Description
本発明は、ガイドワイヤを含む医療器具に関する。より詳細には、本発明は、マトリックスポリマー構造に埋め込まれ、精密な摩擦特性を有するガイドワイヤに関する。
様々な器具が医療用途、例えば血管内での使用のために開発されている。このような器具の中には、ガイドワイヤ、カテーテル、及び各々特定の特徴及び特性を有するその他同様の器具が含まれる。
本発明は、医療器具(例えばガイドワイヤ)の代替の設計、材料、及び製造方法を提供する。少なくとも幾つかの実施形態においては、ガイドワイヤは、基端領域及び先端領域を有するコアワイヤ又はコア部材と、先端領域上に配置されるジャケットと、該ジャケット上に配置されるコイルとを備える。コイルは、コーティングを含んでいてもよく、或いはジャケット内に埋め込まれていてもよい。
