Abstract: In one embodiment, a method of implanting a stimulation lead to stimulate a dorsal root ganglion (DRG) of a patient, comprises: placing a distal portion of the stimulation lead within an implant tool; accessing the epidural space of the patient with the distal end of the implant tool; contacting a surface of a pedicle of the patient with a distal tip of the implant tool above a foramen leading to a target DRG; after contacting the surface of the pedicle with the distal tip, advancing the stimulation lead from a side port of the implant tool, wherein the side port is located proximal to the distal tip of the implant tool; advancing the stimulation lead through the foramen to position one or more electrodes of the stimulation lead adjacent to the target DRG; and providing electrical stimulation to the target DRG to stimulate the target DRG using one or more electrodes of the stimulation lead.
