Abstract
Description
長尺なワイヤ本体と、
前記ワイヤ本体の少なくとも先端側の部分に、その全周にわたって設けられ、生体内での前記ワイヤ本体の位置を示す機能を有するマーカとを備え、
前記マーカは、第1の線状部と第2の線状部とを互いに複数の箇所で交差させて、全体として格子状をなすような形状をなしていることを特徴とするガイドワイヤである。
前記マーカと前記ワイヤ本体との間には、中間層が形成されているのが好ましい。
前記マーカは、前記コイルよりも基端側に配置されているのが好ましい。
図1は、本発明のガイドワイヤの第1実施形態を示す部分縦断面図、図2は、図1中の一点鎖線で囲まれた領域[A]の縦断面図、図3は、図1に示すガイドワイヤにおけるマーカの斜視図、図4は、図3中のB−B線断面図、図5は、図1に示すガイドワイヤをその軸周りに回転させたときのマーカの変化過程を示す図、図6は、図1に示すガイドワイヤをその軸方向に沿って移動させたときのマーカの変化過程を示す図である。なお、以下では、説明の都合上、図1、図2、図5および図6中(図7、図8も同様)の右側を「基端」、左側を「先端」と言う。また、図1中では、理解を容易にするため、ガイドワイヤの長さ方向を短縮し、ガイドワイヤの太さ方向を誇張して模式的に図示しており、長さ方向と太さ方向の比率は実際とは異なる。
図5(a)は、ガイドワイヤ1を回転させる前の状態を示す。そして、ガイドワイヤ1を図中の矢印方向へ所定量(角度)回転させと、図5(b)に示す状態となる。
図6(a)は、ガイドワイヤ1を移動させる前の状態を示す。そして、ガイドワイヤ1を図中の矢印方向へ所定量(距離)移動させと、図6(b)に示す状態となる。
第1の線状部121および第2の線状部122のうち、第1の線状部121を第2の線状部122よりも先行して形成する。
図7は、本発明のガイドワイヤの第2実施形態を示す側面図である。
このような構成は、交差部123の形成数を比較的多く設定したい場合に有効である。
図8は、本発明のガイドワイヤの第3実施形態を示す側面図である。
