Abstract
A method to render a medical article antithrombogenic and/or anti-infective includes coextruding a base polymer with a hydrophilic laminating polymer having dispersed therein a quarternary salt complexing agent and steeping the extruded article in an aqueous solution of an antithrombogenic and/or anti-infective reagent whereby the reagent is absorbed along with water by the hydrophilic polymer and reacts with the complexing agent.
