TUBULAR TREATMENT IMPLEMENT INDWELLING APPARATUS

To reduce the number of times of insertion operations into a blood vessel and removal operations from the blood vessel per surgery.SOLUTION: A tubular treatment implement indwelling apparatus 100 for indwelling a plurality of stent grafts SG,... that can be expanded in a radial direction in a blood vessel includes: a sheath 1; a long shaft-like member 2 configured so as to advance and retreat along an axial direction of the sheath inside the sheath, which can lock the plurality of stent grafts; and a discharge control part 3 for individually releasing the locking of the plurality of stent grafts by the shaft-like member when the sheath and the shaft-like member are relatively displaced, and discharging the stent grafts from inside the sheath.SELECTED DRAWING: Figure 1 【課題】一回の手術あたりでの血管内への挿入作業、抜去作業の回数を減少させる。【解決手段】径方向に拡張可能な複数のステントグラフトＳＧ、...を血管内に留置するための管状治療具留置装置１００であって、シース１と、シースの内側にて当該シースの軸方向に沿って進退可能に構成され、複数のステントグラフトを係止可能な長尺の軸状部材２と、シースと軸状部材とが相対的に変位されることで軸状部材による複数のステントグラフトの係止を個別に解除して、シースの内側からステントグラフトを放出するための放出制御部３と、を備える。【選択図】図１
