Abstract: Systems for controlling obesity utilize a number of space occupiers positioned in the stomach to reduce the effective volume of the stomach. Such arrangements provides sufficient stomach volume consumption to induce weight loss, but enable use of space occupiers that are proportioned to minimize the threat of obstruction even if they should migrate into the intestine. In general, numerous small volume space occupiers are placed in the stomach such that the total volume equals or exceeds the single volume of prior art single unit space occupiers. However, each individual space occupier is proportioned so that it will pass without obstruction if it moves into the intestine.

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: The present application describes an implant system useable for positioning an implant device such as a device useful for restricting passage of ingested food into the stomach. In one embodiment, the disclosed system includes a plurality of anchors that may be coupled to tissue within the stomach, or to a tissue tunnel formed by plicating stomach wall tissue. The anchor includes a loop. During use, the implant device is inserted through the loop and expanded such that it retains its position within the loop until removed. Instruments for implanting and explanting the implant device are also described.

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.

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.
