An artificial vessel having an excellent patency, wherein the vessel wall is made of an elastomer having a porous structure and the contact surface with blood has pores with a mean diameter of from 1 to 100 mu m and holes with a mean diameter of from 0.01 to 10 mu m. The artificial vessel may also be reinforced with tubular material made of fiber or with heat-set tubular material made of fiber so that the vessel has a stress-strain curve approximate to that of a vital vessel or the vessel can be subjected to sterilization by boiling or by high-pressure steam. The artificial vessel has the porosity, contact surface with blood suited for encapsulation, and an excellent patency as well as a compliance approximate to that of a vital vessel. |
