Abstract

The invention discloses a valve stent and a prosthetic valve assembly. The valve stent comprises an inner stent body and an outer stent body which are connected with each other. The inner support comprises at least two first extending parts, and the first extending parts face the outer support and form a first angle with the inner support. The outer support comprises at least two second extending parts, and the second extending parts face the inner support and form a second angle with the outer support. Each first extension part is correspondingly connected with the corresponding second extension part; at least one of the first angle and the second angle is not a right angle. In this way, the anchoring effect of the valve stent on the native heart tissue can be enhanced.

Description

technical field [0001] The present application relates to the technical field of medical devices, and in particular, to a valve stent and a prosthetic valve assembly. Background technique [0002] Heart valve disease is a very common heart disease, such as valve damage that may be caused by rheumatic fever. 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 valve diseases not only endanger life safety and affect the quality of life, but also bring serious burden and pressure to the family and society. [0003] Currently, a valve prosthesis can be implanted into a diseased heart valve through a heart valve replacement, that is, an interventional, minimally invasive method to replace the patient's original diseased heart valve. However, due to the high pressure of blood flow between the atrium and the ventricle, the valve stent is prone to displacem...
