Abstract: A medical device for insertion or implantation in a body includes a polymer substrate and a layer of poly(vinyl pyrrolidone-alt-maleic anhydride) formed on a surface of the polymer substrate. Polymer chains of the poly(vinyl pyrrolidone-alt-maleic anhydride) are entangled with the polymer substrate.
