Problems solved by technology

However, this kind of valve has a large volume and needs to be implanted through a large delivery system, which increases the surgical trauma. At the same time, the opening area of ​​the valve is small, which also has a certain impact on hemodynamics.

Abstract

The invention relates to an interventional mitral valve stent. The interventional mitral valve stent comprises an upper valve part and a valve leaflet hanging part; the upper valve part is connected above the valve leaflet hanging part; and the rigidity of the upper valve part is less than that of the valve leaflet hanging part. According to the invention, the rigidity of the upper valve part on the valve stent is less than that of the valve leaflet hanging part; therefore, the relatively soft upper valve part can be fully attached to a human body valve orifice; natural shaping is carried outaccording to the shape of the human body valve orifice; therefore, backflow can be effectively reduced; postoperative endothelialization can be effectively accelerated; the interventional valve can stably work in vivo; meanwhile, the valve leaflet hanging part has relatively high rigidity; the reliability of fixing the valve leaflet can be improved; normal work of the interventional valve is guaranteed; and the service life of the interventional valve is prolonged.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to an interventional mitral valve stent. Background technique [0002] Since the valve orifice of the human mitral valve is generally in the shape of a saddle, its front, rear, left, and right are not on the same plane, although these factors have been fully considered in the design process of the interventional mitral valve, so that the upper part of the interventional valve can be aligned with the human mitral valve. The valve mouth is fitted as much as possible to reduce paravalvular leakage and endothelialize as soon as possible so that the interventional valve can be integrated with the human body. However, due to the great individual differences in the human body, it is difficult for a stereotyped product to adapt to each individual shape, which may cause paravalvular leakage, which cannot be endothelialized or the valve cannot be integrated with the human bo...
