摘要：
Stented prosthetic heart valves comprising a stent frame having a compressed arrangement for delivery within a patient's vasculature and an expanded arrangement for deployment within a native heart valve. The stented prosthetic heart valves including a paravalvular leakage prevention or mitigation wrap that encircles a stent frame and is formed of a flexible material having a variable diameter defined by a greatest distance between the wrap and the stent frame. The wrap further includes a first end coupled to the stent frame and an opposing second end that is not coupled to the stent frame, wherein the wrap can selectively enlarge its diameter in situ via movement of the second end. Devices for and methods of selectively deploying the wrap are also disclosed.
