Patent Images
1. A method of implanting a lead, the method comprising:
- providing a lead comprising a lead body having a distal end, a proximal end, and a longitudinal length, a plurality of electrodes disposed along the distal end of the lead body, a plurality of terminals disposed on the proximal end of the lead body, and a plurality of conductors, each conductor electrically coupling at least one of the electrodes to at least one of the terminals;
inserting a guidewire or stylet into the lead; and
implanting the lead into the patient and around at least a portion of a dorsal root ganglion of the patient using the guidewire or stylet to shape the distal end of the lead body into a coil of at least one complete turn around the portion of the dorsal root ganglion.

Abstract
An implantable electrical stimulation lead including a lead body having a distal end, a proximal end, and a longitudinal length, wherein the distal end of the lead body is formed into a hook or coil shape; a plurality of electrodes disposed along the hook or coil at the distal end of the lead body; a plurality of terminals disposed on the proximal end of the lead body; and a plurality of conductors, each conductor electrically coupling at least one of the electrodes to at least one of the terminals. The lead can be used to stimulate, for example, a dorsal root ganglion with the hook-shaped or coil-shaped distal end disposed around a portion of the dorsal root ganglion.
