Pulse Duplicator


The world’s most
widely-used heart model
  • Flow and pressure readings can be collected and analyzed in real-time, meeting ISO 5840 requirements
  • Controls pulsatile fluid flows to simulate various cardiac flow conditions including arrhythmia, normal, hypo and hypertensive states at an assortment of cardiac outputs and beat rates
  • Transducer sites allow measurement of wall pressures in the atrium, ventricle, and aortic outflow tract
  • Flow can be measured directly at the aortic or mitral sites
  • Simulates cardiovascular peripheral resistance and compliance
  • Thin acrylic windows permit echo imaging, Doppler flow measurements, and PIV for interrogation of flow field regions
  • Allows hydrodynamic testing of heart valve replacements in order to assess mechanical and hemodynamic performance
  • Ventricle membrane to replicate the natural chamber flow
  • Accessories are available for testing other implantable cardiac devices including Occluder and Closure Devices.
Testing Capabilities and Applications
  • Surgical valves (Mechanical and Biological)
  • Stentless valves
  • Structural heart and peripheral vascular devices
  • Occluder and Closure Devices (with customization)
  • Evaluate LVAD or other assist devices (with customization)

Max 10W
Heat Bath*
Heater Capacity 1.2kW
Flow Meter*
*We recommend connecting the Flow Meter to a different circuit than the Heat Bath. The Flow Meter is a sensitive measurement instrument and the large Heat Bath current draw can cause minor disturbances in the flow measurements when the heater switches on.

It really is like an industry standard.  I love the machine.
