Description
これらのおよびその他の利点は、複数の相互連結された双安定セルを備える螺旋状の本体を有する血管プロテーゼを提供することによって達成される。各双安定セルは、径方向に外側に向けられるが任意の中間の位置で不安定な力に曝された場合に、薄いストラットが安定した折りたたんだ位置と安定した拡張した位置の間でスナップするように、薄いストラットにその端部で接合される厚いストラットを備える。隣接するセルは螺旋状構造を形成するために互いに接合され、セルの薄いストラットおよび厚いストラットが全体的に螺旋の長手方向軸に対して整列する。好ましくは、プロテーゼは、ニッケル−チタンのような形状記憶合金を含み、さらに薬品またはその他の生物活性剤を送達する生分解性ポリマー被覆を備えることができる。
次に図10Aおよび10Bを参照すると、本発明の血管プロテーゼの別の実施形態の一部分が示される。前述の実施形態と同様に、プロテーゼ40が図10に巻きを解かれかつ平坦にされて示されるが、使用に際しては、それは螺旋構造を形成するために巻かれる。プロテーゼ40は、ブリッジ42によって連結された複数の双安定ユニット・セル41を備える。各ユニット・セル41は、その端部で厚い弓状ストラット44に連結された薄い弓状ストラット43を備えてそれぞれ、遠位端部45および近位端部46を形成する。図10に示されるように、ブリッジ42は1つのセルの厚いストラット44を隣接するセルの薄いストラット43に連結する。あるいは、薄いストラットまたは厚いストラットの隣接する対の間に交互に並ぶブリッジが延出するように、隣接するセルは逆にすることができる。
第1の発明は、複数の巻きを有する螺旋状の本体を備えるプロテーゼであって、前記複数の巻きがブリッジ要素によって相互連結された双安定セルを備え、各前記双安定セルが厚いストラットに連結された第1の端部および第2の端部を備える薄いストラットを有し、前記薄いストラットが安定した完全に折りたたんだ構成と安定した完全に拡張した構成のみの間を移行するように構成されたプロテーゼである。
第2の発明は、少なくとも1つの終端の巻きをさらに備え、前記終端の巻きが、前記プロテーゼが展開された場合に環状構造を画成する追加のユニット・セルを備える、プロテーゼである。
第3の発明は、前記追加のユニット・セルのうちの少なくともいくつかが双安定セルである、プロテーゼである。
第4の発明は、前記薄いストラットが第1の厚さを有し、前記厚いストラットが第2の厚さを有し、前記第2の厚さに対する前記第1の厚さの比率が1:2と1:5の間である、プロテーゼである。
第5の発明は、前記薄いストラットおよび前記厚いストラットが前記螺旋状の本体の長手方向軸に平行な方向に細長くされた、プロテーゼである。
第6の発明は、前記薄いストラットの前記第1の端部が前記ユニット・セルの遠位端部で前記厚いストラットに連結され、前記薄いストラットの前記第2の端部が前記ユニット・セルの近位端部で前記厚いストラットに連結され、前記プロテーゼが展開された場合に、前記螺旋状の本体の1つの巻きの前記ユニット・セルの前記近位の端部が前記螺旋状の本体の隣接する巻きの前記ユニット・セルの前記遠位端部に隣接して配置される、プロテーゼである。
第7の発明は、前記プロテーゼが展開された場合に、前記螺旋状本体の1つの巻きの前記ユニット・セルの前記近位端部と、前記螺旋状本体の前記隣接する巻きの前記ユニット・セルの前記遠位端部との間に間隙が形成されるように、前記螺旋状の本体のピッチが選択される、プロテーゼである。
第8の発明は、記プロテーゼが展開された場合に、前記螺旋状本体の1つの巻きの前記ユニット・セルの前記近位端部が、前記螺旋状本体の前記隣接する巻きの前記ユニット・セルの前記遠位端部から円周方向にオフセットするように、前記螺旋状の本体の前記ピッチが選択される、プロテーゼである。
第9の発明は、前記薄いストラットと前記厚いストラットが、それぞれ弓形を有する、プロテーゼである。
第10の発明は、各ブリッジ要素が、1つの双安定セルの薄いストラットを隣接する双安定セルの厚いストラットに連結する、プロテーゼである。
