摘要： A prosthetic heart valve includes an expandable stent and a leaflet assembly coupled to the expandable stent. The expandable stent is radially expandable from a first size for intraluminal delivery through a body passageway to a second size for implantation of the prosthetic heart valve in the body passageway. The leaflet assembly includes leaflets movable between an open position permitting flow past the expanded stent and a closed position substantially restricting flow past the expanded stent. Each of the leaflets is coaptable with each of the other leaflets in the closed position to define a coaptation region of about 15 percent to about 35 percent of the overall height of each of the plurality of leaflets.

摘要： A prosthetic heart valve includes a radially expandable stent and a plurality of leaflets. Each leaflet includes a coaptation portion, an arcuate edge, and a belly. The coaptation portion is movable relative to respective coaptation portions of the other leaflets. The acuate edge has a first end and a second end and is coupled to the stent. The belly extends from the arcuate edge to an axis defined by the first and second ends of the arcuate edge, wherein the ratio of the surface area of the belly to the outer cross-sectional area of the expanded stent is about 0.09 to about 0.16.
摘要翻译：假体心脏瓣膜包括可径向扩张的支架和多个传单。每个小叶包括接合部分，弓形边缘和腹部。接合部分可相对于其他传单的相应接合部分移动。顶端边缘具有第一端和第二端并且联接到支架。腹部从弧形边缘延伸到由弓形边缘的第一和第二端限定的轴线，其中腹部的表面积与扩张支架的外侧横截面积的比率为约0.09至约0.16。
