Claim:
A coating for an implantable medical device comprising a polymer of formula: wherein A is B is wherein the polymer is amino-terminated or carboxy-terminated; where R 1 and R 5 are optional and are independently selected from the group consisting of substituted, unsubstituted, hetero-, straight-chained, branched, cyclic, saturated and unsaturated aliphatic radicals; and substituted, unsubstituted, and hetero-aromatic radicals; R 3 is selected from the group consisting of substituted, unsubstituted, hetero-, straight-chained, branched, cyclic, saturated and unsaturated aliphatic radicals; and substituted, unsubstituted, and hetero-aromatic radicals; R 2 , R 4 and R 7 are independently selected from the group consisting of hydrogen; substituted, unsubstituted, hetero-, straight-chained, branched, cyclic, saturated and unsaturated aliphatic radicals; and substituted, unsubstituted, and hetero-aromatic radicals; R 6 is selected from the group consisting of substituted, unsubstituted, hetero-straight-chained and branched aliphatic radicals; L 1 is an optional linkage connecting A to B and, if present, comprises a disulfide, poly(ethylene glycol), methoxypoly(ethylene glycol), poly(ethylene oxide), poly(propylene glycol), poly(tetramethylene glycol), poly(ethylene oxide-co-propylene oxide), or a copolymer thereof; X is a biobeneficial agent selected from the group consisting of poly(alkylene glycols), methoxypoly(ethylene glycol), poly(N-vinyl pyrrolidone), poly(acrylamide methyl propane sulfonic acid), poly(styrene sulfonate), sulfonated dextran, polyphosphazenes, poly(orthoesters), poly(tyrosine carbonate), hyaluronic acid, heparin, a graft copolymer of poly(L-lysine) and poly(ethylene glycol), and salts, copolymers and combinations thereof; a free radical scavenger, a nitric oxide donor, rapamycin, tacrolimus, paclitaxel, docetaxel, estradiol, clobetasol, idoxifene, tazarotene, and salts and combinations thereof; antiproliferatives, antineoplastics, antimitotics, anti-inflammatories, antiplatelets, anticoagulants, antifibrins, antithrombins, antibiotics, antiallergics, antioxidants, and salts and combinations thereof; 40-O-(2-hydroxy)ethyl-rapamycin (everolimus), 40-O-(3-hydroxypropyl)-rapamycin, 40-O-[2-(2-hydroxy)ethoxy]ethyl-rapamycin, and salts and combinations thereof; L 2 is a linkage connecting X to the polymer; and n and m are independently integers not equal to 0.
