Description
人工心臓弁(prosthetic heart valve)は、患者の問題のある生体弁(human valves)の代替となることができる。例えば、人工弁の外周のまわりに延びて取り付けられている縫合糸リング(sewing rings)又は縫合カフ(suture cuffs)を有するワンピースの弁が提案されている。さらに、弁部材とは別体の縫合糸リングを有する複数部品の弁も提案されている。いずれの型の人工弁の縫合糸リングも、目的部位の中、即ち、自然の心臓弁(natural heart valve)が取り除かれた心臓の環状部(annulus)の中に取り付けるためには時間も手間もかかることになり得る。
本発明は、患者に移植することができる心臓弁、特に、一体に組み立てることができる複数部材の心臓弁アセンブリと、そのような移植を行うための装置と、移植するための方法とに関する。
図面を参照すると、図1A及び2Aは、ガスケット部材12及び弁部材14の1つの態様を示しており、これらを組み合わせることによって、例えば、図6A及び6Bに示す心臓弁アセンブリ10を提供することができる。
