Description
本明細書に開示される任意の例に加えてまたは代えて、移動防止ループの少なくとも一部分が、中心長手軸に対して実質的に垂直に配向される。
本明細書に開示される任意の例に加えてまたは代えて、複数の第1のフィラメントと複数の第2のフィラメントとを織り合わせることが、複数の交点を画定する。
本明細書に開示される任意の例に加えてまたは代えて、溝は、複数の第1のチャネルのうちの隣接する第1のチャネルを接続する。
本明細書に開示される任意の例に加えてまたは代えて、医療用ステントを製造する方法が、円筒体と、円筒体から径方向外方に延びる複数の突出部とを備えるマンドレルを使用する工程であって、複数の突出部は、第1の方向に円筒体の周りをらせん状に延びる複数の第1のチャネルと、第2の方向に円筒体の周りをらせん状に延びる複数の第2のチャネルとを画定し、複数の突出部のうちの少なくともいくつかには、円筒体の周りを周方向に延びる溝が形成されている、工程と、複数の第1のチャネル内でマンドレルの周りに複数の第1のフィラメントを巻き付け、複数の第2のチャネル内でマンドレルの周りに複数の第2のフィラメントを巻き付けて、複数の第1のフィラメントと複数の第2のフィラメントとが織り合わされて医療用ステントの本体を画定するようにする工程とを備え得る。複数の第1のフィラメントのうちの少なくともいくつかは、複数の突出部のうちの形成された溝を含む少なくともいくつかの上に巻き付けられ得る。
本明細書に開示される任意の例に加えてまたは代えて、複数の突出部のうちの少なくともいくつかに形成された溝は、円筒体の周りを周方向に延びる。
すべての数値は、本明細書において、明示されているかどうかにかかわらず、「約」という用語で修飾されていると想定される。数値の文脈において「約」という用語は、一般に、記載された値と同等である(例えば、同じ機能または結果を有する)と当業者が考える数の範囲を指す。多くの場合、「約」という用語は、最も近い有効数字に丸められる数を含み得る。「約」という用語のその他の(例えば、数値以外の文脈における)使用は、別段に指定されない限り、明細書の文脈から理解され、それと整合するように、それらの通常の慣例的な定義を有すると想定されてよい。
