Claim Text:
1. A system for treating pain in a patient, comprising: (1) an electrode assembly configured for intradural implantation, which includes: (2) circuitry configured for electrical coupling with the electrodes to deliver electrical through the electrodes to a targeted subregion of the spinal cord; wherein the electrode assembly is configured to conform to the pial surface of the spinal cord of the patient, and has a sufficiently thin profile such that when the array of electrodes is placed against the pial surface, the CSF filled space is maintained, thereby separating the dura from the spinal cord, preventing mechanical constriction and obstruction of CSF flow between the electrode assembly and the dura; and wherein the electrodes are arrayed on the backing so as to provide a sufficiently concentrated stimulus field such that electrical stimuli can be administered to the whole treatment zone from inside the dura without exciting dorsal nerve rootlets.
