13. A system for forming a gastric reduction pouch in a stomach associated with an esophagus, comprising:
-
a piston member having a distal end, the piston member being arranged to be passed down the esophagus to place the distal end within the stomach; an elongated member arranged on the piston member, the elongated member having a cross-sectional dimension greater than the piston member to form a movable annular support surface, the elongated member further comprising a plurality of fastener deployment channels communicating with the annular support surface; an annular member carried on the piston adjacent the movable annular support surface; a tissue grabber that grabs stomach tissue and disposes the grabbed stomach tissue between the annular member and the movable annular support surface; and a plurality of fasteners deployable through the fastener deployment channels, whereby, with stomach tissue disposed between the annular member and the movable annular support surface to form a fold of stomach tissue about the piston between the annular member and the movable annular support surface, the plurality of fasteners may be deployed through the fastener deployment channels to secure the stomach tissue fold to the annular member about the piston to form the gastric reduction pouch within the stomach. - View Dependent Claims (14, 15, 16)
