Abstract
Description
図29を参照すると、健康な僧帽弁10が示されており、前尖12aと後尖12bと呼ばれる2つの天然の(個体自身が初めから有していた元の)弁尖12によって形成されている。健康な僧帽弁10では、収縮期の間、弁尖12は血液の逆流に対して弁開口部を閉じるように接合する。図30は、例えば、虚血または左心室膨張の結果として弁尖12が接合できない機能不全の僧帽弁の一例を示す。隙間14が両弁尖表面の間に残っており、収縮期に弁開口部を通る血液の逆流をもたらす。
これに加えて、またはこれに代えて、本開示のいくつかの他の実施形態は、生体吸収性材料を含むプロテーゼ腱索(僧帽弁腱索プロテーゼ)を提供し得る。
上記または他の実施形態のいずれかに加えて、本開示の他の実施形態は、生体吸収性材料を含む血管閉鎖装置(VCD)を提供し得る。
