Stomach lining funnel with anastomosis

An anastomosis device comprises a collapsible frame forming a funnel with a wide opening narrowing to a central lumen; a membrane covering the collapsible frame, the collapsible frame and the membrane providing 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; and 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 first hole in the gastric wall and the second hole in the small intestine, wherein the funnel is configured to substantially close off the pylorus and direct food entering the stomach via a patient's esophagus into the wide opening, through the funnel and into the small intestine via the anastomosis component and wherein the collapsible frame, in the expanded configuration, is configured to cover a fundus and a greater curvature of the stomach and lay flat against the gastric wall such that the collapsible frame and the membrane limit nutrient contact from lined portions of the gastric wall. 18386714_1 (GHMatters) P112783.AU.1 WO 2019/009918 PCT/US2017/041069 10 20 21 20 '-40 25FIG.lBA
