Patent ID: 7326207

Claim:
A method of treating obesity comprising: providing a treatment device comprising a catheter having a distal end region, a first treatment region on the distal end region sized and configured for deployment in a duodenum, a second treatment region on the distal end region proximal to the first treatment region, the second treatment region being sized and configured for deployment in a stomach, and a spacing region separating the first treatment region from the second treatment region by a distance sized and configured to permit simultaneous deployment of the first treatment region in the duodenum and deployment of the second treatment region in the stomach, the first and second treatment regions each including at least one electrode, introducing the treatment device into a body region such that the first treatment region is deployed in the duodenum and the second treatment region is at the same time deployed in the stomach, coupling the at least one electrode on each of the first and second treatment regions to a source of energy, and delivering energy from the source to the electrodes on the first and second treatment regions to ablate tissue in the stomach and the duodenum.
