CONNECTING STRUCTURE OF STENT AND VALVE LEAFLET AND INTERVENTIONAL VALVE-IN-VALVE AND INTERVENTIONAL AORTIC VALVE APPLYING CONNECTING STRUCTURE

摘要

A connecting structure of a stent and a valve leaflet is configured such that the stent is a metal mesh tube and the valve leaflets are three fan-shaped valve leaflets arranged on the inner side of the stent. Each of the three fan-shaped valve leaflets has a free edge, an arc-shaped bottom edge and valve leaflet junction connecting parts extending on two sides. Three connecting posts are uniformly distributed on the metal mesh tube. The junction connecting part of the fan-shaped valve leaflets includes a radial overturning connecting part and an axial overturning connecting part. The radial overturning connecting part of each fan-shaped valve leaflet penetrates through the connecting post from the inner side to the outer side then folds. After the inner side of the connecting post is folded, the axial overturning connecting part is connected and fixed to the connecting post through a suture.
