Description
本出願は、米国仮出願シリアル番号第62/220,895号(出願日:2015年9月18日、タイトル:「血管プロテーゼ」)の利益を主張する。本明細書は、同文献全体を参照として含むものである。
血管プロテーゼ(例えば、ステントおよび/またはステントグラフト)は、多様な理由のために血管系内において用いられる。例えば、これらは、血管を支えて開けたままにすること、プラーク蓄積を治療すること、血管の一部を置換えること、血流を標的領域から離れるように迂回させること、他の医療デバイスの導入のためにスキャフォールドまたはルーメンを提供すること、または他の多様な理由のために用いることができる。
本発明の一局面は、編まれたステントのワイヤ端部から発生した比較的鋭利なまたは粗い端部を低減させるかまたは排除する技術および実施形態に関する。例えば、ステントのワイヤ端部を、エンドキャップ内で停止させるか、またはステントのワイヤを曲げ、溶接して停止させることができる。
以下、本発明の特定の実施形態について、添付図面を参照しつつ説明する。しかし、本発明は、多数の異なる形態で具現化が可能であり、本明細書中に記載の実施形態に限定されるものとして解釈されるべきではなく、これらの実施形態は、本開示を網羅的かつ完全なものとして、当業者に対して本発明の範囲を伝達するために提供されるものである。添付図面中に記載される実施形態の詳細な説明において用いられる用語は、本発明を限定することを意図するものではない。図面中、類似の参照符号は、類似の要素を指す。
