Implantable vascular devices and implantable cardiovascular devices suitable for contacting a patient's blood or bodily fluids include a polymer substrate that is at least partly coated with a diamond-like carbon coating. The diamond-like carbon coated polymer substrate can be flexible or rigid. Preferred medical devices include heart valve prostheses with leaflets or orifice rings formed from diamond-like carbon coated polymer materials. Preferred approaches for the deposition of the diamond-like carbon coating are performed at low pressures and include ion beam assisted deposition. |
