Abstract

A device for brain stimulation includes a lead having a longitudinal surface, a proximal end and a distal end. A plurality of electrodes are disposed along the longitudinal surface of the lead near the distal end of the lead. At least one marker is disposed on the longitudinal surface of the lead. The at least one marker is configured and arranged to identify a relative position of the plurality of electrodes.

Claims

1. A device for brain stimulation, comprising:

a lead having a longitudinal surface, a proximal end and a distal end;

a plurality of electrodes disposed along the longitudinal surface of the lead near the distal end of the lead; and

at least two marking stripes disposed on the longitudinal surface of the lead, the at least two marking stripes being configured and arranged to identify a relative position of the plurality of electrodes.

2. The device of claim 1, wherein the at least two marking stripes are not antipodal.

3. The device of claim 1, wherein the at least two marking stripes are different in at least one of color, width, or texture.

4. The device of claim 1, wherein the at least two marking stripes are different in color.

5. The device of claim 1, wherein the at least two marking stripes comprises a radioopaque material.

14. An implantable stimulation device, comprising:

the device of claim 1, and

a control module coupleable to the lead.

15. The implantable stimulation device of claim 14, wherein the implantable stimulation device is a deep brain stimulator.

16. A method for brain stimulation, the method comprising:

inserting the device of claim 1 into a cranium of a patient; and

aligning the lead to a selected position using the at least two marking stripes.

6. A device for brain stimulation, comprising:

a lead having a longitudinal surface, a proximal end and a distal end;

a plurality of electrodes disposed along the longitudinal surface of the lead near the distal end of the lead; and

at least one colored cable disposed longitudinally within the lead, the at least one colored cable being configured and arranged to identify a relative position of the plurality of electrodes. a colored cable.

7. The device of claim 6, wherein the at least one colored cable comprises two colored cables, each colored cable having a different color.

8. The device of claim 6, wherein the at least one colored cable comprises a conductor, insulation disposed around the conductor, and a colorant disposed in the insulation.

9. The device of claim 8, wherein the colorant comprises a radioopaque material.

17. A method for brain stimulation, the method comprising:

inserting the device of claim 6 into a cranium of a patient; and

aligning the lead to a selected position using the at least one colored cable.

10. A device for brain stimulation, comprising:

a lead having a longitudinal surface, a proximal end and a distal end, the lead defining a lumen extending longitudinally along the lead, the lumen having a non-circular cross-section;

a plurality of electrodes disposed along the longitudinal surface of the lead near the distal end of the lead;

a longitudinally keyed feature along the proximal end of the lead; and

an aligning member insertable into the lumen of the lead, the aligning member comprising a keyed feature that engages the keyed feature along the proximal end of the lead, wherein the aligning member has a non-circular cross-section corresponding to the non-circular cross-section of the lumen.

11. The device of claim 10, wherein the aligning member comprises a stereotactic frame insert that is insertable into the lumen of the lead.

12. The device of claim 10, wherein the aligning member comprises a stylet insertable into the lumen of the lead.

13. The device of claim 10, wherein the aligning member comprises a lead stop.

18. A method for brain stimulation, the method comprising:

inserting the device of claim 10 into a cranium of a patient; and

aligning the lead to a selected position using the aligning member.

19. The method of claim 18, wherein the aligning member is a stylet.

20. The method of claim 19, further comprising rotating the lead using the stylet.
