Abstract:
1. A method for implanting an electrical stimulation lead into a patient, the method comprising: advancing a distal end of a multi-armed lead into an epidural space of the patient, the multi-armed lead comprising a main body portion, a first stimulation arm extending from a distal end of the main body portion, and a second stimulation arm extending from the distal end of the main body portion; guiding the first stimulation arm into and through a first intervertebral foramen from inside the epidural space; positioning the first stimulation arm in proximity to a first dorsal root ganglion that extends through the first intervertebral foramen, the first stimulation arm positioned with a plurality of electrodes disposed along the first stimulation arm in operational proximity to the first dorsal root ganglion; guiding the second stimulation arm into and through a second intervertebral foramen from inside the epidural space; and positioning the second stimulation arm in proximity to a second dorsal root ganglion that extends through the second intervertebral foramen, the second stimulation arm positioned with a plurality of electrodes disposed along the second stimulation arm in operational proximity to the second dorsal root ganglion.
