Method and device for use in endoscopic organ procedures

Methods and devices for use in tissue approximation and fixation are described herein. The present invention provides, in part, methods and devices for acquiring tissue folds in a circumferential configuration within a hollow body organ, e.g., a stomach, positioning the tissue folds for affixing within a fixation zone of the stomach, preferably to create a pouch or partition below the esophagus, and fastening the tissue folds such that a tissue ring, or stomas, forms excluding the pouch from the greater stomach cavity. The present invention further provides for a liner or bypass conduit which is affixed at a proximal end either to the tissue ring or through some other fastening mechanism. The distal end of the conduit is left either unanchored or anchored within the intestinal tract. This bypass conduit also includes a fluid bypass conduit which allows the stomach and a portion of the intestinal tract to communicate.

Hot liner insertion/removal fixture

A fixture (30) adapted to permit the heated exchange of a liner (14) from an operating vertical furnace (10). The fixture is adapted to secure to the base of the liner (14) to both unlock and lower the heated liner, such as a silicon carbide liner, at an controlled rate. The fixture is also adapted to elevate a new liner into the operating vertical furnace at a controlled rate to control the rate of heating of the liner as it is inserted into the operating vertical furnace. The fixture includes an inner ring (34), a low-friction Teflon® ring (36), and an outer ring (38) permitting the rotation of the inner ring within the outer ring. Advantageously, the low friction ring comprises a flanged portion and a vertical portion allowing rotation of the inner ring within the outer ring even when elevated at extreme temperatures exceeding 500° C.
