Compressive Force Characterization of Inferior Vena Cava Filters

Mechanical testing techniques are commonly used to quantify the compression characteristics of such devices. The goal of these tests is to determine a relationship between the compressive displacement and the resulting force on the devices. A precise and accurate assessment of force against displacement can be performed by using the ElectroForce® 3200 Series III test instrument.

Testing 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.
