Abstract
A method for forming an artificial valve includes inserting a sheath having proximal and distal sections and a lumen extending therethrough orally into a body cavity; inserting an endoscope orally into a body cavity, the endoscope being slidably positioned within the sheath; holding tissue in a vicinity of a junction of a stomach and an esophagus where the artificial valve is to be formed, using a holding device extending from the sheath; penetrating through tissue of the esophagus and then through tissue of the stomach at an oral side of the junction of the stomach and the esophagus with a needle provided outside of the endoscope which is not mechanically connected to the holding device and which is moveable outside of the endoscope relative to the endoscope; and passing a binding member through the tissue of the esophagus and the tissue of the stomach using the needle.
