The tissue fastener indwelling device of the present invention includes a sheath having a lumen, a needle tip, a needle tube that is formed in a cylindrical shape and is arranged to protrude and retract from the distal end of the lumen, a distal end side region, A tissue fastener having a restoring force for restoring to a curved shape having a proximal side region and arranged in a state of being stretched inside the needle tube, and a base of the tissue fastener inside the needle tube A stylet coupled to an end, wherein the stylet is linearly advanced relative to the needle tube and the sheath until all of the distal region of the tissue fastener protrudes from the needle tube. And a second state in which the proximal end of the proximal end side region of the tissue fastener moves forward while rotating until it protrudes from the needle tube.本発明の組織締付具留置装置は、ルーメンが形成されたシースと、針先を有し、筒状に形成され、前記ルーメンの先端から突没自在に配置された針管と、先端側領域、基端側領域を有する湾曲形状に復元する復元力を有し、前記針管の内部に引き延ばされた状態で配置された組織締付具と、前記針管の内部で前記組織締付具の基端部に連結されたスタイレットと、を備え、前記スタイレットは、前記組織締付具の前記先端側領域の全てが前記針管から突出するまで前記針管および前記シースに対して直進する第１状態と、前記組織締付具の前記基端側領域の基端が前記針管から突出するまで回動しながら前進する第２状態と、を有する。
