Claims (1)
- 【特許請求の範囲】 1.血管などの管へ経管挿入するためのバルーンカテーテル上に備え付けるため の、円筒形スリーブの形にマンドレルに巻き付けられるへビ状平坦リボンの形に 曲げられた細いワイヤから形成される半径方向に伸張可能なステントで、その改 良点はステントを形成するワイヤがPt−Ir又はAu−Niからなるグループ から選択される合金からなり、該合金は約155,000から175,000PSIの引っ張り 強度を示すことによって特徴づけられるものである。 2.該合金が約90wt%のPt及び10wt%のIrからなる、請求の範囲1 に記載のステント。 3.血管内移植用の半径方向に伸張可能なステントであって、前後方向軸を有す る円筒を定義する2つの端部分と複数の中間部分を含む、複数のヘリックス状に 並べられた周回状部分を含み、上記の周回状部分を備える連続したワイヤで形成 される上記円筒は、上記軸に沿って接触するコンタクトを持って空間的に配置さ れており、 上記周回状部分の各々は、半径方向の伸張可能性を上記の部分に与える伸張 可能セグメントを有し、これにより上記の部分は上記挿入円周よりも大きい伸張 されていない挿入円周を有し、 上記伸張可能セグメントは、伸張されていない状態では、上記の周回状部分 の周りに交互に反転される涙滴形状の要素であり、各要素はべースと、ステント が伸張されていない状態にあるとき共通の頂点に集まる一対の脚とを含み、 上記伸張可能セグメントは、伸張された状態では、上記の周回状部分の周り に交互に反転されるU字型の要素であり、 上記端部分の1つは、周回状部分の背後を通り、ループにされるか、又は前 もって選択された複数の位置でヘリックスに巻き付けられる自由端を有し、これ により寸法安定性を提供し、かつ半径方向伸張の間の、ステントの軸方向の伸張 を防ぐようにされているもの。 4.ステントを形成するワイヤがPt−Ir又はAu−Niからなるグループか ら選択される合金からなり、該合金は約155,000から175,000PSIの引っ張り強 度を示す、請求の範囲3に記載のステント。5.該合金が約90wt%のPt及 び10wt%のIrからなる、請求の範囲4に記載のステント。
