Abstract

A method of fabricating a prosthesis material, particularly vascular, made of a synthetic polymer and having improved smoothness, desirable pore characteristics along with more uniform dimensions. The method involves fabrication by precipitation of a synthetic polymer from a solution onto the inside wall of a tube or other cylindrical conduit, the precipitation being carried out in the presence of a precipitating solution which provides a liquid-liquid interface for the formation of the inner surface of the synthetic material.
