Stomach lining funnel with anastomosis

An anastomosis device includes a collapsible frame forming a funnel with a wide opening narrowing to a central lumen and a membrane covering the collapsible frame. The collapsible frame and the membrane provide a collapsed configuration suitable for endoluminal delivery to a stomach of a patient, and an expanded configuration suitable for lining an internal surface of a gastric wall of the stomach. The anastomosis device further includes an anastomosis component extending from the central lumen of the collapsible frame and being configured to pass through a first hole in the gastric wall and a second hole in a small intestine of the patient and form a sealed connection between the gastric wall and the small intestine. The funnel is configured to substantially close off a pylorus and direct food entering the stomach into the wide opening, through the funnel and into the small intestine via the anastomosis component. 20598950_1 (GHMatters) P112783.AU.2
