Patent ID: 7396541

Claim:
A medical device comprising as a coating a prodrug, the prodrug comprising a drug, heparin, and a polymer, wherein the heparin is linked to the polymer; wherein the drug is linked to the heparin or the polymer; and wherein the polymer is poly(L-lysine-co-ethylene glycol) (PLL-co-PEG), poly(L-lysine-co-hyaluronic acid) (PLL-co-HA), poly(L-lysine-co-phosphoryl choline) (PLL-co-PC), poly(L-lysine-co-PVP), poly(ethylimine-co-ethylene glycol) (PEI-co-PEG), poly(ethylimine-co-hyaluronic acid) (PEI-co-HA), poly(ethylimine-co-phosphoryl choline) (PEI-co-PC), poly(ethylimine-co-vinylpyrrolidone) (PEI-co-PVP), poly(L-lysine-g-ethylene glycol) (PLL-g-PEG), poly(L-lysine-g-hyaluronic acid) (PLL-g-HA), poly(L-lysine-g-phosphoryl choline) (PLL-g-PC), poly(L-lysine-g-PVP), poly(ethylimine-g-ethylene glycol) (PEI-g-PEG), poly(ethylimine-g-hyaluronic acid) (PEI-g-HA), poly(ethylimine-g-phosphoryl choline) (PEI-g-PC), and poly(ethylimine-g-vinylpyrrolidone) (PEI-g-PVP).
