| 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 first wing tip and the second wing tip curve away from the substantially flat face to form a concave surface between
a distal end of the first wing tip and a distal end of the second wing tip, wherein each electrode of the plurality of electrodes
is electrically coupled to at least one of the plurality of conductors;
wherein the first and second wing tips exhibit a greater degree of curvature than the substantially flat face along the concave
surface.
