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.
