PROBLEM TO BE SOLVED: To provide an artificial valve with which position shifts and blood flow leaks can be suppressed or prevented.SOLUTION: An artificial valve includes a valve body and a tubular artificial valve support body for supporting the valve body, and is placed percutaneously. The artificial valve includes: protrusions which have an outer peripheral surface coming into contact with in vivo tissue and protrudes from the surface on both ends of the artificial valve support body to the outside in a radiation direction; and a cusp housing part which allows a cusp to penetrate between the protrusions on both ends. The artificial valve can suppress or prevent position shifts and blood flow leaks. |
