摘要 |
An artificial mitral valve 10 is provided with a ring 12 divided along the circumferential direction into two; an anterior cusp-side region 44 and a posterior cusp-side region 45 and an artificial valve leaflet 11 connected along an outer edge of the ring 12. The artificial valve leaflet 11 is made up of a symmetric anterior cusp forming member 14 connected to the anterior cusp-side region 44 and a symmetric posterior cusp forming member 15 connected to the posterior cusp-side region 45. The anterior cusp forming member 14 is provided with an upper edge 17 joined to the ring 12 and a lower edge 22 connected to the upper edge 17 and forming a bifurcated portion 20. The upper edge 17 is made up of a pair of right and left inclined edges 24 inclined inward and upward from the right and left sides and a curved edge 25 interposed between the inclined edges 24 and curve-shaped along a reference region 48 of the anterior cusp-side region 44. The posterior cusp forming member 15 is provided with an upper edge 31 joined to the ring 12 and a lower edge 37 connected to the upper edge 31 and forming a bifurcated portion 35. |
