Abstract: A fatigue testing system (100) provides simultaneous cycle testing for a plurality of prosthetic devices under simulated physiological loading conditions. A plurality of sample holders (129) containing test samples (130) of prosthetic devices is positioned between a distribution chamber (126) and a return fluid chamber (136) to form an integrated test chamber (106). A reciprocating linear drive motor (105) operates a rolling bellows diaphragm (115) to cyclically pressurize fluid within the test chamber (106) and drive the pressurized fluid through the prosthetic devices (130) being tested. The test chamber (106) defines a return flow conduit (124) in fluid communication with each of the sample holders (129), the return fluid chamber (136), and the distribution chamber (126). Compliance chambers (135) and throttle valves (132) associated with each of the sample holders (129) regulate the pressure gradient and back pressure across the prosthetic devices (130) being tested.

Abstract: Prostheses are fatigue tested using an apparatus under simulated physiological loading conditions. A fluid housing defines an entrance chamber having fluid outflow ports and an exit chamber having opposing fluid inflow ports and a central flow conduit in communication with the entrance chamber and the exit chamber. A plurality of housing tubes into which prosthesis are deployed may extend between the fluid outflow and inflow ports. Alternatively, tubular prostheses may be connected directly between the inflow and outflow ports. A reciprocating linear drive pump having a flexible diaphragm is provided to cyclically pressurize fluid through a common closed loop within the fluid housing and drive the pressurized fluid through the prosthesis being tested. The test system is capable of rotation independent of the motor drive for accurate diameter measurements of all test samples at elevated frequencies.

Abstract: A directional flow valve in a cardiovascular prosthesis test system includes a regurgitant flow passage. Forward flow from a pump through the valve is unrestricted and allowed to pass freely through the directional flow valve. Regurgitant flow is allowed across the directional flow valve to reduce a negative pressure gradient across the prosthetic device. The volume of regurgitant flow is controllable by changing a size of the regurgitant flow pathway.
