DetailsTesting to Improve the Durability of Artificial Heart Valves
Polymer leaflet heart valves can fail in long-term use due to tearing and calcification caused by high dynamic tensile and bending stresses on the material and oxidative reactions with blood. It was postulated that synthetic valve leaflets that mimic the natural valve leaflet structure fabricated from fiber-reinforced composite material will minimize leaflet stresses and decrease tears and perforations.

DetailsSimple Determination of the Linear Viscoelastic Region of a Polymer Using a Rheometer
Materials such as polymers exhibit viscoelastic behavior which is directly related to molecular structure and formulation differences. To accurately evaluate the relationships between molecular structure and viscoelastic behavior requires that experiments, such as rheological measurements, be conducted in regions where the viscoelastic properties observed are independent of imposed stress or strain levels. That is, experiments must be conducted in the linear viscoelastic region.
