PROBLEM TO BE SOLVED: To provide a tube stent that can be taken out of a state indwelling in a lumen easily and safely.SOLUTION: A tube stent includes: a tube body 51 having openings 51a, 51b at its distal end and proximal end, respectively a flexible flap 52 the one end of which is connected to a tube body and the other end of which is provided so as to project to an oblique outside of the proximal end side of the tube body and a thread member 54 the one end of which is fit to a flap. The other end 54b of the thread member is pulled with forceps through an endoscope, and thereby the tube stent can be drawn out of a bile duct 73 while closing the flap.SELECTED DRAWING: Figure 11COPYRIGHT: (C)2017,JPO&INPIT【課題】管腔内に留置された状態から容易且つ安全に取り出せるようにする。【解決手段】その遠位端および近位端にそれぞれ開口51a,51bを有するチューブ本体51と、チューブ本体にその一端が接続され、他端が該チューブ本体の近位端側の斜め外側に突出するように設けられた可撓性のフラップ52と、フラップにその一端が取り付けられた糸部材54とを備える。糸部材の他端54bを経内視鏡的に鉗子等で引っ張ることにより、フラップを閉じつつ、チューブステントを胆管73から引き抜くことができる。【選択図】図11
