塞栓除去装置は、概して、可撓性ワイヤと、可撓性ワイヤと係合する繊維ベースの血塊係合構造または要素とを備えている。繊維ベースの要素は、概して、非自己拡張型構造の繊維の束を備えており、そこでは、繊維を、一端または両端においてアンカー等に固定することができる。本装置は、同様に可撓性ワイヤと係合する支持構造および/または作動器具をさらに備えることができる。支持構造は作動器具として機能しても機能しなくてもよい。可撓性ワイヤと係合する構成要素は、可撓性ワイヤの上を摺動することができ、または可撓性ワイヤに固定して接続される。ガイドカテーテル、マイクロカテーテルおよび/または吸引カテーテル等、1つまたは複数のカテーテルを用いて、処置を容易にすることができるが、ガイドカテーテルを、吸引カテーテルとして構成することも可能である。本技術分野において既知である要素等、装置、イントロデューサ、止血弁等の近位端を、患者の血管内への要素の導入を可能にするように配置することができ、ルアーロック取付具等のさまざまな取付具を、患者の外部の様々な構成要素を患者の血管内に誘導することによって、それらの構成要素を送達するために使用することができる。
血塊除去の処置は、概して、繊維ベースの血塊係合要素を血管内で血塊を通り越して送達すること、血塊を近位方向に引っ張ることと、血管から血塊を吸引することとを含む。プロセスは、血塊除去を容易にするために血塊を解体することをさらに含むことができる。血塊係合装置は、概して、先のセクションで説明した構造のうちのいずれをも含むことができる。処置は、血塊の除去中に塞栓として血塊の断片のいかなる放出も低減または排除するように設計されている。血塊の除去に続き、繊維ベースの装置は、場合によっては断片の除去を制限または防止する連続した吸引によって回収される。
可撓性ワイヤおよび血塊係合器具の繊維ベースの要素は、概して滅菌パッケージに合わせて包装される。好適な滅菌処置は本技術分野において既知であり、他の処置も開発され得る。システム全体のさらなる構成要素を合わせて包装してもしなくてもよい。たとえば、ガイドカテーテルの設計に応じて、別個に包装することができる従来の構成要素を用いてもよい。同様の問題は、システム全体の他の構成要素に関連する。概して、本システムで用いられる固有の構成要素を、便宜上合わせて包装することができる。
