A synthetic vascular prosthesis comprises a hollow tubular base member having a multitude of continuous pores and formed of an elastomer material, and a hydrogel layer formed on the inner surface of the base member. The hydrogel layer is partly embedded in the inner portion of the base member at the pores, thereby permitting anchoring adhesion between the hydrogel layer and the base member. A method for manufacturing the synthetic vascular prosthesis is also disclosed, in which the formation of pores in the base member is effected by two separate steps and the hydrogel layer is formed after formation of an inner porous portion of the base member.

A synthetic vascular prosthesis having a compliance close to that of a natural blood vessel, consisting essentially of: a hollow tubular base member formed of an elastomer material and having formed throughout a wall thereof a multitude of continuous pores; and a hydrogel layer formed on the inner surface of said base member, the outer portion of said hydrogel layer being partially embedded in the inner portion of said base member at said pores to thereby achieve anchoring adhesion between said hydrogel layer and said base member, and said hydrogel layer having a smooth inner surface.
