Assignee:	Advanced Cardiovascular Systems, Inc. (Santa Clara, CA)
Application Number:	11/638,780
Patent Claims:	1. A coating on an implantable device, the coating comprising a phosphoryl choline polymer, wherein about 50 wt % or more of the coating can absorb or dissolve within 24 hours after implantation, wherein the phosphoryl choline polymer comprises at least one phosphoryl choline moiety and at least one moiety derived from a biocompatible polymer, wherein the biocompatible polymer comprises poly(ester amide), poly(lactic acid), poly(glycolic acid), poly(caprolactone), poly(dioxanone), or poly(ester amide-2,2,6,6-tetramethyl-1-piperidinyloxy) (PEA-TEMPO), wherein phosphoryl choline polymer comprises a fragment having the formula of ##STR00002## wherein R is selected from the group consisting of methyl, ethyl, propyl, and butyl group, where n and in are the fractional percentage of monomers in phosphoryl choline polymer and independently range from about 0.01 to about 0.99, wherein the fragment of Formula X has a Mw of 10,000 Daltons or below. 2. The coating of claim 1, wherein the fragment of Formula X has a Mw of 5000 Daltons or below. 3. The coating of claim 1, wherein n and m are each about 0.5. 4. The coating of claim 1, wherein the phosphoryl choline polymer is random or block copolymer. 5. The coating of claim 1, further comprising a bioactive agent. 6. The coating of claim 5, wherein the bioactive agent is selected from the group consisting of paclitaxel, docetaxel, estradiol, nitric oxide donors, super oxide dismutases, 4 amino-2,2,6,6-tetramethyl piperidine-1-oxyl (4-amino-TEMPO), tacrolimus, dexamethasone, rapamycin, 40-O-(2-hydroxy)ethyl-rapamycin (everolimus), 40-O-(3-hydroxy)propyl-rapamycin, 40-O-[2-(2-hydroxy)ethoxy]ethyl-rapamycin, and 40-O-tetrazole-rapamycin, 40-epi-(N1-tetrazolyl)-rapamycin (ABT-578), pimecrolimus, imatinib mesylate, midostaurin, clobetasol, mometasone, CD-34 antibody, abciximab (REOPRO), progenitor cell capturing antibody, prodrugs thereof, or a combination thereof. 7. The coating of claim 1, wherein the implantable device is a stent. 8. A method of treating a disorder in a human being by implanting in the human being an implantable device comprising the coating of claim 1, wherein the disorder is selected from the group consisting of atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, and combinations thereof.
