Abstract
A lead for providing electrical stimulation signals to the spinal cord and method of use thereof. The lead is implanted in the epidural space and includes an elongate lead paddle located at the distal end of the lead. An array of electrodes is located on the lead paddle. The array has at least three columns of electrodes and includes a column having at least one electrode positioned substantially over the midline of the lead paddle, a column of at least one electrode positioned laterally of the midline on one side thereof and a column of at least one electrode positioned laterally of the midline one the other side thereof. At least one of the columns within the array has more than one electrode. Each of the electrodes is interconnected by a conductor to a respective terminal at the proximal end of the lead. The lead is implanted such that the midline of the of the lead paddle is positioned over the midline of the spinal cord. Each electrode is independently selectable such that the spinal cord may be stimulated unilaterally or bilaterally.
