PAIN MANAGEMENT WITH STIMULATION SUBTHRESHOLD TO PARESTHESIA
First Claim
Patent Images
1. A method of treating pain in a patient comprising:
- positioning a lead having at least one electrode disposed thereon so that at least one of the at least one electrode is in proximity to a dorsal root ganglion; and
providing stimulation energy to the at least one of the at least one electrode so as to stimulate at least a portion of the dorsal root ganglion,wherein together the positioning of the lead step and the providing stimulation energy step affect pain sensations without generating substantial sensations of paresthesia.

Abstract
Devices, systems and methods are provided for treating pain while minimizing or eliminating possible complications and undesired side effects, particularly the sensation of paresthesia. This is achieved by stimulating in proximity to a dorsal root ganglion with stimulation energy in a manner that will affect pain sensations without generating substantial sensations of paresthesia. In some embodiments, such neurostimulation takes advantage of anatomical features and functions particular to the dorsal root ganglion.

17. A method of treating a patient comprising:
-
identifying a dorsal root ganglion associated with a sensation of pain by the patient; and neuromodulating at least one glial cell within the dorsal root ganglion so as to reduce the sensation of pain by the patient. - View Dependent Claims (18, 19, 20)

21. A method of treating a patient comprising:
-
positioning a lead having at least one electrode disposed thereon so that at least one of the at least one electrode is in proximity to a dorsal root ganglion; and providing stimulation energy to the at least one electrode so as to stimulate at least one blood vessel associated with the dorsal root ganglion in a manner that causes the at least one blood vessel to release an agent which neuromodulates a neuron within the dorsal root ganglion. - View Dependent Claims (22)
