The present invention involves new interventional methods and devices for reconfiguring a portion of the gastrointestinal tract. The procedures are generally performed laparoscopically and may generally be described as laparoscopic plication gastroplasty (LPG) in which, after obtaining abdominal access, spaced apart sites on a gastric wall are engaged, approximated and fastened to create one or more tissue folds forming one or more plications projecting into the gastrointestinal space. The serosal tissue may optionally be treated during the procedure to promote the formation of a strong serosa-to-serosa bond that ensures the long-term stability of the tissue plication. These procedures are preferably carried out entirely extragastrically (i.e. without penetrating through the gastrointestinal wall), thereby minimizing the risks of serious complications.

The present invention involves new interventional methods and devices for reducing gastric volume, and thereby treating obesity. The procedures are generally performed laparoscopically and may generally be described as laparoscopic plication gastroplasty (LPG) in which, after obtaining abdominal access, spaced apart sites on a gastric wall are engaged and approximated to create one or more tissue folds that are then secured by placing one or more tissue fasteners to produce one or more plications projecting into the gastrointestinal space. The serosal tissue may optionally be treated during the procedure to promote the formation of a strong serosa-to-serosa bond that ensures the long-term stability of the tissue plication. These procedures are preferably carried out entirely extragastrically (i.e. without penetrating through the gastrointestinal wall), thereby minimizing the risks of serious complications. Minimally invasive devices for approximating and fastening soft tissues are disclosed that enable these new interventional methods to be carried out safely, efficiently and quickly. Methods for reversing the procedure are also disclosed.

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.
