PADDLE LEADS AND LEAD ARRANGEMENTS FOR DORSAL HORN STIMULATION AND METHODS AND SYSTEMS USING THE LEADS
First Claim
1. A spinal cord stimulation lead, comprising:
- a paddle body configured and arranged to be implanted into the patient to stimulate a portion of the spinal cord of the patient, the paddle body having a distal end, a proximal end, and a longitudinal length extending from the distal end to the proximal end;
at least one lead body having a distal end portion, a proximal end portion, and a longitudinal length, the distal end portion of each of the at least one lead body being coupled to the proximal end of the paddle body;
a plurality of electrodes disposed on the paddle body, wherein the plurality of electrodes form at least two longitudinal columns including a first column and a second column, wherein the first and second columns are spaced apart laterally by at least 7 mm, center-to-center;
a plurality of terminals disposed along the proximal end portion of the at least one lead body; and
a plurality of conductors electrically coupling the plurality of terminals to the plurality of electrodes.

12. A method of spinal cord stimulation, the method comprising
implanting at least one electrical stimulation lead over a spinal cord of a patient so that a first column of electrodes is disposed over a first dorsal horn of the spinal cord and a second column of electrodes is disposed over a second dorsal horn of the spinal cord that is opposite the first dorsal horn; -
coupling the at least one electrical stimulation lead to a control module; and applying a stimulation current generated by the control module to at least one of the first or second dorsal horns using at least one of the electrodes of the first or second columns of electrodes. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
