Key result
A polyvinyl alcohol hydrogel prepared with 10% PVA, cycle 3, and 75% initial strain successfully matched the oriented stress-strain properties of porcine aorta.
A novel technique applying controlled strain during thermal cycling allows the creation of anisotropic PVA hydrogels that mimic the mechanical properties of cardiovascular tissues like the aorta.

May guide vascular biomaterial design; leaves open in vivo durability and human translation.
Millon et al. (2006) studied Cardiovascular applications. Anisotropic polyvinyl alcohol (PVA) hydrogel vs. Porcine aorta was evaluated on Oriented stress-strain properties. A polyvinyl alcohol hydrogel prepared with 10% PVA, cycle 3, and 75% initial strain successfully matched the oriented stress-strain properties of porcine aorta.
