Abstract

The invention relates to methods of applying energy to various body portions to produce a therapeutic response. According to embodiments, the applied energy is ultrasound and may be delivered by an ultrasound focusing device deployed in the body, for example, by using an endoscope. The energy may be used to effect a variety of therapeutic responses, including ablating lesions in the gall bladder, treating gastrointestinal reflux disease, or treating fecal incontinence.

Claims

1. A method of treating a patient with gastrointestinal reflux disease comprising:

applying energy from a device to an esophageal sphincter to produce a therapeutic response,

wherein the therapeutic response includes effecting sufficient injury to the esophageal sphincter to cause hyperplasia,

wherein the entire device is positioned outside of an esophagus of the patient during the step of applying energy.

2. The method of claim 1, wherein the applied energy is ultrasound.

3. The method of claim 1, further comprising adjusting the amount of energy applied to the esophageal sphincter.

4. The method of claim 1, wherein the therapeutic response includes bulking tissue of the esophageal sphincter.

5. The method of claim 1, wherein the energy is applied to a portion of the esophageal sphincter below a surface of the esophageal sphincter.

6. The method of claim 1, wherein the device is an ultrasound device, and further comprising focusing the energy from the ultrasound device on a portion of the esophageal sphincter.

7. The method of claim 6, wherein the energy is focused below a surface of the esophageal sphincter.

8. The method of claim 1, wherein the entire device is positioned outside of the patient during the step of applying energy.

9. A method of treating a patient with gastrointestinal reflux disease comprising:

applying energy to an esophageal sphincter to produce a therapeutic response,

wherein the therapeutic response includes effecting sufficient injury to the esophageal sphincter to cause hyperplasia,

wherein the energy is applied to the esophageal sphincter via an ultrasound device, and further comprising focusing the energy from the ultrasound device on a portion of the esophageal sphincter,

wherein the ultrasound device is positioned outside of the patient.

10. A method of treating a patient with gastrointestinal reflux disease comprising:

applying energy from a device to an esophageal sphincter to produce a therapeutic response,

wherein the energy is applied to a portion of the esophageal sphincter below a surface of the esophageal sphincter,

wherein the entire device is positioned outside of an esophagus of the patient during the step of applying energy.

11. The method of claim 10, wherein the applied energy is ultrasound.

12. The method of claim 10, further comprising adjusting the amount of energy applied to the esophageal sphincter.

13. The method of claim 10, wherein the therapeutic response is effecting sufficient injury to the esophageal sphincter to cause hyperplasia.

14. The method of claim 13, wherein the therapeutic response includes bulking tissue of the esophageal sphincter.

15. The method of claim 10, wherein the therapeutic response includes bulking tissue of the esophageal sphincter.

16. The method of claim 10, wherein the device is an ultrasound device, and further comprising focusing the energy from the ultrasound device on a portion of the esophageal sphincter.

17. The method of claim 10, wherein the entire device is positioned outside of the patient during the step of applying energy.

18. A method of treating a patient with gastrointestinal reflux disease comprising:

applying energy to an esophageal sphincter to produce a therapeutic response,

wherein the energy is applied to a portion of the esophageal sphincter below a surface of the esophageal sphincter,

wherein the energy is applied to the esophageal sphincter via an ultrasound device, and further comprising focusing the energy from the ultrasound device on a portion of the esophageal sphincter,

wherein the ultrasound device is positioned outside of the patient.

19. A method of treating a patient with fecal incontinence comprising:

applying energy from a device to an anal sphincter to produce a therapeutic response,

wherein the therapeutic response is effecting sufficient injury to the anal sphincter to cause hyperplasia,

wherein the entire device is positioned outside of an anus of the patient during the step of applying energy.

20. The method of claim 19, wherein the applied energy is ultrasound.

21. The method of claim 19, further comprising adjusting the amount of energy applied to the anal sphincter.

22. The method of claim 19, wherein the therapeutic response includes bulking tissue of the anal sphincter.

23. The method of claim 19, wherein the energy is applied to a portion of the anal sphincter below a surface of the anal sphincter.

24. The method of claim 19, wherein the device is an ultrasound device and further comprising focusing the energy from the ultrasound device on a portion of the anal sphincter.

25. The method of claim 24, wherein the energy is focused below a surface of the anal sphincter.

26. The method of claim 19, wherein the entire device is positioned outside of the patient during the step of applying energy.

27. A method of treating a patient with fecal incontinence comprising:

applying energy to an anal sphincter to produce a therapeutic response,

wherein the energy is applied to the anal sphincter via an ultrasound device,

the method further comprising focusing the energy from the ultrasound device on a portion of the anal sphincter, and

positioning the ultrasound device outside the patient,

wherein the therapeutic response is effecting sufficient injury to the anal sphincter to cause hyperplasia.
