Embodiment Construction

[0015] Specific embodiments of the present application are now described with reference to the drawings, wherein like reference numerals designate identical or functionally similar elements. As used herein with reference to a prosthetic heart valve, the term "outflow" is understood to mean downstream in the direction of blood flow, and the term "inflow" is understood to mean upstream in the direction of blood flow. Although the present disclosure has been described with reference to preferred embodiments, workers skilled in the art will recognize that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure.

[0016] Certain aspects of the present disclosure relate to a transcatheter stented prosthetic heart valve delivery device that delivers a stented prosthetic heart valve (hereinafter referred to as a "prosthesis") in a compressed arrangement during delivery to a target site valve") and allow the prosthet...

Abstract

Stented prosthetic heart valves including a stent frame having a plurality of stent frame support structures collectively defining an interior surface, an exterior surface and a plurality of cells. The stented prosthetic heart valve further including a valve structure including valve leaflets disposed within and secured to the stent frame and defining a margin of attachment. The stented prostheticheart valve including one or both of an outer paravalvular leakage prevention wrap and an inner skirt for supporting the valve leaflets. In various embodiments, the outer wrap is positioned entirelyon one side of the margin of attachment. In embodiments including an inner skirt, the outer wrap and the inner skirt are on opposite sides of the margin of attachment such that the inner skirt and theouter wrap do not overlap. In other embodiments, the outer wrap includes a plurality of zones having varying thickness.

Description

Background technique [0001] The present disclosure relates to stented prosthetic heart valves having paravalvular sealing wraps. [0002] The human heart consists of four heart valves, which determine the path blood flows through the heart: the mitral, tricuspid, aortic, and pulmonary valves. The mitral and tricuspid valves are atrioventricular valves located between the atria and ventricles, while the aortic and pulmonary valves are semilunar valves located in the arteries that leave the heart. Ideally, the native leaflets of the heart valve move away from each other when the valve is in the open position and touch or "close" when the valve is in the closed position. Problems that can arise with the valve include: stenosis, when the valve does not open properly; and / or insufficiency or regurgitation, when the valve does not close properly. Stenosis and insufficiency may coexist in the same valve. The effects of valve dysfunction vary according to the severity of the diseas...
