Abstract
Polymeric surfaces of medical devices or components of medical devices are provided that have enhanced biocompatibility properties. The polymeric surface presents an anti-thrombogenic, fibrinolytic or thrombolytic interface with body fluids such as blood during implant ation or medical procedures. The biocompatibility enhancing agent is secured to the polymeric substrate by a spacer molecule which is covalently bound to the polymeric substrate which had been subjected to radiofrequency plasma treatment with a water vapor medium.
