摘要：
A vascular prosthesis is made by wetting a porous polyester fiber tubing with water until it gains close to maximum amount of weight, removing excess liquid from inside the tubing, repeatedly contacting the inside surface of the tubing with a solution of a biocompatible polymer in a water-immiscible solvent to adsorb some solution on the inside surface of the tubing, and removing excess solution, then removing solvent from the adsorbed solution to form a nonporous elastomer coating of the desired thickness on the inside surface of the tubing.
