Patent ID: 7226586

Claim:
A highly cross-linked, extremely hydrophobic nitric oxide releasing biocompatible polymer wherein said biocompatible polymer is a polyamine derivatized form of polydivinylbenzene having the general formula: wherein R 1 through R 4 are the same or different and may be H, phenyl, benzyl, vinylbenzene, divinylbenzene, un-substituted and substituted alkyl and substituted and un-substituted aryl groups, X 1-4 are same or different and may be H, a halogen, an un-substituted or substituted alkyl and substituted or unsubstituted aryl groups providing that the resulting polymeric backbone remains hydrophobic and wherein at least one of R 5 and R 6 is: wherein R 7 is a hydrophobic polymer backbone, R 8 may be nothing or a C 1-12 unbranched or branched alkyl group and R 9-13 may be H or N 2 O 2 − providing that at least one of R 9-13 is N 2 O 2 − ; and wherein said biocompatible polymer does not swell upon immersion in an aqueous solution.
