Spinal cord stimulation paddle lead and method of making the same
First Claim
Patent Images
1. An implantable medical lead for delivering electrical energy to stimulate a patient, comprising:
- a lead body comprising a plurality of helically wound conductive wires embedded in insulative material, the helically wound conductive wires being wound at a wire spacing pitch;
a paddle comprising a metal layer disposed between insulative layers, wherein a plurality of electrically isolated metal traces are patterned in the metal layer, each metal trace comprises a contact and an electrode exposed through one or several insulative layers, and the contacts of the metal traces are disposed together on the paddle and spaced according to the wire spacing pitch; and
each electrode being electrically coupled to a conductive wire of the lead body.

Abstract
In one embodiment, a method of fabricating an implantable stimulation paddle comprises: providing a sheet of conductive material coupled to a first insulative layer; laser removing portions of the conductive material to form a pattern of conductive material, the pattern of conductive material including a plurality of isolated metal traces; providing a second insulative layer over the pattern of conductive material so that the pattern of conductive material is interposed between the first and second insulative layers; and exposing portions of the metal traces to form electrodes on the paddle for delivering electrical stimulation.
