- 補綴心臓弁のための裁縫リングであって、
流入−流出の方向を定義する軸の周りに配列された輪状部材であって、該輪状部材の全体が縫合糸を通し、該輪状部材は、実質的に平らな流入端を有し、かつ、流出端を有し、該流出端は、ちょうど2つの間隔を空けられた部分を含み、該ちょうど2つの間隔を空けられた部分は、該輪状部材の周囲でより短い距離に約120度間隔を空けられており、かつ、該流出端の隣接部分に対して軸方向に隆起しており、該流出端は、ちょうど2つの軸方向に隆起した部分の間のより長い距離の周囲で実質的に平らである、輪状部材と、
該輪状部材を囲むファブリックのカバーと
を含む、裁縫リング。 - 前記軸方向に隆起した部分のそれぞれは、前記流出端の前記隣接部分から上向きに、前記輪状部材の最も大きな軸方向の寸法の約50%の高さまで緩やかに湾曲する、請求項1に記載の裁縫リング。
- 前記輪状部材の前記最も大きな軸方向の寸法は、約4mmである、請求項2に記載の裁縫リング。
- 前記輪状部材は、前記軸方向に隆起した部分の間のより短い距離の周囲に位置している該軸方向に隆起した部分の間の中間点において、該中間点と正反対に向かい合う位置よりも柔軟ではない、請求項1に記載の裁縫リング。
- 前記輪状部材は、複数の放射状の壁を有するモールドされたポリマーを含み、該複数の放射状の壁は、該放射状の壁間の空間を定義し、
該放射状の壁は、前記軸方向に隆起した部分の間のより短い距離の周囲に位置している該軸方向に隆起した部分の間の中間点において、該中間点と正反対に向かい合う位置における該放射状の壁よりも厚い、請求項1に記載の裁縫リング。 - 前記輪状部材は、複数の放射状の壁を有するモールドされたポリマーを含み、該複数の放射状の壁は、該放射状の壁間の空間を定義し、
該空間は、前記軸方向に隆起した部分の間のより短い距離の周囲に位置している該軸方向に隆起した部分の間の中間点において、該中間点と正反対に向かい合う位置における該空間よりも小さい、請求項1に記載の裁縫リング。 - 前記ファブリックは、前記軸方向に隆起した部分の間のより短い距離の周囲に位置している該軸方向に隆起した部分の間の中間点において、該中間点と正反対に向かい合う位置よりもしっかりと巻かれている、請求項1に記載の裁縫リング。
- 前記裁縫リングは、前側面と後ろ側面との周りに間隔を置いた2つの三角を有する僧帽状輪における移植のための、僧帽心臓弁の構成要素を形成し、
前記輪状部材は、前側および後ろ側を有し、
該輪状部材は、その前側の周りにおいて、その後ろ側の周りよりもよりコンプライアンスを有する、請求項1に記載の裁縫リング。 - 前記輪状部材は、連続した円周状の内壁および外壁を含み、複数の放射状の壁が、該内壁および該外壁の間に延びている、請求項1に記載の裁縫リング。
- 前記軸方向に隆起した部分のそれぞれは、前記外壁から上向きに突出している外側の部分的にチューブ状の壁部分によって形成され、該外側の部分的にチューブ状の壁部分は、軸方向の高さについて、前記内壁から上向きに突出している反対の内側の部分的にチューブ状の壁部分と一致し、該内壁および該外壁の間の前記放射状の壁の軸方向の高さは、該部分的にチューブ状の壁部分の軸方向の高さと一致する、請求項9に記載の裁縫リング。
- 前記外壁は、実質的に円錐状であり、前記輪状部材の前記流入端上の前記内壁と接し、該内壁および該外壁の組み合わせは、前記流入方向において面する中空でない壁を定義する、請求項10に記載の裁縫リング。
- 前記裁縫リングの外面上のファブリックのカバー上に提供された位置マーカーをさらに含み、該位置マーカーは、前記軸方向に隆起した部分の頂部を意味する、請求項1に記載の裁縫リング。
- 前記輪状部材は、巻かれたファブリックから形成され、該ファブリックは、前記軸方向に隆起した部分の間の中間点においてよりきつく巻かれており、それにより、該中間点と正反対に向かい合う位置よりも柔軟ではない、請求項1に記載の裁縫リング。
- 前記輪状部材は、不織のポリエステルのフェルトの詰め物で形成され、該ポリエステルのフェルトは、前記軸方向に隆起した部分の間の中間点においてよりしっかりと詰め込まれており、それにより、該中間点と正反対に向かい合う位置よりも柔軟ではない、請求項1に記載の裁縫リング。
