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 portion 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 portion of the main body portion, and a second stimulation arm extending from the distal end portion of the main body portion;
advancing the first stimulation arm through a first intervertebral foramen from inside the epidural space; and
advancing the second stimulation arm through a second intervertebral foramen from inside the epidural space.

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 aim 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.

13. An implantable lead for providing electrical stimulation to a patient, the lead comprising:
-
a lead body having a proximal end portion, a distal end portion, and a longitudinal length, the lead body comprising a main body portion having a proximal end portion, a distal end portion, and a longitudinal length, a first stimulation arm extending from the distal end portion of the main body portion, a plurality of first electrodes disposed along the first stimulation arm, a second stimulation arm extending from the distal end portion of the main body portion, and a plurality of second electrodes disposed along the second stimulation arm, wherein the first stimulation arm is configured and arranged for extending through a first intervertebral foramen when the main body portion is disposed in the epidural space, wherein the second stimulation arm is configured and arranged for extending through a second intervertebral foramen when the main body portion is disposed in an epidural space; a plurality of terminals disposed along the proximal end portion of the main body portion; and a plurality of conductors electrically coupling the plurality of terminals to the plurality of first electrodes and to the plurality of second electrodes. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
