Description
Claims (6)
- 編組骨格を有する管腔内人工器官であって、該骨格(6)が、編織された生体適合性のある金属ワイヤからなる複数の層(8、10、12)から本質的になり、カバー層を有しておらず、これらの層(8、10、12)の各々がワイヤ(14)からなる2本のプライにより形成されており、この2本のプライはそれぞれ右螺旋と左螺旋であり、かつこの2本のプライは編織されて格子を形成しており、ある層(8、10、12)に含まれる複数のワイヤ(14)が隣接する層(8、10、12)のうちの少なくとも1つの層の格子に組み込まれており、該骨格は編組された後に熱処理により相転移を生じさせて焼入れされ、該管腔内人工器官の側壁に多孔性を有し、動脈瘤のある血管内に設置した場合に該動脈瘤内の圧力波を低下させることによりこの側壁を通過する血流学的な対流を拡散流へと変換することを特徴とする、前記管腔内人工器官。
- 上記ワイヤ(14)の素材が、ステンレス鋼、Phynox(登録商標)、Elgiloy(登録商標)、チタンおよびその合金、ならびにNitinolからなる群から選択されることを特徴とする、請求項1に記載の管腔内人工器官。
- 上記骨格(6)が太さの異なる金属ワイヤ(14)を含むことを特徴とする、請求項1または2に記載の管腔内人工器官。
- 上記骨格(6)が太さの異なるワイヤ(14)により形成された層を含むことを特徴とする、請求項3に記載の管腔内人工器官。
- 上記骨格が種類の異なる金属ワイヤ(14)を含むことを特徴とする、請求項1〜4のいずれか1項に記載の管腔内人工器官。
- 上記ワイヤ(14)の太さが少なくとも25〜60μmの範囲内にあることを特徴とする、請求項3〜5のいずれか1項に記載の管腔内人工器官。
