Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," "upper," "lower," "far," "near," and similar expressi...

Abstract

The present invention relates to a heart valve, comprising a bracket and a flow blocking member, the bracket includes a leaflet bracket and a first skirt bracket, the flow blocking member covers the leaflet bracket, and the first skirt bracket is formed from the valve leaflet bracket. The leaflet support extends outward in the radial direction of the leaflet support, the leaflet support has an inflow end and an outflow end opposite to the inflow end, and the support also includes the leaflet support arranged on the leaflet support The elastic member between the outflow end and the first skirt support, the elastic member protrudes outward in the radial direction of the leaflet support, and / or the elastic member protrudes in the direction of the outflow end out. The above-mentioned heart valve can reduce the risk of paravalvular leak after implantation.

Description

technical field [0001] The invention relates to a medical device, in particular to a heart valve. Background technique [0002] Heart valve disease is a very common heart disease, among which valve damage caused by rheumatic fever is one of the most common causes. With the aging of the population, senile valvular disease and valvular disease caused by coronary heart disease and myocardial infarction are becoming more and more common. These valvular lesions not only endanger life safety and affect the quality of life, but also bring heavy burden and pressure to families and society. The human heart is divided into four chambers: the left atrium, the left ventricle, the right atrium, and the right ventricle. The two atria are connected to the two ventricles, and the two ventricles are connected to the two great arteries. Heart valves grow between the atrium and ventricle, between the ventricle and the aorta, and act as one-way valves to help blood flow in one direction. The...
