Abstract

The present invention provides a method of affecting physiological disorders by stimulating a specific location along the sympathetic nerve chain. Preferably, the present invention provides a method of affecting a variety of physiological disorders or pathological conditions by placing an electrode adjacent to or in communication with at least one ganglion along the sympathetic nerve chain and stimulating the at least one ganglion until the physiological disorder or pathological condition has been affected.

Claims

1. A method of treating a pulmonary disorder in a human patient comprising:

placing an electrode on at least one ganglion along the sympathetic nerve chain of the human patient, the at least one ganglion selected from the group consisting of a superior cervical ganglion, a middle cervical ganglion, a T2 ganglion, a T3 ganglion, a T4 ganglion, and a T5 ganglion;

applying an electric signal to the electrode; and

adjusting at least one parameter of the electric signal until the pulmonary disorder has been treated.

2. The method of claim 1, wherein the at least one ganglion is selected from the group consisting of a T-1 through T-4 ganglion, a cervical ganglion, and combinations thereof.

3. The method of claim 1, wherein the electric signal is applied continuously.

4. The method of claim 1, wherein the electric signal is applied intermittently.

5. The method of claim 1, wherein the pulmonary disorder is a disorder of the trachea.

6. The method of claim 1, wherein the pulmonary disorder is a disorder of the bronchus.

7. The method of claim 1, wherein the pulmonary disorder is a disorder of the bronchioles.

8. The method of claim 1, wherein the pulmonary disorder is a disorder of the alveoli.

9. The method of claim 1, wherein the pulmonary disorder is a disorder of the lungs.

10. The method of claim 1, wherein the pulmonary disorder is a disorder of the capillaries of the pulmonary system.

11. The method of claim 1, wherein the pulmonary disorder is a reactive airway disease.

12. The method of claim 1, wherein the pulmonary disorder is a bronchospasm or chronic spasm of the airways.

13. The method of claim 1, wherein the pulmonary disorder is asthma.

14. The method of claim 1, wherein the pulmonary disorder is emphysema.

15. The method of claim 1, wherein the pulmonary disorder is chronic obstructive pulmonary disease.

16. The method of claim 1, wherein the pulmonary disorder is a disorder is silicosis.

17. The method of claim 1, further comprising administering an amount of a pharmaceutical agent to the at least one ganglion.

18. The method of claim 17, wherein the amount is determined based upon the effectiveness of the electrical stimulation of the at least one ganglion.

19. The method of claim 1, further comprising sensing a signal related to the pulmonary disorder.

20. The method of claim 19, wherein the signal is an electric signal.

21. The method of claim 19, further comprising regulating the electrical stimulation in response to said signal.

22. The method of claim 1, wherein the at least one ganglion is the superior cervical ganglion.

23. The method of claim 1, wherein the at least one ganglion is the middle cervical ganglion.

24. The method of claim 1, wherein the at least one ganglion is the T-2ganglion.

25. The method of claim 1, wherein the at least one ganglion is the T-3ganglion.

26. The method of claim 1, wherein the at least one ganglion is the T-4ganglion.

27. The method of claim 1, wherein the at least one ganglion is the T-5ganglion.
