Systems and methods for identifying the circumferential positioning of electrodes of leads for electrical stimulation systems

摘要

A lead assembly for an electrical stimulation system includes terminals disposed along a proximal end of a lead body and electrodes disposed along a distal end of the lead body. The electrodes include segmented electrodes. At least one distal marker is disposed along the distal end of the lead body. The distal marker identifies the circumferential position of at least one of the segmented electrodes along the lead body. The distal marker is aligned with at least one of the segmented electrodes along the longitudinal length of the lead body. At least one proximal marker is disposed along the proximal end of the lead body. The proximal marker is aligned with the distal marker along the longitudinal length of the lead body. The distal marker and the proximal marker are discontinuous with one another along the lead body.
