Abstract
An implantable stimulation system including epidural lead for spinal cord stimulation that includes a paddle having a curved proximal end and lateral winged tips and an array of electrodes coupled to conductors within a lead body. The conductors couple to a pulse generator or other stimulation device. The curved and winged paddle provides more complete electrical stimulation coverage to targeted human tissue by minimizing the potential gap between electrodes and targeted fibers.
