Electrode array having concentric split ring electrodes and methods of making the same
First Claim
1. A device for electrical stimulation, comprising:
- a lead body having a longitudinal surface, a circumference, and a distal end;
at least one ring array disposed on the distal end of the lead body, each of the at least one ring array comprising at least three split ring electrodes; and
an insulative material disposed between the at least three split ring electrodes;
wherein each of the at least three split ring electrodes comprises a stimulating portion and a base portion coupled to the stimulating portion and having an end spaced-apart from the stimulating portion, the stimulating portion extending around a portion of the circumference of the lead body and the base portion extending uniformly in a circumferential direction, relative to the circumference of the lead body, away from the stimulating portion to the end of the base portion spaced-apart from the stimulating portion, wherein at least a portion of the base portion of each of the at least three split ring electrodes is disposed radially inward, and separated by a layer of the insulative material, from at least a portion of the stimulating portion of an adjacent one of the at least three split electrodes;
wherein the device is configured and arranged for electrical 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.
