1. An implantable lead for stimulating nerve tissue, comprising:
- a lead body of an insulative material;
a plurality of conductors within the lead body;
a paddle body including;
(i) a plurality of electrodes disposed on a substantially flat face of the paddle body;
(ii) a backside surface; and
(iii) a first wing tip disposed on a first lateral side of the paddle body extending away from the substantially flat face; and
(iv) a second wing tip disposed on a second lateral side of the paddle body extending away from the substantially flat face, wherein the substantially flat face, the first wing tip, and the second wing tip form a convex surface, wherein each electrode of the plurality of electrodes is electrically coupled to at least one of the plurality of conductors.

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.
