Systems and methods for providing electrical stimulation of multiple dorsal root ganglia with a single lead
First Claim
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.

Abstract
A method for implanting an electrical stimulation lead into a patient includes advancing a distal end of a multi-armed lead into an epidural space of the patient. The multi-armed lead includes first and second stimulation arms extending from a main body portion. The first stimulation arm is guided into and through a first intervertebral foramen. The first stimulation arm is positioned in proximity to a first dorsal root ganglion. The first stimulation arm is positioned with electrodes disposed along the first stimulation arm in operational proximity to the first dorsal root ganglion. The second stimulation arm is guided into and through a second intervertebral foramen. The second stimulation arm is positioned in proximity to a second dorsal root ganglion. The second stimulation arm is positioned with electrodes disposed along the second stimulation arm in operational proximity to the second dorsal root ganglion.
