1. A method for reducing the thrombogenicity of a substrate, comprising the steps of:

  • a. plasma polymerizing polar organic monomers onto the surface of the substrate to provide a plasma polymer film on the surface of the substrate;

    b. attaching an a anticoagulant, so that it is bound, directly or indirectly, to the plasma polymer film to provide a substrate having reduced thrombogenicity.
