1. An implantable lead for stimulating nerve tissues comprising:
- a plurality of terminals;
a plurality of electrodes;
a plurality of conductors coupled to the terminals and electrodes; and
a paddle shaped body wherein the body comprises;
a flat face side where the electrodes are exposed;
a backside opposite of the flat face side; and
winged tips connected to the backside and the flat face side, wherein the wing tips have curved portions extending from the flat face side such that the curved portions and the flat face side form a concave surface.

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.
