摘要（英）：

The invention discloses a prosthetic valve and a prosthetic valve device. The prosthetic valve comprises a sealing membrane and a valve leaflet, wherein the sealing membrane is of a barrel shape; an expanding opening is formed in each of two ends of the sealing membrane; an end opening of each expanding opening is of a tooth-shaped structure; the middle part of the sealing membrane is of a straight barrel shape; the inner diameter of each expanding opening is greater than the inner diameter of the middle part of the sealing membrane; the sealing membrane is formed by sewing at least three sealing membrane units; the valve leaflet is of an annular structure formed by sewing and connecting at least three valve leaflet units; the valve leaflet is arranged at the middle part of the sealing membrane. The prosthetic valve device comprises the prosthetic valve and a valve frame. The invention aims at providing the prosthetic valve for improving pulmonary regurgitation and the prosthetic valvedevice; the utilization safety and effectiveness are improved.
