Patent ID: 8821906

Claim:
A biocompatible polymer composition comprising a bismuth complex, a polyurethane film forming polymer, and a polylactone-polydimethyl siloxane-polylactone triblock copolymer with mono, bi, or multiple end-groups reactive with the polyurethane polymer, wherein the bismuth complex is incorporated into the composition at 0.03% to 0.5% by weight bismuth and is at least one of ammonium bismuth citrate, bismuth(III)oxide, bismuth(III)gallate hydrate, bismuth citrate, bismuth(III)oxychloride, bismuth(III)tetramethylheptanedionate, bismuth(III)hexafluoracetonate, bismuth(III)subsalicylate, triphenylbismuth, bismuth(III)ciprofloxacin, bismuth(III)chloride, triphenylbismuth dichloride, triphenylbismuth carbonate, triphenylbismuth di hydroxide, triphenylbismuth dinitrate, triphenylbismuth disalicylate, triphenylbismuthine, triphenylbismuth bis(2-chloroacetate), triphenylbismuth bis(4-aminobenzoate), bis(acetato-O)triphenylbismuth, dibromotriphenylbismuth, or difluorotriphenylbismuth.
