Abstract

An electrostimulation device (e.g., 100) consists of a single paddle (e.g., 102) and at least one lead (e.g., 110) for connecting the electrostimulation device to a pulse generator. The paddle has at least one electrode (e.g., 106) for providing electrical stimulation. The electrode(s) is provided in an area (A) of the paddle and a ratio of the width of the area to the length of the area is greater than 0.5. The present invention also relates to a paddle (e.g., 102) implantable in a vertebra.

Claims

1. An electrostimulation device consisting of:

a single paddle;

at least one lead for connecting to a pulse generator; and

at least one electrode for providing electrical stimulation in an area of the paddle;

wherein the ratio of the width of said area to the length of said area is between 0.75 and 1.25 inclusive.

2. An electrostimulation device as claimed in claim 1, wherein said area has a length of less than 25 mm.

3. An electrostimulation device as claimed in claim 1, wherein said area has a width of greater than 10 mm.

5. An electrostimulation device as claimed in claim 1;

wherein the at least one electrode comprises a plurality of electrodes.

6. An electrostimulation device as claimed in claim 5, wherein the electrodes are arranged in three or more columns.

7. An electrostimulation device as claimed in claim 6, wherein the electrodes are arranged in three or more rows.

8. An electrostimulation device as claimed in claim 5, wherein the electrodes are at least one of oval and circular.

9. An electrostimulation device as claimed in claim 1, wherein said at least one lead extends from the bottom of the paddle.

10. An electrostimulation device as claimed in claim 1, wherein said at least one lead is provided with a connector for connecting to a pulse generator.

11. An electrostimulation device as claimed in claim 1, wherein said at least one lead is connected to a pulse generator.

12. An electrostimulation device as claimed in claim 1, wherein said paddle is implantable in a vertebra to provide electrical stimulation of a cervical spinal cord.

15. An electrostimulation device as claimed in claim 1, wherein the at least one lead is connected to said paddle.

16. An electrostimulation device as claimed in claim 1, wherein an angle of greater than 180°

is defined between said at least one lead and a front face of the paddle.

17. An electrostimulation device as claimed in claim 16, wherein an angle of approximately 270°

is defined between said at least one lead and the front face of the paddle.

4. An electrostimulation device consisting of:

a single paddle;

at least one lead for connecting to a pulse generator; and

at least one electrode being provided on said paddle for providing electrical stimulation;

wherein the paddle has a length of less than 25 mm.

13-14. -14. (canceled)

18-19. -19. (canceled)

20. A paddle implantable in a vertebra, the paddle comprising:

at least one electrode for providing electrical stimulation;

wherein the length of the paddle is less than or equal to the height of the vertebra.

21. A paddle as claimed in claim 20, wherein said at least one electrode is suitable for providing electrical stimulation of a cervical spinal cord.

24. A paddle as claimed in claim 20, wherein the at least one electrode comprises a plurality of electrodes and wherein the electrodes are arranged in at least three rows and at least three Columns.

22. A paddle for providing electrical stimulation, the paddle comprising:

a plurality of electrodes;

wherein said electrodes are arranged in three or more columns.

23. A paddle as claimed in claim 22, wherein the electrodes are arranged in three or more rows.
