Systems and methods for delivering therapy to the dorsal horn of a patient
First Claim
1. A non-transitory machine-readable medium including instructions, which when executed by a machine, cause the machine to deliver an electrical waveform from an implantable neuromodulator to at least some electrodes in an electrode array in accordance with a modulation parameter set to generate an electric field to stimulate dorsal horn neuronal elements more than dorsal column neuronal elements, wherein:
- a first component of the electrical field generated using the electrical waveform extends along a spinal cord of the patient and a second component of the electrical field generated using the electrical waveform extends transverse to the spinal cord of the patient; and
a gradient across the first component of the electrical field renders the dorsal column neuronal elements less excitable than the dorsal horn neuronal elements are rendered by a gradient across the second component of the electrical field.

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.
