Description
本願は、2010年9月30日に出願した米国特許仮出願第61/388573号の利益を主張し、その内容全体を参照によって本書に援用する。
本開示は、大動脈弁の修復を含む用途に有用な楕円形の装着フレームに関する。特に、本開示は、大動脈弁輪中に直接挿置されるように設計された楕円形の弁輪内装着フレームに関する。また、本開示は、楕円形の弁輪内装着フレームの挿置および移植のための方法、並びに上行大動脈DACRON(登録商標)グラフトおよび心膜単一または複数尖補綴のような相補的装置も含む。
哺乳類の心臓は本質的に、化学機械的エネルギ変換器として機能するポンプである。代謝基質および酸素の化学エネルギは血圧の機械エネルギに変換され、心収縮中に心筋サルコメアによって流動する。該ポンプは、収縮期と呼ばれる収縮/駆出期および拡張期と呼ばれる弛緩/充満期を1〜2Hzの周波数で周期的に繰り返す。
発明者らは、健康なヒトの大動脈弁の高解像度マルチスライスコンピュータ断層撮影(CT)血管造影図を入手して解析した。1mmの軸線方向スライスを用いて、Mathematicaで10個の正常な大動脈根のCT血管造影図から弁構造物のx、y、およびz座標を生成した。弁葉および洞の座標の三次元最小二乗回帰を使用して、半球モデルと楕円モデルとを比較した。全ての根構造物の形状および寸法を評価した。
1.5の軸比(長軸/短軸または0.66の短軸/長軸の軸比)の楕円形の断面および10°外側に広がったポストを持つ現在記載した弁輪内装着フレームを子ウシで試験し、以下の詳述する通り有望な結果を得た。
Claims (12)
- a)端を有する複数の湾曲と;
b)内部領域を形成するために湾曲の各々の端を相互接続する複数の点と;
c)点の各々から上向きに延びる複数のポストと
を備えた大動脈弁用の弁輪内装着フレームであって、
点、湾曲の端、およびポストが、弁輪内装着フレームの垂直面から測定して5度〜15度の角度で弁輪内装着フレームの内部領域から外側に広がる縁領域を画定し、かつ弁輪内装着フレームが、長軸および短軸を有する楕円形の形状を有し、
短軸に対する長軸の比は1.2〜1.8である、弁輪内装着フレーム。 - 弁輪内装着フレームが3つの湾曲と、3つの点と、3つのポストを備える、請求項1に記載の弁輪内装着フレーム。
- 弁輪内装着フレームが2つの湾曲と、2つの点と、2つのポストを備える、請求項1に記載の弁輪内装着フレーム。
- 縁部領域が、弁輪内装着フレームの垂直面から測定して10度の角度で弁輪内装着フレームの内部領域から外側に広がる、請求項1に記載の弁輪内装着フレーム。
- 楕円の短軸に対する楕円の長軸の比は1.5である、請求項4に記載の弁輪内装着フレーム。
- 楕円の長軸の長さは10ミリメートルから35ミリメートルの間である、請求項1に記載の弁輪内装着フレーム。
- 楕円の短軸の長さは8ミリメートルから25ミリメートルの間である、請求項1に記載の弁輪内装着フレーム。
- 弁輪内装着フレームがプラスチック、高分子、金属、熱可塑性樹脂、樹脂、またはそれらの組み合わせを含む、請求項1に記載の弁輪内装着フレーム。
- 弁輪内装着フレームが金属を含む、請求項8に記載の弁輪内装着フレーム。
- 弁輪内装着フレームが金属線を含む、請求項9に記載の弁輪内装着フレーム。
- 弁輪内装着フレームがコーティングまたは被覆される、請求項1に記載の弁輪内装着フレーム。
- 弁輪内装着フレームが高分子タイプの繊維布でコーティングまたは被覆される、請求項11に記載の弁輪内装着フレーム。
