Electrode array having embedded electrodes and methods of making the same
First Claim
1. An article for use in manufacturing a lead for electrical stimulation, comprising:
- at least one pre-formed electrode frame formed of an insulative material, each of the at least one pre-formed electrode frame defining a plurality of electrode cavities; and
a plurality of segmented electrodes, each segmented electrode having an entire surface, the entire surface comprising two opposing lateral end surfaces and a longitudinal surface extending between the two opposing lateral end surfaces, wherein the plurality of segmented electrodes are disposed within the plurality of electrode cavities of the at least one pre-formed electrode frame so that the insulative material of the at least one pre-formed electrode frame fully covers the entire surface, except one or both of the two opposing lateral end surfaces, of each of the segmented electrodes.

Abstract
A method of manufacturing a device for brain stimulation includes forming a lead body having a distal end section and coupling at least one pre-electrode to the distal end section of the lead body. The pre-electrode defines a divider with a plurality of partitioning arms, and has a plurality of fixing lumens. A portion of the pre-electrode aligned with the portioning arms is removed to divide the pre-electrode into a plurality of segmented electrodes. Each of the plurality of segmented electrodes defines at least one of the plurality of fixing lumens at least partially disposed through the segmented electrode. A material is introduced through the at least one fixing lumen to couple the plurality of segmented electrodes to the lead body.
