NO releasing (NORel) fabrication and top coat of argatroban-immobilized E2As polyurethane. Schematic of polymer containing a lipophilic diazeniumdiolated dibutylhexanediamine (DBHD/N2O2) and incorporated at 25 wt % into E2As polymer was coated as active layer on inner surface of PVC tubing. This was coated as an active layer on PVC tubing. The NORel coating was then top coated with the argatroban-immobilized E2As bulk polymer as a single layer (structure of argatroban/HMDI/E2As shown below arrow). The argatroban/PEG-DI/E2As bulk polymer is similar in structure as the shown HMDI-linked polymer except the C6 portion of linker is replaced by a diisocyanate linker that contains a 36 mer repeat unit of PEG.
