Abstract

A paddle lead includes a plurality of electrodes configured in at least three rows of three electrodes with the second, intermediate row operable to provide anode guarding. The paddle lead further includes a plurality of grooves disposed on a surface opposite the electrodes to facilitate the insertion of the paddle lead within a patient by inhibiting the veering of the paddle lead to one side or the other of the dorsal column as the paddle lead is advanced along the dorsal column midline during implantation.

Claims

1. A paddle lead, comprising:

a body having a first side and a second side;

at least one electrode disposed on the first side of the body; and

a first groove disposed on the second side of the body, such that when the paddle lead is being implanted in a patient, at least a portion of the first groove engages the patient and facilitates the advancement of the paddle lead towards a targeted implant site in the patient.

2. The paddle lead of claim 1 and further including a second groove disposed on the second side of the body.

3. The paddle lead of claim 2 wherein the first groove and the second groove extend generally parallel to each other.

4. The paddle lead of claim 1 wherein when the paddle lead has been implanted in the patient, at least a portion of the first groove engages the patient and inhibits the movement of the paddle lead with respect to the position of the paddle lead in the patient.

5. The paddle lead of claim 1 wherein the first groove is an arcuate groove.

6. A paddle lead, comprising:

a body having a first side and a second side, first side being generally planar;

the first side of the body includes a plurality of electrodes; and

a plurality of grooves disposed on the second side of the body, such that when the paddle lead is being implanted in a patient, at least a portion of the plurality of grooves engage the patient and facilitate the advancement of the paddle lead towards a target implant site by inhibiting the paddle lead from veering away from the target implant site.

7. The paddle lead of claim 6 wherein each of the plurality of grooves are generally parallel to each other.

8. The paddle lead of claim 7 wherein when the paddle lead has been implanted in the patient, at last a portion of the plurality of grooves engage the patient and inhibit the movement of the paddle lead with respect to the position of the paddle lead in the patient.

9. The paddle lead of claim 8 wherein the plurality of electrodes are arranged in at least a first row, a second row and a third, with each of the first, second and third rows being generally parallel and extending from a first edge of the body to a second edge of the body, and each of the first, second and third rows having at least three contacts, the second row operable to provide anode guarding for at least one of the first and third rows.

10. The paddle lead of claim 9 wherein at least one of the plurality of grooves is an arcuate shaped groove.

11. A paddle lead, comprising:

a body having a first side and a second side and a first edge and a second edge;

the first side of the body including at least a first row of at least three electrodes, a second row of at least three electrodes and a third row of at least three electrodes;

each of the first, second and third row of electrodes being generally parallel and extending from the first edge of the body to the second edge of the body, with the second row being positioned intermediate the first and third rows; and

the second row of electrodes operable to provide anode guarding for at least one of the first and third rows of electrodes.

12. The paddle lead of claim 11 wherein each of the electrodes in the second row are electrically connected together and operate in a common state.

13. The paddle lead of claim 12 where each of the electrodes in the first row are operable in an independent state.

14. The paddle lead of claim 13 and further including a plurality of grooves disposed on the second side of the body, such that when the paddle lead is being implanted in a patient, at least a portion of the plurality of grooves engage the patient and facilitate the advancement of the paddle lead towards a target implant site by inhibiting the paddle lead from veering away from the target implant site.

15. The paddle lead of claim 14, wherein at least one of the plurality of grooves is an arcuate groove.

16. An electrical stimulation system for implantation in a patient, comprising:

a pulse generator for generating electrical pulses;

a paddle lead electrically connectable to the pulse generator, the paddle lead including a body having a first side and a second side and a first edge and a second edge;

the first side of the body including at least a first row of at least three electrodes, a second row of at least three electrodes and a third row of at least three electrodes;

each of the first, second and third row of electrodes being generally parallel and extending from the first edge of the body to the second edge of the body, with the second row being positioned intermediate the first and third rows;

the second row of electrodes operable to provide anode guarding for at least one of the first and third rows of electrodes; and

the second side of the body including a plurality of grooves, such that when the paddle lead is being implanted in the patient, the plurality of grooves engage a portion of the patient and facilitate the advancement of the paddle lead towards a target implant site by inhibiting the paddle lead from veering away from the target implant site.

17. The electrical stimulation system of claim 16 wherein when the paddle lead has been implanted in the patient, at least a portion of the plurality of grooves engage a portion of the patient and inhibit the movement of the paddle lead with respect to the position of the paddle lead in the patient.

18. The electrical stimulation system of claim 17 wherein at least one of the plurality of grooves is arcuate in shape.
