Description
本発明は、埋め込み型管腔内プロテーゼに関する。より詳細には、本発明は、分枝を含む動脈瘤の治療のための管腔内プロテーゼに関する。
血管内修復は、大動脈瘤を治療するための比較的新しい低侵襲技術であることが知られている。遠く離れた場所にある血管を経由して、金属製またはプラスチック製フレーム(ステント)で支持された不透過性チューブ(グラフト)を送達する。しかしながら、それが不透過性であるために、この技術は、動脈瘤が重要な分枝(例えば、冠動脈、上大動脈分枝、腎および中副腎動脈、内蔵動脈および内腸骨動脈)を含む動脈瘤修復には適用できない。さもなければ、分枝の閉塞を伴う重篤な合併症を引き起こす。
本発明の第1の目的は、分枝を含む動脈瘤を治療するために、血管内アプローチによって埋め込むことができる機器を提供することである。
本発明の他の特殊性および利点は、以下発展され、添付図面を参照する。
下記では、用語「埋め込み型」は、身体血管内のある箇所に位置決めされる医療機器の能力を指す。埋め込み型医療機器は、医療的介入の際に身体血管内に一時的に配置されるように(例えば、数秒、数分、数時間)、または身体血管内に永久的に留まるように、構成され得る。
SCR=Sw/St
によって定義される。ここで、「Sw」は、管腔内プロテーゼ1に構成されるワイヤ21によって被覆される実際の表面であり、および「St」は、壁に対して垂直に観察するときの、管腔内プロテーゼ1の壁の全表面積である。
