Problems solved by technology

[0011] Furthermore, proper fixation of a prosthetic heart valve replacing a diseased native heart valve is often very complicated due to, for example, calcification of the native valve
Calcified valve tissue makes the annulus irregular, making it difficult to hold a prosthetic valve securely in the annulus
[0012] Furthermore, loading a valve onto a deployment system for minimally invasive procedures can be very challenging because of the nature of heart valve prostheses which need to be carefully loaded while at the same time must be packaged tightly in the deployment system. Compression of a heart valve prosthesis
[0013] Although transcatheter delivery methods have provided safer and less invasive methods for replacing defective natural heart valves, leakage between the implanted prosthetic heart valve and the surrounding natural tissue remains a recurring problem. question

Embodiment Construction

[0060] The accompanying drawings, which are incorporated in and form a part of this specification, also serve to explain the principles of the invention and to enable those skilled in the relevant art to make and use the invention. The figures are not drawn to scale.

[0061] Specific embodiments of the present invention are now described with reference to the drawings, wherein like reference numerals indicate identical or functionally similar elements. If used herein, the term "distal" or "distally" refers to a location or direction away from the heart, and the terms "proximal" and "proximally" refer to a location near the heart or towards the heart. 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 invention has been described in the context of the treatment of heart valves, the invention may also be used where it is useful for other valved endoluminal sites...

Abstract

The present invention concerns a prosthetic heart valve (10) for supporting or replacing a non- or malfunctioning native heart valve, the prosthetic heart valve (10) comprising an expandable generallytubular stent support (12), having an inner surface (16) and an outer surface (17), and comprising a valve element (20), having an outer surface (21), an inner surface (22), and comprising a plurality of sealing elements (30),wherein the sealing elements (30) are -spaced apart from one another -circumferentially attached to the outer surface (21) of the valve element (20) and form a lip-shaped element (31) radially protruding from the outer surface (21) of the valve element (20),wherein the valve element is mounted on the inner surface (16) of the stent support (12).

Description

technical field [0001] The present invention relates to an artificial heart valve for supporting or replacing a non-functional or malfunctioning natural heart valve. Background technique [0002] Heart valve replacement is necessary when the natural heart valve is damaged, malfunctioning, or non-functional. In the heart, the heart's valves keep blood flowing in one direction by opening and closing based on the pressure difference on either side. The mammalian heart consists of four chambers, two atria, which are the filling chambers, and two ventricles, which are the pumping chambers. In the mammalian heart, there are four heart valves that normally only allow blood to flow through the heart in one direction, whereby the opening or closing of the heart valves depends on the difference in blood pressure between the two sides. [0003] The four main valves in the heart are the left atrioventricular valve representing the mitral valve and the tricuspid valve, located between ...
