Abstract
Disclosed are hybrid coatings for implantable medical devices. Such coatings include a first layer of an aqueous dispersion or emulsion of an organic acid functional group containing polymer, a crosslinker and a therapeutic agent dispersed therein. The coating also includes a second layer of an aqueous solution or dispersion of an organic acid functional group-containing bio-active agent. The hybrid coatings are especially suited for preventing restenosis of endoprostheses by the combined action of the therapeutic agent and the bio-active agent. Methods of making and using devices coated with such compositions are also provided.
