Abstract
Description
細長い部分と、細長い部分から半径方向に延びる下流側のループ状部分、上流側のループ状部分、および中間のループ状部分と、中間のループ状部分に取り付けられた弁とを含む血管装置を準備し、
目標血管内に送達装置を挿入し、送達装置内の挿入位置に血管装置を挿入し、挿入位置で、下流側状部分、上流側部分、および中間のループ状部分は、低減された横断寸法を有し、
送達装置から血管装置を露出させ、血管装置を露出させることにより、下流側部分、上流部分、および中間のループ状部分は、拡張位置に移動することが可能になり、中間のループ状部分は、血管の内壁に係合し、血管の径に合わせて自動的に調節される、ことを特徴とする静脈弁不全を治療するための方法を提供する。
12、72 弁支持体
48、75 置換弁
