Abstract: A method of operating an implantable neuromodulator coupled to an electrode array implanted adjacent tissue of a patient having a medical condition comprises conveying electrical modulation energy to tissue of the patient in accordance with a modulation parameter set, wherein conveying the electrical modulation energy to tissue of the patient in accordance with the modulation parameter set stimulates dorsal horn neuronal elements more than dorsal column neuronal elements.

Abstract: A method of treating a non-neuropathic condition includes implanting an electrical stimulation lead near a dorsolateral funiculus of a patient, the electrical stimulation lead including a plurality of stimulation electrodes; and applying electrical stimulation energy through one or more of the electrodes of the electrical stimulation lead to the dorsolateral funiculus to treat the non-neuropathic condition.

Abstract: A method of stimulating patient nerve tissue includes implanting an electrical stimulation lead in a patient. The electrical stimulation lead includes multiple electrodes disposed thereon and the electrodes are implanted in an epidural space adjacent a spinal cord of the patient. The method further includes coupling the electrical stimulation lead to a control module; implanting the control module in the patient; and generating stimulation current in the control module and delivering the stimulation current to at least one of the electrodes on the electrical stimulation lead. That electrode is an anode and a cathode is provided on the control module. The method also includes electrically stimulating at least one patient nerve tissue using the stimulation current. The stimulated patient nerve tissue is disposed beyond the spinal cord and dorsal and ventral roots extending from the spinal cord.
