ABSTRACT:
Improved articles having reduced thrombogenicity when in contact with blood products containing albumin and methods of their preparation and use are provided. The articles comprise at the surface of blood contact a water insoluble polymeric substrate material having covalently attached thereon aliphatic extension of 12 to 22 carbon atoms. When exposed to blood, the aliphatic chain extensions provide a hydrophobic binding site for albumin. The articles when implemented with whole blood or blood products selectively enhance albumin affinity binding to the exclusion of other blood components, and subsequently minimize thrombus formation as well as other biocompatibility parameters, such as foreign body immune responses.
