A flexible self-expandable stent comprises a plurality of radially cylindrical elastic units spaced at fixed intervals, a cylindrical cover fixing member which sheaths the cylindrical elastic units, and a reverse flow preventing valve. The reverse flow preventing valve is attached to the inner wall of the stent, for preventing food-stuffs or fluids from flowing from a downstream side to an upstream side. The flexible self-expandable stent exhibits improved flexibility so that when the stent is disposed in a curved lumina, it can flexibly correspond to the curvature of the lumina and prevent the reverse flow of foodstuffs or fluids by use of the reverse flow preventing valve.
