Abstract
The invention relates to graftable polymers comprising biologically active agents and the use of such polymers in the manufacture of shaped articles, such as implantable medical devices and catheters. The graftable polymers are covalently grafted to a surface via one or more grafting moieties incorporated into the pharmaceutically-active graftable polymer. The coated articles of the invention can further comprise tie-coats, and the ratio of polymer:tie coat can be used to adjust the rate of drug elution.
