Funnel-shaped gastric wall lining with anastomotic site

摘要

The anastomotic apparatus includes a foldable frame that forms a funnel with a wide opening that narrows towards the central lumen, and a membrane that covers the foldable frame. The foldable frame and membrane provide a foldable configuration suitable for intracavitary delivery to the patient's stomach and an extended configuration suitable for lining the inner surface of the gastric wall of the stomach. The anastomotic device is further configured to extend from the central lumen of the foldable frame and penetrate the first hole of the gastric wall and the second hole of the patient's small intestine to form a closed connection between the gastric wall and the small intestine. Includes anastomotic components. The funnel is configured to substantially close the pylorus, directing food entering the stomach into a wide opening, passing through the funnel and into the small intestine through the anastomotic component.
