SUSTAINED NITRIC OXIDE RELEASE COATING USING DIAZENIUMDIOLATE-DOPED POLYMER MATRIX WITH ESTER CAPPED POLY(LACTIC-CO-GLYCOLIC ACID) ADDITIVE

摘要

A polymeric composition includes a polymer matrix having a lipophilic discrete nitric oxide adduct and/or a polymeric nitric oxide adduct associated therewith, by covalent attachment to the polymer matrix and/or by dispersion within the polymer matrix, with the discrete nitric oxide adduct and/or the polymeric nitric oxide adduct being capable of releasing nitric oxide (NO). The polymeric composition further includes an ester capped poly(lactide-co-glycolide) (PLGA) additive to at least one of increase, prolong, and control NO release rates from the lipophilic discrete nitric oxide adduct and/or the polymeric nitric oxide adduct.
