Abstract

The invention relates to a method of treating sexual dysfunction. The method includes stimulating sacral nerve roots, S2 and/or S3, with electromagnetic stimulation in or about the sacrum. The stimulation may be achieved with leads terminating in electrodes that extend with an emerging sacral nerve root or extend transverse the sacrum at or about the location of the nerve root to be stimulated. Alternately, spiraled electrodes and nerve cuffs may be used to stimulate the nerve root within the sacrum, as it emerges from the sacrum, or outside the sacrum. In this manner, the selected sacral nerve root may be stimulated to provide genital stimulation and thereby induce orgasm.

Claims

1. A method for treating sexual dysfunction, the method comprising:

generating a stimulation pulse; and

stimulating a sacral nerve root with the stimulation pulse and with at least one electrode to achieve genital stimulation, the at least one electrode located about the sacrum.

2. The method of claim 1, wherein the genital stimulation induces orgasm.

3. The method of claim 1, wherein the sacral nerve root is selected from a group consisting of S1, S2, S3, S4, and S5.

4. The method of claim 1, wherein the at least one electrode is placed in the foramen extending from the sacrum.

5. The method of claim 1, wherein the at least one electrode is placed in the epidural space.

6. The method of claim 1, wherein the at least one electrode comprises a electrode cuff.

7. The method of claim 1, wherein the at least one electrode comprises a lead spiral placed about the sacral nerve root.

8. The method of claim 1, wherein the at least one electrode comprises at least one lead terminating in electrodes.

9. The method of claim 1, the method further comprising:

placing the at least one electrode about the sacrum.

10. The method of claim 1, the method further comprising:

adjusting at least one parameter associated with a stimulation pattern, the stimulation pattern used for stimulating the sacral nerve root.

11. The method of claim 10, wherein the at least one parameter is a pulse frequency.

12. The method of claim 10, wherein the at least one parameter is associated with a polarity of the at least one electrode.

13. The method of claim 10, wherein the at least one parameter is associated with an amplitude of a stimulation pulse.

14. The method of claim 1, the method further comprising:

implanting a stimulation pulse generator which provides a pattern of stimulation pulses upon activation.

15. The method of claim 14, the method further comprising:

activating the stimulation pulse generator with an activation device.

16. The method of claim 15, wherein the activation device comprises a magnet.

17. The method of claim 15, wherein the activation device comprises a radio frequency generator.

18. A system for treating sexual dysfunction, the system comprising:

at least one electrode located about a sacral nerve root of a body, the at least one electrode located about a sacrum of the body;

an implantable stimulation pulse generator coupled to the at least one electrode and located internal to the body, the implantable stimulation pulse generator generating, upon activation, a stimulation pulse pattern in the at least one electrode effective for genital stimulation; and

an activation device located external to the body, the activation device operable to activate the implantable stimulation pulse generator.

19. The system of claim 18, wherein the activation device comprises a magnet.

20. The system of claim 18, wherein the activation device comprises a radio frequency signal generator.

21. The system of claim 18, wherein the genital stimulation induces orgasm.

22. A method for treating sexual dysfunction, the method comprising:

placing at least one electrode proximate to an S3 sacral nerve root about the sacrum;

stimulating the S3 sacral nerve root with the at least one electrode in an effective amount to achieve genital stimulation wherein the genital stimulation induces orgasm.
