摘要

PROBLEM TO BE SOLVED: To provide a device, system and method of selectively stimulating portions of spinal nerves, particularly one or more dorsal root ganglions (DRGs), to treat chronic pain while minimizing deleterious side effects such as undesired motor responses.SOLUTION: A system for positioning a lead 100 near a spinal nerve comprises: a lead; a sheath having a curved distal end and configured to receive the lead therein; and a stylet configured to be positioned within a stylet lumen of the lead.
