Abstract
A multi-lead system includes a first lead and a second lead. The first lead includes a distal end and a first plurality of electrodes disposed along the distal end of the first lead. The first plurality of electrodes are configured and arranged in a first electrode axis. The second lead includes a distal end and a proximal end. A second plurality of electrodes is disposed along the distal end of the second lead. The second plurality of electrodes are configured and arranged in a second electrode axis. The second lead also includes at least one bend between the distal end and the proximal end to allow for linear alignment of the first electrode axis with the second electrode axis to form a combination electrode axis when the first lead and the second lead are implanted.
