Patent ID: 7732535

Claim:
A coating for an implantable medical device comprising a polymer having the chemical formula: [—CH 2 CH 2 —/—CH 2 CH(R)—/—CH 2 CH(OH)—] p ( m,n,o ) wherein: R is selected from a group consisting of alkyl-O—, alkylsulfonyl-O—, NHR 1 , phenyl, alkylphenyl, trifluoromethyl, perfluoroalkyl, R 1 HNC(O)—, R 1 HNC(O)O— and a macromolecule, wherein: the alkyl group of the alkyl-O—, or alkylsulfonyl-O— is unsubstituted, partially fluorinated or fully fluorinated; R 1 is selected from the group consisting of monomethylated poly(ethylene glycol), poly(propylene glycol), poly(vinylpyrrolidone), poly(acrylamide), poly(2-hydroxyethylmethacrylate), a phospholipid, heparin, low molecular weight heparin, a heparinoid, hyaluronic acid and albumin; the macromolecule is selected from the group consisting of poly(ethylene glycol), poly(propylene glycol), poly(vinylpyrrolidone), poly(acrylamide), poly(2-hydroxyethylmethacrylate), a phospholipid, heparin, low molecular weight heparin, a heparinoid, hyaluronic acid, albumin and a polysiloxane; m is the mol percent CH 2 CH 2 — in the polymer and is from about 20 to about 80; n is the mol percent CH 2 CH(R)— in the polymer and is from about 1 to about 40; o is the mol percent CH 2 CH(OH)— in the polymer and is (100−(m+n)); and, p is from about 20,000 Da to about 500,000 Da.
