PROBLEM TO BE SOLVED: To provide a blood vessel treatment assembly capable of effective treatment without a foreign matter left within a blood vessel and with minimized invasiveness.SOLUTION: A blood vessel treatment assembly 100 comprises: a catheter 110 which has a vessel closing part 112 expandable and contractable and has at least one lumen 115 formed communicating from the distal end side to the proximal end side of the vessel closing part a cut off tool 120 which is insertable to the lumen, and capable of circumferentially cutting off a vessel 1 at the distal end side of the vessel closing part a fold back device 130 which is insertable to the lumen, curves to fold back to the proximal end side at the distal end side of the vessel closing part, and is capable of turning the vessel wall 1C of the end of a cut off vessel to the outside of the vessel and a treatment tool 140 which is insertable into the lumen and is capable of treating the surface of the vessel wall turned inside out.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】血管内に異物を残さず、かつ侵襲性をできるだけ抑えた効果的な治療が可能な血管治療アセンブリを提供する。【解決手段】血管治療アセンブリ100は、拡張・収縮自在な血管閉鎖部112を有するとともに、血管閉鎖部よりも先端側へ基端側から連通する少なくとも1つのルーメン115が形成されたカテーテル110と、ルーメンに挿通自在で、血管閉鎖部よりも先端側で血管1を周方向に切断可能な切断具120と、ルーメンに挿通自在で、血管閉鎖部よりも先端側で基端側に折り返すように曲がり、切断された血管の端部の血管壁1Cを血管の外側に反転させ得る折返し具130と、ルーメンに挿通自在で、内外反転した血管壁の表面を治療可能な治療具140と、を有する。【選択図】図1
