Schematic of the NO releasing coating (A), control coating (B) and assembled ECC loop (C). The base coat of 100% PVC limits NO diffusion into the Tygon™ tubing. The NO releasing ECC consists of an active coat of plasticized PVC doped with a lipophilic DBHD/N2O2 and the PLGA additive. The control ECC consists of plasticized PVC doped with the PLGA additive. The top coat of plasticized PVC over the active/control coats provides a smooth surface and neutralizes the charge on the surface of the assembled ECC.
