Embodiment Construction

[0031]The stomach is responsible for handling and processing food for healthy and efficient digestion downstream. The proximal stomach serves to accommodate food initially and subsequently transfers it to the distal stomach where the food is ground down by the milling action of the antropyloric unit. The food is broken down into small, easily digestible particles that are allowed to enter the duodenum in a regulated manner. Excessive tension in either the proximal and / or distal stomach may induce dyspeptic symptoms as well as contribute to satiety. As such, increasing gastric wall tension and / or gastric wall stiffening to a critical level prior to or during ingestion of a meal may limit the intake of food due to the induced satiety from the tension. The level of tension needed to induce satiety may vary from subject to subject due to the wall tension being a function of both pressure and compliance.

Abstract

Methods and devices for treating obesity. Pressure is applied to gastric walls in at least one segment of a stomach such that the pressure distends the gastric walls and induces satiety. A hollow capsule can be used to distend the gastric walls. Alternatively, a doughnut-shaped ring may be inflated to an amount sufficient to create intragastric tension and induce satiety. A c-ring including at least one balloon may be placed at a segment of the stomach, where the balloon inflates to a size that creates tension at the segment. A biocompatible material can be injected into the fundus and antrum of the stomach to stiffen the gastric wall to create a fullness feeling.

Description

[0001]This application claims priority to, and incorporates by reference, U.S. Provisional Patent Application Ser. No. 60 / 679,769, which was filed May 11, 2005 and which is entitled, “Methods and Devices for Treating Obesity.”BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to treating obesity. More particularly, the present invention provides techniques for stiffening the gastric walls and / or providing tension to the gastric wall to induce satiety, thereby treating obesity.[0004]2. Description of Related Art[0005]Obesity has become a global epidemic in recent years. In a National Health and Nutrition Examination Survey for 1999-2002 conducted by the Center for Disease Control and Prevention, it is estimated that approximately 30 percent of U.S. adults, or about 60 million people, ages 20 or higher, are obese, i.e., having a body mass index of 30 or higher. Approximately 65 percent of U.S. adults, ages 20 or higher, are overweig...
