate a second electrical field, created by stimulation pulses having a second set of stimulation parameters including one or more second active electrode to treat chronic pain in the second bodily sub-region, the second set of stimulation parameters applied through the second active electrode, has a restricted spatial resolution to stimulate a second set of one or more dorsal column fibers; wherein, in response to the program, the patient experiences paresthesia in the first and second bodily sub-regions and the patient experiences minimal sensory effects from the applied electrical pulses in the intervening bodily sub-regions.
