Description
膜状のグラフト材から構成される管状体と、前記管状体を支持するステントと、を備えるステントグラフトにおいて、
前記管状体に開窓が形成されており、
前記開窓の縁周辺にレントゲンマーカーが設置されている、
ことを特徴とする。
前記開窓の四方に前記レントゲンマーカーが設置されていることが好ましい。
前記開窓が前記弓部大動脈から分岐する左鎖骨下動脈、左総頸動脈及び腕頭動脈の開口部を囲むように形成されていることが好ましい。
図を参照しつつ、実施の形態1に係るステントグラフトについて説明する。本実施の形態に係るステントグラフト10は、上行大動脈のバルサルバ洞から腕頭大動脈にかけて内挿されるものであり、主に、上行大動脈の大動脈解離の治療に用いられるものである。
図を参照しつつ、実施の形態2に係るステントグラフトについて説明する。ここでは、弓部大動脈瘤の治療に用いるステントグラフトを例にとり説明する。実施の形態に係るステントグラフト40は、図6(A)、(B)に示すように、開窓42を有する管状体41と、ステントSTと、レントゲンマーカーRMを備える。
