摘要

The present invention provides a valved stent that can provide a valve function without blocking a branch blood vessel, and also can provide a valve function with minimum covering of blood vessel tissue in a stent indwelling section. Specifically, a cylindrical stent body 4 is provided. A leaflet 5 that can open/close a blood vessel 2 in a blood flow direction is provided. The leaflet 5 is composed of connective tissue and protrudes radially inward from the stent body 4. An inside and an outside of the stent body 4 radially communicate with each other. The stent does not block a branch blood vessel 8. An area of the blood vessel covered with the stent is reduced.
