The purpose of this test is to determine 

the EOA and regurgitant fraction of the 

test valve in simulated physiological and 

pathological hydrodynamic conditions

(Beat rate,Systolic duration,Cardiac 

output,Mean arterial pressure). 

The purpose of this test is to determine the forward flow resistance performance (pressure difference across the test valve ,the EOA of the test valve ) in simulated quasi-steady fluid of ventricular ejection peak (flow rate). 

The purpose of this test is to determine the leakage volume flow rate of closed heart valves as a function of back pressure. 

The purpose of this test is to demonstrate in vitro durability of test valve under appropriate loads while simulating device function in an appropriate fluid environment to a specified number of cycles.

The purpose of this test is to identify potential durability-related failure modes of valve by testing devices under more severe loading conditions than experienced during AWT.

The purpose of this test is to identify frequency-dependent failure modes under better simulated physiological loading conditions(e.g.waveform, load duration)when compared to AWT in an in vitro environment.

The purpose of this test is to demonstr

ate in vitro durability of structural com

ponent of test valve under appropriate 

loads while simulating its function 

in an appropriate fluid environment to 

a specified number of cycles.

The purpose of this test is to evaluate the in vitro durability of vascular stents by applying pulsating loads to keep them within a pressure scope or expansion scope similar to that of the in vivo environment.

The purpose of this test is to evaluate the long-term structural integrity of stents under periodic torsional loads suitable for device design and intended clinical use.

The purpose of this test is to evaluate the long-term structural integrity of stents under periodic bending loads suitable for device design and intended clinical use.

The purpose of this test is to evaluate the long-term structural integrity of stents under periodic axial loads suitable for device design and intended clinical use.
