Description
1.発明の分野
本発明は、動脈瘤治療装置に関し、より詳細には、グラフト材料とステントとの間の相対運動を排除するために、グラフト材料を管腔内足場もしくはステントに取り付ける装置および方法に関する。
動脈瘤は、全身コラーゲン合成の欠陥もしくは構造的欠陥により通常生じる、動脈壁部の1つまたは複数の層の異常な膨張である。腹部大動脈瘤は、2つの腸骨動脈のうち一方もしくは双方の中または近くに、あるいは腎動脈の近くに通常位置する、大動脈の腹部部分における動脈瘤である。動脈瘤は、罹患した大動脈の腎臓下部分、例えば腎臓の下、でしばしば生じる。胸部大動脈瘤は、大動脈の胸部部分における動脈瘤である。治療せずに放っておくと、動脈瘤は破裂する可能性があり、大抵、急な致命的出血を引き起こす。
本発明は、簡潔に前述したように、システムの構成要素間の相対運動を示す、現在用いられている動脈瘤治療装置に付随する欠点を克服する。
図1を参照すると、動脈瘤治療システムの固着・密封構成要素100の例示的な実施形態が示されている。固着・密封構成要素100は、本体部分(trunk section)102と、2つの脚部104、106を含む分岐部分と、を含む。以下に詳細に説明されるグラフト材料108は、本体部分102の少なくとも一部、および脚部104、106のすべてに付着されている。グラフト材料は、任意の数の手段により取り付けられてよい。例示的な実施形態では、グラフト材料108は、縫合糸110により、下にある構造体の様々な部分に取り付けられる。例示されたように、グラフト材料108は、本体部分102の端部における連続的なステッチパターンで、また、他の所でのシングルステッチにより、付着されている。あらゆるステッチパターンが用いられてよく、また、下にある構造体にグラフト材料108を接続するためにステープルなどの他の装置が用いられてよいことに注意することが重要である。縫合糸110は、非常に耐久力があり耐磨耗性であることが好ましい、あらゆる適切な生体適合性材料を含むことができる。
