PAIN MANAGEMENT WITH STIMULATION SUBTHRESHOLD TO PARESTHESIA

摘要

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.

主权项

1. A method of modulating a dorsal root ganglion comprising:
Advancing an electrode along a nerve root sleeve angulation of a dorsal root; Positioning the electrode on or near a dorsal root ganglion associated with the dorsal root; and Providing an electrical current to the electrode so as to neuromodulate the dorsal root ganglion in a manner that causes analgesia without resultant paresthesia, wherein the electrical current has a lower value than that which causes analgesia with resultant paresthesia.
