Abstract
Articles comprised of bioactive agents coupled to or repelled by a graft polymer (made, for example, from monomers such as N-(3-aminopropyl) methacrylamide hydrochloride (APMA), 2-acrylamido-2-methylpropane sulfonic acid (AMPS), acrylamide (AAm), and acrylic acid (AA)) which is in turn bonded to a polymeric substrate surface. The articles are useful as thromboresistant and/or antimicrobial medical devices.
