Electrode array having concentric split ring electrodes and methods of making the same
First Claim
1. A device for brain stimulation, comprising:
- a lead body having a longitudinal surface and a distal end;
at least one ring array comprising at least three split ring electrodes disposed on the distal end of the lead body, each of the at least three split ring electrodes comprising a stimulating portion and a base portion coupled to the stimulating portion, the stimulating portion extending around a portion of the circumference of the lead body and the base portion extending in a circumferential direction away from the stimulating portion, the base portion and the stimulating potion each comprising a top surface and a bottom surface opposite the top surface, wherein the split ring electrodes of the at least one ring array are arranged about the circumference of the lead body, and wherein at least a portion of the base portion of each of the at least three split ring electrodes is disposed radially below, and insulated from, at least a portion of the stimulating portion of an adjacent one of the at least three split electrodes, wherein the top surface of the stimulating portion comprises at least a section of a circle having a first radius and the top surface of the base portion comprises at least a section of a second circle having a second radius, the first radius being greater than the second radius; and
an insulative material disposed between the at least three split ring electrodes and disposed directly on top of the top surface of the base portion of each of the at least three split ring electrodes and directly underneath the bottom surface of the stimulating portion of each of the at least three split electrodes;
wherein the device is configured and arranged for brain stimulation.

Abstract
A device for brain stimulation includes a lead body having a longitudinal surface and a distal end. The device further includes at least one ring array. The at least one ring array includes a plurality of split ring electrodes disposed on the distal end of the lead body. Each of the plurality of split ring electrodes includes a stimulating portion and a base portion coupled to the stimulating portion. The split ring electrodes of the at least one ring array are arranged about the circumference of the lead body. At least a portion of the base portion of at least one of the plurality of split ring electrodes is disposed below, and insulated from, at least a portion of the stimulating portion of another of the plurality of split electrodes.
