A coated vascular prosthesis and a method for its production

摘要

The vascular prosthesis has a body made from biostable and biocompatible polymeric material, and at least one surface portion thereof is coated with an impermeable layer based on a synthetic, biodegradable and biocompatible polymer having a coefficient of elasticity less than 10 MPa. Preferably, this polymer is a poly-(lactide-caprolactone) copolymer having an intrinsic viscosity Ä eta Ü, measured in chloroform at 25 DEG C, of less than 4 dl/g. The impermeable layer can be applied using coating or rolling techniques.
