Abstract:
A valve stent, a valve prosthesis, and a valve prosthesis system. The valve stent comprises, along an axial direction of the valve stent, an inflow channel section (10), an outflow channel section (20), and a hanging lug section (30) sequentially arranged. The outflow channel section (20) is provided with valve leaflet connecting parts (21). The valve leaflet connecting parts (21) are used for connecting valve leaflets (1). The hanging lug section (30) at least comprises a pair of hanging lugs (31) arranged on two sides along an axial direction of the valve leaflet connecting parts (21), or the hanging lug section (30) at least comprises a hanging lug (31) arranged at a position extending along the axial direction where the valve leaflet connecting parts (21) are located. In this way, the hanging lug section (30) can ensure uniform stress of the valve leaflet connecting parts (21), so as to improve the uniform stress of the whole valve stent, thereby improving the uniformity of the valve stent for being pressed into a delivery system and the accuracy during release.
