Continuous rod-like molding having a FRP core and an outer skin of thermoplastic resin is shaped by introducing the molding into a passage of a heated die, the passage having a diameter slightly smaller at an exit thereof than an initial diameter of the molding, plasticizing the thermoplastic resin by passing the molding through the passage, thereby removing a part of the outer skin, and solidifying the thermoplastic resin, thereby obtaining a product having a diameter equal to the diameter of the exit of the passage.

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.
