Bioinspired polymeric heart valves derived from polyurethane and natural cellulose fibers

In this work, bioinspired anisotropic polymeric heart valves were fabricated using composite materials from polyurethane (PU) and natural cellulose fiber bundles. The hydrodynamic performance of the polymeric valve was evaluated by the ViVitro Pulse Duplicator system. Our results demonstrate the potential application of bioinspired anisotropic CPU composites as polymeric heart valves.
