Abstract

A method of treating a sphincter provides a sphincter electropotential mapping device with a mapping electrode. The sphincter electropotential mapping device is introduced into at least a portion of the sphincter. Aberrant myoelectric activity of the sphincter is detected. Energy is delivered from the sphincter electropotential mapping device to treat the aberrant myoelectric activity of the sphincter.

Claims

1. A method of treating a sphincter, comprising:

providing a sphincter electropotential mapping device with a mapping electrode;

introducing the sphincter electropotential mapping device into at least a portion of the sphincter;

detecting an aberrant myoelectric activity of the sphincter; and

delivering energy from the sphincter electropotential mapping device to treat the aberrant myoelectric activity of the sphincter.

2. The method of claim 1, wherein the sphincter electropotential mapping device includes a treatment electrode.

3. The method of claim 2, wherein the detection of the aberrant myoelectric activity of the sphincter is detection of an electrical foci.

4. The method of claim 3, wherein the treatment electrode delivers sufficient energy to treat the foci.

5. The method of claim 2, wherein the detection of the aberrant myoelectric activity of the sphincter is a detection of an electrically conductive pathway.

6. The method of claim 5, wherein the treatment electrode delivers sufficient energy to treat the pathway.

7. The method of claim 1, wherein detection of the aberrant myoelectric activity of the sphincter is a detection of an electrical foci.

8. The method of claim 7, wherein the mapping electrode delivers sufficient energy to treat the foci.

9. The method of claim 1, wherein the detection of the aberrant myoelectric activity of the sphincter is a detection of an electrically conductive pathway.

11. The method of claim 1, wherein the sphincter is a lower esophageal sphincter.

12. A method of treating a stomach, comprising:

providing a stomach electropotential mapping device with a mapping electrode;

introducing the stomach electropotential mapping device into at least a portion of the stomach;

detecting an aberrant myoelectric activity of the stomach; and

delivering energy from the stomach electropotential mapping device to treat the aberrant myoelectric activity of the stomach.

13. The method of claim 12, wherein the stomach electropotential mapping device includes a treatment electrode.

14. The method of claim 13, wherein the detection of the aberrant myoelectric activity of the stomach is detection of an electrical foci.

15. The method of claim 14, wherein the treatment electrode delivers sufficient energy to treat the foci.
