Systems and leads with a radially segmented electrode array and methods of manufacture

A method of making a lead for a stimulation device comprising:

• 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
• reducing an outer diameter of the at least one pre-electrode disposed on the lead body to remove the thin-walled portions of the at least one pre-electrode to form a plurality of segmented electrodes from the thick-walled portions of the at least one pre-electrode.

• 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, wherein the at least two thick-walled portions and the at least-two thin walled portions have a same outer diameter and an inner diameter of the at least two thick-walled portions is smaller than an inner diameter of the at least-two thin 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;
