Embodiment Construction

[0036] 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.

[0037] 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 invention relates to a heart valve. The heart valve comprises a stent; the stent comprises a valve leaflet stent and a skirt edge stent; the valve leaflet stent and the skirt edge stent are prepared through one time moulding; the valve leaflet stent is provided with a first end and a second end opposite to the first end; the skirt edge stent is designed to stretch outward along the radial direction of the valve leaflet stent; the end of the skirt edge stent close to one end of the valve leaflet stent, and the first end are arranged at an interval, and the distance from the end of the skirtedge stent to the first end is 1 / 2 to 1 / 4 of the radial direction length of the valve leaflet stent. The heart valve is capable of avoiding ventricular outflow tract stenosis caused by 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...
