Abstract:
1. An obesity treatment system 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 to separately treat the duodenum and stomach, the first and second treatment regions each including at least one electrode, the first treatment region having a first length and a first width, the first length exceeding the first width, and the second treatment region having a second length and a second width, the second width of the second treatment region exceeding the first width of the first treatment region, a source of tissue ablation energy, a coupling connecting the at least one electrode on each of the first and second treatment regions to the source of energy, and a controller to deliver energy from the source to the electrodes on the first and second treatment regions to ablate tissue in the duodenum and stomach.
