Problems solved by technology

However, the implantation path of the valve stent has a large curvature. If the length of the compressed valve stent is too long, it will seriously affect the compliance of the delivery system during delivery and increase the difficulty of delivery.

Abstract

The valve stent comprises a stent body, the stent body comprises an inflow end, an outflow end and a narrowing part located between the inflow end and the outflow end, the narrowing part comprises a plurality of connecting rods connected with the inflow end and the outflow end, and the connecting rods are distributed in the circumferential direction of the stent body at intervals; the narrowing part has flexibility, the outflow end has a fixing function, the diameter of the tail end of the outflow end is not smaller than that of the head end of the inflow end, and the diameter of the narrowing part in the narrowest position in the radial direction of the support body is not larger than that of the head end of the inflow end. In this way, the bending capacity of the valve support can be improved.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to a valve support and a prosthetic valve assembly. Background technique [0002] At present, in order to facilitate the compression of the valve stent, the main structure of the stent is basically set to a rhombic mesh structure. After the stent with the rhombic mesh structure is compressed, the size is still large in both the length direction and the diameter direction. The implantation path of the valve stent has a relatively large curvature. If the length of the compressed valve stent is too long, it will seriously affect the compliance of the delivery system during the delivery process and increase the difficulty of delivery. SUMMARY OF THE INVENTION [0003] The main technical problem to be solved by the present invention is to provide a valve support and a prosthetic valve assembly, which can improve the bending ability of the valve support. [0004] In ord...
