An instrument for fastening tissue within a body includes an elongated tube having a proximal end for extending outside of the body and a distal end for positioning proximate the tissue; and a distal member configured to fold the tissue together. The distal member includes a first member having a proximal end coupled to the distal end of the tube; and a second member pivotably coupled to the distal end of the first member. The first and second members are configured to install at least one fastener. A grasper is coupled to at least one of the first member and the second member. The second member is pivotable between an open position for receiving tissue and a closed position for folding tissue therebetween. The grasper is configured to project outward from at least one of the first member and the second member when in the open position.

The instrument of claim 8, wherein the elongated tube is flexible to insert in the body transorally and extend through the esophagus and into the stomach. 11. The instrument of claim 8, wherein the grasper is rotatably coupled to the second member. 12. The instrument of claim 8, wherein the first and second members are configured to receive a plurality of fasteners. 13. The instrument of claim 8, wherein one or more flexible wires extend through the elongated tube for manipulating the second member relative to the first member. 14. An instrument for fastening tissue within a body, comprising: an elongated tube having a proximal end and a distal end;a distal member coupled proximate the distal end of the tube and configured to fold a fundus of a stomach toward an esophageal wall, the distal member including a first member and a second member pivotally coupled to the first member, the distal member being configured to install at least one fastener into the folded fundus and esophageal wall, the second member having a connected end and a free end, the second member being configured to pivot between a first position in which the free end is located distally of the connected end and a second position in which the connected end is located distally of the free end; anda grasper configured to grasp at least a portion of the fundus or the esophageal wall; wherein the grasper is coupled to one of the elongated tube and the distal member and configured to move relative to the distal member, and wherein the second member has a first surface facing a second surface of the stationary first member in the second position, the grasper being disposed between the first and second surfaces in the second position. 15. The instrument of claim 14, wherein the grasper includes a first grasping member rotatably coupled to the first member. 16. The instrument of claim 14, wherein the elongated tube is flexible to insert in the body transorally and extend through the esophagus and into the stomach. 17. The instrument of claim 14, wherein the elongated tube includes a lumen to receive an endoscope. 18. The instrument of claim 14, wherein the grasper is configured to project outward from the second member when in the second position. 19. The instrument of claim 14, wherein the first and second members are configured to install multiple fasteners. 20. The instrument of claim 14, wherein one or more flexible wires extend through the elongated tube for manipulating the second member relative to the first member.
