Abstract
Description
本願において、すべての数値は、明示的に示されているか否かに関わらず、「約」という語によって修飾されるものと見なされる。「約」という用語は、一般に、当業者が列挙された値と同等であると見なす(すなわち、同じ機能または結果を有する)一連の数を指す。多くの場合において、「約」という語は、最も近い有効数字に丸められる数を含み得る。
本明細書および添付された特許請求の範囲においては、単数形の「1つの(a)」、「1つの(an)」および「その(the)」は、内容が明らかに他に規定していない限り、複数の指示対象を含む。本願および添付された特許請求の範囲においては、「または(or)」という語は、内容が明らかに他に規定していない限り、一般にその意味において「および/または(and/or)」を含んで使用される。
経皮経管冠動脈形成術のような低侵襲性心臓インターベンションは世界中で広く用いられている。これらの手技は、ガイドカテーテルの使用を含み得る。例えば、ガイドカテーテル10は、図1Aに示すように、大動脈Aのような血管を介して、(例えば左および/または右)冠状動脈CAの開口Oに隣接した位置に進められる。そのように配置されると、治療カテーテル(例えばバルーンカテーテル、ステントデリバリーシステムなど)は、ガイドカテーテル10を介して、冠状動脈CA内において標的位置まで進められて、そこで適当な心臓インターベーションを実施するために用いられる。
