Description
外側軸130が送達系のハブに関して近位に引き込められると、自己拡張型分岐プロテーゼ100が解放されて、その拡張形態を呈することを可能にする。図8に記載の送達系を、密封アセンブリ110が送達系のハブに関して管状本体102よりも近位にあるように取付けられた分岐プロテーゼ100とともに利用した時に、管状本体102は、外側軸130が矢印146の方向に引き込められるにつれて、最初に展開または露出される。より具体的には、最初に、管状本体102が展開し、続いて、環状フランジ112が展開し、最後に、密封スリーブ114が解放されて、その巻き上げられた、またはコイル状の形態を呈することを可能にする。この様態では、環状フランジ112は、最初に、展開した主プロテーゼの外面に沿って開窓の外辺部を押圧する。次いで、密封スリーブ114は、展開して、展開したフランジ112と並列して、展開した主プロテーゼの内面に沿って、開窓の外辺部に対して巻き上がる。一実施形態では、密封スリーブが、密封スリーブの近位端がフランジに向かって少なくとも270度ターンするすなわち折り返されるように、コイルに巻き上げられている。また、いくつかの実施形態では、密封スリーブの近位端が、フランジに向かってターンするすなわち折り返され密封スリーブの近位端が密封スリーブの近位端より遠位側の部分に接触するように、コイルに巻き上げられている。図8に記載の送達系は、図11〜図13に関して本明細書で説明されるように、分岐プロテーゼ100を、展開した主血管プロテーゼを通して、標的分岐血管に送達する時に有用であり得る。例えば、展開した主血管プロテーゼは、大動脈弓、下行大動脈、または腹部大動脈内に位置してもよく、分岐プロテーゼ100は、大腿動脈の分岐を通して脈管構造の中に導入されてもよい。
