Abstract

The present disclosure relates to a percutaneous paddle stimulation lead that can be steered during implantation. The percutaneous paddle stimulation lead that can be steered in a thickness plane of percutaneous paddle stimulation lead during implantation.

Claims

1. A percutaneous paddle stimulation lead comprising:

a lead body defining a paddle structure, the lead body having two opposing major surfaces, the lead body extending between a proximal end and a distal end;

a plurality of electrical contacts disposed on the lead body; and

a lumen extending through a length of the lead body from the proximal end to the distal end, the lumen configured receive a guide wire and allow the lead body to move along the guide wire.

2. A percutaneous paddle stimulation lead according to claim 1, further comprising a guide wire disposed within the lumen and extending beyond the proximal end to the distal end of the lead body.

3. A percutaneous paddle stimulation lead according to claim 1, wherein the lead body has a width:

thickness aspect ratio of at least 2;

1.

4. A percutaneous paddle stimulation lead according to claim 1, wherein the lead body comprises a plurality of fins disposed along the length of the lead body, the fins are configured to allow the lead body to steer in a lateral direction or within a thickness plane defined between the two opposing major surfaces of the paddle structure.

5. A percutaneous paddle stimulation lead according to claim 4, further comprising a polymeric material disposed about the fins and defining the two opposing major surfaces of the paddle structure.

6. A percutaneous paddle stimulation lead according to claim 4, further comprising a polymeric sheath disposed about the fins and defining the two opposing major surfaces of the paddle structure.

7. A percutaneous paddle stimulation lead according to claim 1, wherein the lead body is configured to allow the lead body to steer within a thickness plane defined between the two opposing major surfaces of the paddle structure.

8. A percutaneous paddle stimulation lead according to claim 1, wherein the lead body comprises a second lumen that terminates within the lead body and is configured to receive a stylet.

9. A percutaneous paddle stimulation lead according to claim 1, wherein the lead body comprises a plurality of stacked segments and a polymeric sheath is disposed about the stacked segments and defining the two opposing major surfaces of the paddle structure.

10. A percutaneous paddle stimulation lead according to claim 9, wherein the stacked segments are not fixed to one another.

11. A percutaneous paddle stimulation lead according to claim 9, further comprising a first steering cable and a second steering cable extending parallel with the lumen, wherein the first steering cable can deflect the lead body in a first direction and the second steering cable can deflect the lead body in a second direction opposing the first direction.

12. A percutaneous paddle stimulation lead according to claim 11, wherein the first steering cable and the second steering cable extend through the plurality of stacked segments.

13. A method of steering a percutaneous paddle stimulation lead comprising;

placing a guidewire into a body, the guidewire extending between a distal end and a proximal end, the distal end being placed in a target area of the body;

sliding a percutaneous paddle stimulation lead along the guidewire until at least a portion of the percutaneous paddle stimulation lead is placed in the target area of the body; and

removing the guidewire from the body, and the percutaneous paddle stimulation lead remains in the target area of the body.

14. A method according to claim 13, wherein the sliding step comprises steering the body with the guidewire wherein the body deflects in a lateral direction or within a thickness plane defined between two opposing major surfaces of the percutaneous paddle stimulation lead.

15. A method according to claim 13, wherein the sliding step comprises pushing the percutaneous paddle stimulation lead along the guidewire with a stylet.

16. A method according to claim 15, wherein the stylet is received within a second lumen that terminates within the percutaneous paddle stimulation lead.

17. A percutaneous paddle stimulation lead comprising:

a lead body defining a paddle structure, the lead body having two opposing major surfaces, the lead body extending between a proximal end and a distal end;

a plurality of electrical contacts disposed on the lead body;

a first steering cable and a second steering cable extending between a proximal end and a distal end of the lead body, wherein the first steering cable can deflect the lead body in a first direction and the second steering cable can deflect the lead body in a second direction opposing the first direction; and

a conductor coil assembly extending parallel with the first steering cable and the second steering cable.

18. A percutaneous paddle stimulation lead according to claim 17, wherein the conductor coil is configured to receive a guidewire and allow the lead body to move along the guidewire.

19. A percutaneous paddle stimulation lead according to claim 17, wherein the lead body comprises a plurality of fins disposed along the length of the lead body, the fins are configured to allow the lead body to steer in a lateral direction or within a thickness plane defined between the two opposing major surfaces of the paddle structure.

20. A percutaneous paddle stimulation lead according to claim 19, further comprising a polymeric sheath disposed about the fins and defining the two opposing major surfaces of the paddle structure.

21. A percutaneous paddle stimulation lead according to claim 17, wherein the lead body is configured to allow the lead body to steer within a thickness plane defined between the two opposing major surfaces of the paddle structure.

22. A percutaneous paddle stimulation lead according to claim 17, wherein the lead body comprises a second lumen that terminates within the lead body and is configured to receive a stylet.

23. A percutaneous paddle stimulation lead according to claim 17, wherein the lead body comprises a plurality of stacked segments and a polymeric sheath is disposed about the stacked segments and defining the two opposing major surfaces of the paddle structure.

24. A percutaneous paddle stimulation lead according to claim 23, wherein the stacked segments are not fixed to one another.
