摘要:
A collapsible prosthetic heart valve (200) includes a stent (202) and a valve assembly (204). The stent (202) has an annulus section (240) with a relatively small cross-section, and an aortic section (242) with a relatively large cross-section. The valve assembly (204), including a cuff (206) and a plurality of leaflets (208), is secured to the stent (202) in the annulus section (240) such that the valve assembly (204) can be entirely deployed in the native valve annulus and function as intended while at least a portion of the aortic section (242) is held by the delivery device (1010) in a manner that allows for resheathing. The configuration of the prosthetic valve (200) is such that the valve leaflets (208) can fully coapt and the valve (200) can function properly even when the stent (202) and/or valve assembly (204) become distorted upon deployment or use.

可塌缩人造心脏瓣膜(200)包括支架(202)和瓣膜组件(204)。 支架(202)具有横截面相对较小的瓣环部分(240)和横截面相对较大的主动脉部分(242)。 包括套囊(206)和多个瓣叶(208)的瓣膜组件(204)在瓣环部分(240)中固定到支架(202),使得瓣膜组件(204)可以完全展开 天然瓣膜环和功能如预期的那样,同时主动脉部分(242)的至少一部分由递送装置(1010)以允许再护理的方式保持。 假体瓣膜(200)的构造使得瓣膜小叶(208)可以完全接合并且瓣膜(200)可以适当地起作用,即使当支架(202)和/或瓣膜组件(204)在展开时变得扭曲或 使用。
