Patent ID: 8627708

Claim:
A device for simultaneous accelerated cyclic testing of a plurality of valved prosthetic devices comprising a pressurizable test chamber further comprising a fluid distribution chamber having a first manifold defining a first plurality of ports configured to receive and fluidicly couple with a first end of each of a respective plurality of sample holders and defining an aperture in a lower face in fluid communication with a pressure source; a fluid return chamber having a second manifold disposed opposite and spaced apart from the first manifold of the fluid distribution chamber and defining a second plurality of ports configured to receive and fluidicly couple with a second end of each of the respective plurality of sample holders; a fluid return conduit both structurally and fluidily connecting the fluid distribution chamber to the fluid return chamber; and a compliance chamber providing a volume for holding a gas or elastomeric material that compresses under a pressure placed upon fluid in the test chamber and; allows fluid in the test chamber to occupy a portion of the volume; a drive motor configured to operate cyclically, acyclically, or a combination of both; and a fluid displacement member connected with and driven by the drive motor to provide the pressure source that increases and decreases a pressure on fluid in the test chamber; whereby cyclic and acyclic fluid pressures are maintained throughout the test chamber.
