Description
本願は、2007年8月8日に出願された米国仮出願番号第60/963,971号の利益を主張する。当該仮出願はその全体が引用により援用される。
この発明は、損傷した管、導管、または他の生理学的通路の修復のために、人間および動物の体内へ移植する、血管内人工器官装置およびそれを用いた血管内人工器官システムに関する。
この明細書全体を通し、この発明の大動脈または他の血管への適用を論じる際、人工器官に対する「遠位の」という用語は、血流に対してさらに下流にある場所、または、移植された場合に血流に対してさらに下流にある人工器官の一部を指すよう意図されている。「遠位に」という用語は、血流の方向にあること、またはさらに下流にあることを意味する。「近位の」という用語は、血流に対してさらに上流にある場所、または、移植された場合に血流に対してさらに上流にある人工器官の一部を指すよう意図されている。「近位に」という用語は、血流の方向とは逆の方向にあること、またはさらに上流にあることを意味する。
この発明は、請求項1に特定するような大動脈弓における移植のための血管内人工器官装置を提供する。
この発明の実施例を、例示のみのために、添付図面を参照して以下に説明する。
「管腔内の」という用語は、人間または動物の体内の管腔内部に見られる、または配置され得る物体を述べている。「血管内の」という用語は、血管内にある、または配置され得る物体を述べている。管腔は、既存の管腔、または外科的介入によって作り出された管腔であり得る。これは、血管、胃腸管の一部、胆管などの管、呼吸器系の一部などの管腔を含む。「人工器官装置」はこのため、これらの管腔のうちの1つの内部に配置され得る人工器官である。
