Description
本発明の医療用ガイドワイヤは、遠位端側小径部と前記遠位端側小径部より外径の大きい近位端側大径部とを有するコアワイヤと、
前記コアワイヤの遠位端側小径部の外周に軸方向に沿って装着され、少なくとも先端部および後端部において、前記コアワイヤに固着されているコイルスプリングとを有する医療用ガイドワイヤであって、
前記コイルスプリングのコイル外径が０．０１２インチ以下であり、
前記コイルスプリングの先端部は、金含有はんだにより、前記コアワイヤに固着され、 金含有はんだによる先端硬直部分の長さが０．１〜０．５ｍｍであることを特徴とする。
ここに、「金含有はんだ」には、Ａｕ−Ｇｅ系はんだ、Ａｕ−Ｓｉ系はんだ、Ａｕ−Ｉｎ系はんだ、Ａｕ−Ｓｂ系はんだなどのＡｕ合金はんだおよびＡｕはんだが含まれる。
The medical guide wire of the present invention is a core wire having a distal end side small diameter portion and a proximal end side large diameter portion having a larger outer diameter than the distal end side small diameter portion,
A medical guide wire having a coil spring attached to the outer periphery of the small-diameter portion on the distal end side of the core wire along the axial direction, and having a coil spring fixed to the core wire at least at the front end portion and the rear end portion;
A coil outer diameter of the coil spring is 0.012 inches or less;
The tip of the coil spring is fixed to the core wire with gold-containing solder, and the length of the hardened tip of the gold-containing solder is 0.1 to 0.5 mm.
Here, “gold-containing solder” includes Au alloy solder such as Au—Ge solder, Au—Si solder, Au—In solder, Au—Sb solder, and Au solder.
