Description
ステントとは、概して、カテーテル技術によって体内血管の管腔に導入される円筒状の人工器官である。ステントは、自己拡張またはバルーン拡張することが可能である。バルーン拡張型ステントは、一般的に、体内の治療部位に進む前に、初期の大きな直径からより小さな直径へ捲縮される。捲縮する前に、バルーン拡張型ステントは、一般的に、カテーテルシャフト上の拡張可能なバルーンを覆うように置かれる。ステントが完全に捲縮された直径で製造される場合は、ステントは拡張されてバルーン上に捲縮される。安全性を確保するために、捲縮プロセスは、無菌の環境で行わなければならない。長年にわたり、滅菌野における手術中にステントをバルーン上に捲縮する試みがなされてきた。しかし、大部分のステントは、現在、工場において好適なバルーン上に「予め捲縮」されており、その後使用できる状態で医師に供給される。
