Abstract
This present invention relates to drug eluting polymers, including novel biodegradable drug eluting polymers, which are added to the surface of a medical device to treat device associated complications and to deliver drug locally around the device. Methods of making polymers, for example, drug-eluting polymers, polymer compositions, and materials used therewith also are provided. The drug eluting polymers are obtained from the polymerization of macromonomers made of a connecting moiety, a biodegradable moiety and a cross-linkable moiety that are liquids at a temperature of 10° C. to 40° C.
