Document Type and Number:
WIPO Patent Application WO/2023/284663
Kind Code:
A1
Abstract:
A valve stent, a valve prosthesis (100) and a valve prosthesis system. The valve stent comprises: a stent body (10), comprising an inner stent (12) and a plurality of first stents (112), wherein the plurality of first stents (112) are located on the outer periphery of the inner stent (12), and outflow ends of the plurality of first stents (112) are connected to the inner stent (12), and inflow ends are movable ends; and a connector (30), wherein the movable ends are movably connected to the connector (30), so that the first stents (112) and the connector (30) have a first positional relationship and a second positional relationship; when the first stents (112) and the connector (30) have the first positional relationship, the plurality of first stents (112) are in a retracted position, and when the first stents (112) and the connector (30) have the second positional relationship, the first stents (112) are in an expanded position. The valve stent will not excessively strain the first stents (112) thereof to break or shorten the fatigue life of the first stents (112).
