摘要：
Provided herein are balloon systems and related methods for the treatment of obesity. The system includes a trans-abdominal gastric cannula and size-varying balloons that, with the assistance of the cannula(s) and anchors, are specially positioned and anchored to the gastric wall. The size-varying balloon may have an annulus that in combination with reliable and precise balloon positioning, minimizes the risk of gastric obstruction during use. A malabsorption sleeve may be positioned in the small intestine to further restrict caloric intake through the small intestine. The specially-configured gastric cannula provides a platform for accessing the gastric environment that facilitates precise handling, manipulation, and placement of balloons, including an annular-shaped balloon, in the gastric environment, including by balloon anchors connecting the balloon wall to the lumen-facing stomach wall.
