Abstract: Devices and methods for acquiring and fastening tissues folds within an internal organ, such as the stomach, and for applying the methods and devices to producing reductions in organ volume or repair of bariatric procedures, are disclosed. An exemplary method for forming a continuous laterally extending tissue fold involves forming a succession of laterally extending folds having adjacent overlapping fold portions. One exemplary tissue-acquisition device has an open-end roller-and-arm structure that allows individual tissue folds to be formed and fastened, then advanced to an adjacent region within the stomach, for capture of a new fold that will form an extension of the existing fold(s).

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.
