    摘要: A tissue fastener production method of clamping two living tissues together by bringing the two living tissues into close contact includes the following steps: fixing one end of a wire material made of a metal to a shaft body, and winding the wire material around an outer periphery of the shaft body while twisting the wire material round an axis of the wire material, thereby forming a coil on which a predetermined force is exerted in the winding direction; heat treating the wire material to impart superelasticity thereto; and deforming the wire material to which the superelasticity is imparted in a range in which the wire material is elastically deformable, and reversing the winding direction of the coil in a direction reverse to the winding direction of the coil wound in the step of forming the coil so as to obtain an initial tension corresponding to the predetermined force.

    摘要: The applicator related to the present invention is provided with a flexible sheath longer than the overall length of an instrument channel of a flexible endoscope; an operation part used outside the instrument channel; a deployed section that can be made to protrude from the front end of the sheath by operating the operation part and to pierce a tissue; a tissue fastening tool made of a superelastic wire formed in coil shape and housed inside the deployed section in a substantially extended condition; and a pusher that pushes out the tissue fastening tool from the deployed section when the operation part is operated.
