Description
説明される実施の形態は、埋め込み可能な医療装置および方法に関し、より特定的には、たとえば大動脈弁などの損傷した管腔内の弁の修復のための埋め込み可能な医療装置と、その医療装置を埋め込む方法と、に関する。
大動脈弁は、心臓と身体の他の部分との間の、一方向弁として機能する。血液は、心臓の左心室から大動脈弁を経由して大動脈へポンプ輸送され、その結果身体へ血液を供給する。心臓の収縮の間、大動脈弁は閉じられ、血液が心臓へ逆流するのを防止する。
本発明は、改良された管腔内補綴物、改良された大動脈弁、および、患者内の大動脈弁の改良された置換方法を提供することを求める。
いくつかの実施の形態では、第一ステントと第二ステントとの少なくとも一方は、編み組まれた瓶型ステントを含む。
本出願において、「近位」の語は、医療処置中に心臓に概して最も近い方向をいう。一方、「遠位」の語は、医療処置中に心臓から最も離れる方向をいう。
本特許出願は、2007年11月9日に出願され、「大動脈弁ステントグラフト」と題された米国仮出願第60/986908号の優先権の利益を主張し、当該仮出願の開示はその全体が引用により援用される。
