Abstract
A needle assembly for introduction of a paddle style lead near a spinal column of a patient includes a body having a proximal end and a distal end, a lumen with a continuous oblong cross section, and a paddle style lead adapted to accept a stiffening member. The distal end of the body has an introducer portion where the top side of the introducer has an orifice to allow for protrusion of the paddle style lead from the lumen into the spinal column area. The needle has a hub affixed to the proximal end of the body which is adapted to receive a stylet. The needle may also have a stylet that is inserted within the lumen. The introducer of the needle has a curvature extending from the bottom side toward the top side at the distal end and guides the introduction of the paddle style lead near the spinal column.
