Valve prosthesis

Abstract

The application discloses a valve prosthesis, comprising an inflow end, an outflow end and a main body part, two ends of the main body part are connected with the inflow end and the outflow end respectively, the maximum circumference of the main body part is greater than the maximum circumference of the inflow end or the outflow end; further comprising a valve leaflet assembly, the valve leaflet assembly is connected with the inner wall of the main body part, the maximum circumference of the valve leaflet assembly is greater than the maximum circumference of the inflow end or the outflow end. Thus, by the maximum circumference of the main body part being greater than the maximum circumference of the inflow end or the outflow end, the valve leaflet assembly is connected with the inner wall of the main body part, the maximum circumference of the valve leaflet assembly is greater than the maximum circumference of the outflow end or the outflow end, so that the opening area of the valve leaflet assembly is increased, so as to facilitate the blood flow through the valve leaflet assembly and promote the blood circulation.
