Abstract
【解決手段】 本発明の一実施形態では、ステントは、一連の近位の頂端と、一連の遠位の頂端と、少なくとも1つの画像形成要素とを備える。第一の縫合用の穴が画像形成要素の遠位側の位置でステントの表面に設けられ、第一の縫合用の穴は、ステントの一部分をグラフト材に結合する縫合糸を受け入れる。一連の遠位の頂端と第一の縫合用の穴とを備えるステントの遠位領域はグラフト材と重なっており、一連の近位の頂端と少なくとも1つの棘状部とを備えているステントの近位領域は、グラフト材を越えて近位に配置される。別の実施形態では、ステントグラフトは、グラフトと、第一のステントと、第二のステントとを備え、第一のステントの一連の近位の頂端の各々はグラフトの近位端の遠位側に配置され、第二のステントの一連の近位の頂端の各々はグラフトの近位端を越えて近位に配置される。
