Method and device for use in endoscopic organ procedures
First Claim
1. A bypass conduit for placement within a hollow body organ, comprising:
- a tubular member which defines a main lumen therethrough,a first expandable gasket at a proximal end of the tubular member;
a second expandable gasket distal to the first self-expanding gasket;
wherein said tubular member is flexible between the first and second expandable gaskets;
wherein the main lumen maintains communication from proximal to distal of the hollow body organ;
wherein at least a portion of an outer surface of the tubular member is adapted to maintain fluid communication therealong; and
wherein tissue is secured between the first and the second gasket by the expansion of the first and second expandable gaskets.

Abstract
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.
