Abstract
Description
本発明の更に別の態様では、逆棘の応力分散領域は、コイル巻きループ曲げ部、U字型曲げ部、又は取り付け点の遠位側に一連の曲げ部を設けて逆棘に可撓性を加え、それによって曲げ疲労と逆棘破損の危険性を低減している。逆棘は、更に可撓性を加えるためにコイル巻きループ曲げ部(又は他の型式の曲げ部)と自由螺旋形巻き部の両方を設けてもよい。
のワイヤーを使用するのが好ましい。ワイヤーが剛すぎると、血管を損なう恐れがあり、血管壁に巧く沿わず、展開前に送出システム内に装填する際に、装置の外形が大きくなる。
図78−79は、サブ部分205を使って、閉じたフレームを組み立てる別の実施形態を示しており、この場合、4つのL字型のサブ部分214、220、221、222を、4つの側辺13それぞれで組み合わせて、閉じた外周62を形成している。図示の実施形態では、端部217の内2つだけを使って逆棘17、18を形成しているが、L字型のサブ部分214、220、221、222の何れかの脚部を長くして、その脚部が閉じた外周62超えて伸張するようにすることによって、追加の逆棘を形成してもよい。これら図示の構成だけでなく、例えば、4つ以上の側辺を有するフレームを作る場合、3つのサブ部分205、又は4つを越えるサブ部分205を有する他の構成も可能である。
