摘要:
A prosthetic heart valve (300) for replacing a native valve includes a collapsible and expandable stent (306) having a proximal end (302) and a distal end (304), and a valve assembly (308) including a plurality of leaflets (310), the valve assembly (308) being disposed within the stent. The heart valve (300) further includes a first plurality of elongated legs (320) coupled to the stent (306) and transitionable from an extended configuration to a relaxed configuration. A first sealing portion (322) connected to the first plurality of legs (320) forms a sealing structure (350) when the legs (320) transition to the relaxed configuration to reduce perivalvular leakage between the implanted valve and surrounding tissue.
