An implantable stimulation system including an epidural lead for spinal cord stimulation that includes a paddle having an array of electrodes coupled to conductors within the lead body. The paddle includes score lines that extend along the length and width of either the front or back facets of the paddle portion. The score lines increase the flexibility of the paddle in both the length and width directions which facilitate the implantation of the paddle within the epidural space of the spinal cord, and further permits the paddle to conform more uniformly to the target area of implantation to minimize the gap between the electrodes and targeted fibers.
