Abstract

A paddle lead includes a paddle body with a plurality of electrodes disposed on the paddle body. The plurality of electrodes includes a first electrode and a second electrode. The first electrode and the second electrode are disposed laterally around the circumference of the paddle body. At least one connecting wire is disposed on, or within, the paddle body to electrically couple the first electrode and the second electrode.

Claims

1. A paddle lead, comprising:

a paddle body having a first major surface, an opposing second major surface, and a transverse circumference;

a plurality of electrodes disposed on the paddle body, the plurality of electrodes comprising

a first electrode and a second electrode disposed laterally from one another along the first major surface of the paddle body, and

a third electrode and a fourth electrode disposed laterally from one another along the second major surface of the paddle body; and

a plurality of connecting wires, wherein a first connecting wire of the plurality of connecting wires electrically couples the first electrode to the second electrode, wherein a second connecting wire of the plurality of connecting wires electrically couples the third electrode to the fourth electrode, and wherein at least one of the first or second connecting wires is a peripheral connecting wire that is disposed on at least one of the first major surface or the second major surface of the paddle body.

2. The paddle lead of claim 1, wherein the plurality of electrodes are disposed in similar orientations on each of the first major surface and the second major surface.

3. The paddle lead of claim 1, wherein at least one of the connecting wires directly connects one of the plurality of electrodes to another of the plurality of electrodes.

4. The paddle lead of claim 1, wherein the paddle body is flexible.

5. The paddle lead of claim 1, wherein the paddle body is fabricated from a non-conductive, biocompatible material suitable for subcutaneous implantation.

6. The paddle lead of claim 1, wherein the first and second electrodes are axially aligned with the third and fourth electrodes along a length of the paddle body.

7. The paddle lead of claim 1, wherein the plurality of electrodes further comprises a fifth electrode disposed laterally from the first electrode and the second electrode along the first major surface of the paddle body.

8. The paddle lead of claim 1, wherein the plurality of electrodes further comprises a sixth electrode disposed laterally from the third electrode and the fourth electrode along the second major surface of the paddle body.

9. The paddle lead of claim 1, wherein the paddle body is formed from a non-conductive material.

10. The paddle lead of claim 1, wherein the plurality of connecting wires comprises a third connecting wire electrically coupling the first electrode of the first major surface to the third electrode of the second major surface.

11. The paddle lead of claim 10, wherein the third connecting wire is a peripheral connecting wire that is disposed on a portion of the first major surface and a portion of the second major surface.

12. A stimulation system, comprising:

the paddle lead of claim 1; and

a control module coupleable to the paddle lead.

13. A paddle lead, comprising:

a lead body for coupling the paddle lead to one or more external devices; and

a paddle body distal to the lead body, the paddle body having a first major surface and an opposing second major surface, the paddle body comprising a plurality of electrodes disposed on the paddle body such that at least two of the plurality of electrodes are laterally disposed from one another on the first major surface of the paddle body and at least two of the plurality of electrodes are laterally disposed from one another on the second major surface of the paddle body, wherein at least some of the laterally-disposed electrodes form at least one lateral loop of electrically coupled electrodes disposed around at least a portion of a transverse circumference of the paddle body, each of the at least one lateral loops comprising

at least two of the laterally-disposed electrodes of the first major surface,

at least two of the laterally-disposed electrodes of the second major surface, and

a plurality of connecting wires, a first connecting wire of the plurality of connecting wires electrically coupling together the at least two laterally-disposed electrodes of the first major surface, a second connecting wire of the plurality of connecting wires electrically coupling together the at least two laterally-disposed electrodes of the second major surface, and at least one of the plurality of connecting wires electrically coupling together one of the at least two laterally-disposed electrodes of the first major surface with one of the at least two laterally-disposed electrodes of the second major surface;

wherein at least one of the first or second connecting wires is a peripheral connecting wire that is disposed on at least one of the first major surface or the second major surface of the paddle body.

14. The paddle lead of claim 13, wherein at least one of the connecting wires is a transverse connecting wire that is disposed within the paddle body.

15. The paddle lead of claim 13, wherein the paddle lead comprises at least two laterally-disposed lateral loops.

16. The paddle lead of claim 13, wherein the paddle body is formed from a non-conductive material.
