1. A method of making a lead for a stimulation device comprising:
- coupling a plurality of electrodes to a plate;
joining individual conductors to each of the plurality of electrodes;
after joining the conductors to the electrodes, placing a mandrel along the midline of the plate;
forming the plate around the mandrel and into a cylinder with the conductors extending through a hollow central lumen of the cylinder;
filling the hollow central lumen of the cylinder with an insulative material to create a lead assembly; and
removing the plate to expose the plurality of electrodes.

Abstract
A method of making a lead for a stimulation device includes forming at least one pre-electrode in the shape of a ring, the at least one pre-electrode comprises at least two thin-walled portions separated by at least two thick-walled portions; disposing the at least one pre-electrode near a distal end of a lead body; joining at least one conductor to each thick-walled portion of the at least one pre-electrode; and grinding the lead body and the at least one pre-electrode to remove the thin-walled portions of the at least one pre-electrode to form segmented electrodes from the thick-walled portions of the at least one pre-electrode.
