Heart valves bodies and leaflets can experience axial loading due to pressures and motion. The fatigue resistance of the valve body and/or leaflet to repeated axial loading must be tested to ensure long term efficacy. The fixture shown was designed to apply an axial compressive fatigue load to a valve body. This particular fixture is designed for 15 specimen stationsand can be used in a 37°C saline bath.
Contact us with your specific test requirements and we will provide an estimate for creating the compression testing fixture and test you are looking for.
