Abstract: A method of deploying an intraluminal device to the cardiac region of the stomach and an intraluminal system used to deploy an intraluminal device to the cardiac region of the stomach, wherein the intraluminal device has a wall defining a surface and an open portion of the surface that is adapted to be aligned with the gastroesophageal (GE) junction. The surface and the cardiac portion of the stomach are conformable with each other. The method includes deploying the intraluminal device trans-orally to the stomach with an endoscopic deployment device and retaining the device against the cardiac region of the stomach with the open portion generally aligned with the GE junction. The intraluminal device is fastened to the stomach from the abdominal cavity with at least one laparoscopic instrument while concurrently visualizing the device with an endoscope in the stomach while it is being fastened.

Abstract: A bariatric device includes an esophageal member having an esophageal surface that is configured to generally conform to the shape and size of a portion of the esophagus and an anchoring technique anchoring the esophageal member to the portion of the esophagus. The bariatric device includes a cardiac member having a cardiac surface that is configured to generally conform to the shape and size of a portion of the cardiac portion of the stomach and a connector connected with the esophageal member and the cardiac member to cause strain to be applied by the cardiac member to the cardiac portion of the stomach.
