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。
本発明の一実施形態は、基端領域及び先端領域を有するコア部材を提供する工程と、前記コア部材の先端領域上にほぼ平滑な外面を有するポリマージャケットを配置する工程と、張力を付与しつつコイルを前記ポリマージャケット上に巻回する工程と、これに続いて、前記コイルの張力が緩和されてジャケット外面がコイルの近接するコイル巻回部間に侵入するように前記ジャケットを加熱する工程と
を含む医療器具の製造方法を提供する。
本発明の一実施形態は、基端領域及び先端領域を有する長尺状コア部材と、前記コア部材の先端領域上に配置され、かつ基端部分及び先端部分を有するポリマージャケットと、前記ポリマージャケットの基端部分上に配置される、ある輪郭を有する内面を有するコイルとを備え、コイルがポリマージャケットに直接的に結合されることなく、コイルの一部がポリマージャケットに埋め込まれることと、ポリマージャケットが、コイルの内面の輪郭の少なくとも一部の形状に合致することとを特徴とする医療器具を提供する。
以下、図面に基づき説明する。なお、各図面において、類似する要素には類似する符号を付す。詳細な説明及び図面は、特許を請求する発明の実施形態を例示するものである。
