Abstract

The invention provides a heart valve which comprises a valve support, a flow choking piece and a valve leaflet. The valve support comprises a valve leaflet support and a skirt support. The flow choking piece covers the valve leaflet support. The valve leaflet is arranged in the valve leaflet support. The skirt support extends outwards from the valve leaflet support in the radial direction of the valve leaflet support. The heart valve further comprises a balloon surrounding the outer wall of the valve leaflet support. The heart valve can reduce central reflux to a large extent.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a heart valve. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] 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 gro...
