Embodiment Construction

[0028] Specific embodiments of the present invention are now described with reference to the drawings, wherein like reference numerals indicate identical or functionally similar elements. In the following description, the terms "distal" and "proximal" are used with respect to position or direction relative to blood flow. "Distal" and "distally" refer to a position in the downstream direction relative to the direction of blood flow. "Proximal" and "proximally" refer to positions in the upstream direction relative to the direction of blood flow.

[0029] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Although the embodiments herein are described in the context of treating a native heart valve, such as the aortic valve, the invention can also be used in other heart valve locations and any other body passage where it is deemed useful. Furthermore, there is no intention to b...

Abstract

The invention provides a transcatheter valve prosthesis. The transcatheter valve prosthesis comprises a support, a prosthetic valve component and a perivalvular leakage prevention component. The perivalvular leakage prevention member is coupled to the stent and includes an inner skirt, an outer wrap, a cavity, an opening, and a one-way valve. The inner skirt is disposed on an inner surface of the stent and has an inflow end and a downstream end. The outer wrap is disposed about an outer surface of the stent and has an inflow end coupled to the inflow end of the inner skirt and a downstream end. The cavity is formed between an outer surface of the inner skirt and an inner surface of the outer wrap. An opening is provided between the inner skirt and the outer wrap. The one-way valve includes a flap at the opening configured to open to allow blood to flow into the cavity but prevent blood from flowing out of the cavity.

Description

technical field [0001] The present invention generally relates to prostheses for intervascular delivery. More specifically, the present invention relates to valvular prostheses having paravalvular leak prevention components that help prevent paravalvular leaks at deployed valvular prostheses. Background technique [0002] The human heart is a four-chambered muscular organ that provides blood circulation through the body during the cardiac cycle. The four main chambers contain the right atrium and right ventricle, which provide pulmonary circulation, and the left atrium and left ventricle, which supply oxygenated blood received from the lungs to the rest of the body. To ensure that blood flows in one direction through the heart, there are atrioventricular valves (tricuspid and mitral) between the junctions of the atria and ventricles, and semilunar valves (pulmonary and aortic) that regulate passage to the lungs and The outlet of the ventricles elsewhere in the body. These...
