ABSTRACT:
A method and device for testing artificial or natural venous valves. The device comprises chamber (10) a sample for mounting a test valve (V) on a liquid flow path and a muscle pump component (16) and/or respiratory pump component (50) and/or capacitance reservoir (58) and/or vertical hydrostatic column component (102) fluidly connected to the flow path to mimic the muscle pump, respiratory pump, capacitance and hydrostatic impedance effects on venous circulation in the mammalian body. Included in the invention are methods of testing venous valves by mimicking known hemodynamic flow conditions within a mammalian body.
