Nonwoven cloth has been considered to beasuitable material to be used as vascular substitutes, with its unique velour-like surface structure. Animal experiment showed that the thin and smooth layer of pseudointima on the luminal surface of the prosthesis has been always seen, whether the prosthesis has high porosity or not. So we have developed a 3-layered laminated vascular prosthesis made of a new nonwoven cloth which has no porosity.
