Patent ID: 8597673

Claim:
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 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.
