Abstract
The invention provides methods and devices for ablation of stomach tissue to treat obesity. For example, the invention may involve ablation of mucosal tissue to inhibit ghrelin production, recognized as a root cause of increased appetite. The invention alternatively may involve ablation of sub-mucosal tissue to alter myoelectric activity and thereby induce gastroparesis. As a further alternative, gastric muscle tissue, vagal nerves within the stomach or the pyloric region may be ablated to alter stomach function and thereby induce gastroparesis.
