MP3
Pulse Duplicator
Clinically accurate hemodynamic heart valve testing
The MP3 is a pulse duplicator designed to generate physiological flows and pressures for testing
artificial heart valves while giving you full visibility of the prosthetic device.

MP3 Pulse Duplicator System Components
Designed to Ensure Regulatory Compliance with ISO and US FDA Regulations
ISO 5840 and the US FDA have clear regulations for the
hemodynamic evaluation of prosthetic heart valves. The MP3 is
compliant with ISO and FDA regulations and provides you with
real-time data to assess the device’s performance. The MP3 can be
used to evaluate the hemodynamic performance of transcatheter
and surgically-implanted aortic and mitral heart valves and LVADs.
Pulsatile fluid flow is measured ultrasonically and prosthetic heart
valves can be swapped out easily without completely draining the
system. System pressure can be measured at multiple points with
high natural-frequency transducers.

Versatility
The MP3’s optically transparent system components permit convenient visual, photographic, ultrasound or laser Doppler studies of the
valves.
Aortic and Peripheral Flow Loops
User-adjustable clamps on compliant vascular tubing allow you to independently adjust systolic and diastolic pressure and vascular
resistance.
Left Ventricle Chamber
The optically transparent left ventricle allows for an unobstructed view of the inlet and outlet sides of both mitral and aortic valves
simultaneously. Valves can be changed without emptying the MP3.
Motion Control System
The MP3’s drive system utilizes a programmable stepper motor that can break up each cycle into 121,600 steps, allowing the generation
of extremely accurate contour flow and pressure traces. The MP3 provides absolute control of dP/Dt, which is essential to the
elimination of mechanical valve cavitation problems.
MP3 Flow Loop
The MP3’s Flow Loop, controlled by the LabView®-based control software, vascular clamps and ultrasonic flow meter provide
outstanding control to the user, and the ability to vary performance parameters with an accuracy not previously available with pulse
duplicators.
M6 Test Sections
For users of Dynatek’s M6 Heart Valve Tester, test sections containing prosthetic valves may be transferred from the M6 to the Aortic
Assembly in the MP3, allowing you to evaluate hemodynamic parameters during an extended fatigue test.
