Abstract: Described herein is a positioning tool having an elongate portion for carrying a medical implant. Also described is a method of positioning a medical implant using an elongate positioning tool. One form of the method includes positioning a medical implant on a distal portion of an elongate positioning tool, inserting the positioning tool with the implant thereon into a body cavity manipulating the positioning tool to position the implant into contact with tissue at an attachment location, attaching the implant to surrounding tissue at the attachment location, separating the implant from the positioning tool, and withdrawing the positioning tool from the body. In a preferred embodiment, the position of the implant is visually confirmed using an endoscope before the implant is attached to surrounding tissue. In one embodiment, the implant is a satiation device and the body cavity is the esophagus and/or stomach. In an alternative embodiment, an expansion structure on the distal end of the elongate portion expands and/or contracts the medical implant to facilitate positioning.

Abstract: A satiation device is described which includes a sheath or liner extending from the proximal or middle stomach to the distal antrum. Food ingested by the patient passes through the sheath or liner, thereby minimizing contact between the ingested food and the stomach. It is believed that over time, reduced contact between food and the stomach will result in decreased Ghrelin production by the patient and a consequent decrease in appetite. In some embodiments, the satiation device may also include a proximal pouch and/or a distal bypass tube.

Abstract: A method for controlling appetite by means of a satiation device is disclosed. The device, which includes a flexible webbing defining proximal and distal openings and a biasing structure, is attached to the patient's stomach with the proximal opening positioned adjacent and below the patient's gastro-esophageal junction. The biasing structure imparts pressure against the wall of the patient's stomach adjacent the gastro-esophageal junction.

Abstract: An intestinal implant includes a proximal anchor self-expandable from a radially compressed position to a radially expandable position for engagement with a wall of the intestinal lumen and a flexible sleeve coupled to the anchor. The sleeve is implanted with the anchor downstream from the pylorus and the sleeve extending further downstream through the intestinal lumen.

Abstract: Various methods and devices are described for retaining a medical implant within a body cavity. According to one aspect, at least a portion of a medical implant is positioned within a body cavity, and a wall of the body cavity is re-shaped such that the re-shaped wall prevents migration of the medical implant out of the body cavity. The re-shaped body wall may form a tissue pocket, tunnel, or other barrier against migration of the implant.
