HDTi-6000 Heart Valve Pulse Duplicator Test System

In a revolutionary fashion, BDC Laboratories’ HDTi-6000 heart valve pulse duplicator achieves ISO 5840 performance assessment in a focused and efficient manner similar to our established HDT-500 system, with the added capability of integrated high speed video to facilitate real-time visualization of the heart valve under test. The HDTi-6000 can accommodate up to 5 high speed cameras, all simultaneously documenting multiple test article views with concurrent pressure and flow waveforms. After each heart valve test run, a variety of both waveform analyses and image analyses are available to characterize the heart valve’s performance and leaflet kinematics. Included with the many unique system features is the ability to playback video while synchronized to the pressure and flow waveforms to assess the heart valve leaflets at any particular point in the cardiac cycle.

The HDTi-6000 pulse duplicator can accommodate both surgically implanted and transcatheter valves while being configured as either as a left heart simulator or right heart simulator. Utilizing a novel linear clamp assembly with no need to drain the system between samples, the HDTi facilitates exchange of the test article in minutes and significantly increases productivity. BDC’s proven PD-1100 pulsatile pump is the fluid driving source for the HDTi-6000 pulse duplicator system yielding high repeatability, reproducibility and dynamic configurability.
