ELECTRODE ARRAY HAVING EMBEDDED ELECTRODES AND METHODS OF MAKING THE SAME

摘要

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-eiectrode to the distal end section of the iead 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 piuraiity 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 piurai ity of segmented electrodes to the lead body.
