Abstract
A tissue-fastening tool indwelling system includes: a sheath; a needle tube disposed in the sheath; a tissue-fastening tool including a wire having a coil region disposable in the needle tube in a stretched state and restorable to a coil shape with the same winding diameter outside the needle tube; a stylet connected to the wire; and a manipulation part for manipulating the stylet to advance the wire and rotate the sheath in a first direction. In a state where a distal end of the needle tube is proximal of the distal end of the sheath, the manipulation part is designed to operate such that the wire is delivered from the sheath by a length of one winding of the coil region per rotation of the sheath by less than one turn, and the protruding coil region biased to have a diameter larger than the winding diameter.
