ABSTRACT:
A method and device for testing artificial or natural venous valves. The device comprises (a) a fixture for mounting a sample valve on a liquid flow path, (b) a muscle pump component and/or (o) respiratory pump component and/or (d) capacitance reservoir component and/or (e) vertical hydrostatic column component, all of the components being fluidly connected to the flow path to mimic the muscle pump, respiratory pump, capacitance and hydrostatic impedance effects of actual in situ venous circulation in the mammalian body. The invention includes methods of testing venous valves by mimicking known hemodynamic flow conditions within a mammalian body.
