Duplicator

The world’s most
widely-used heart model

The ViVitro Pulse Duplicator system is the world’s most widely cited and most used in-vitro cardiovascular hydrodynamic testing system.

The ViVitro Pulse Duplicator simulates the function of the heart (left or right) by generating pulsatile flow through prosthetic heart valves placed in the Model Heart (Left or Right). Powered by the ViVitro SuperPump pulsatile pump, it is composed of the ViVitro Model Heart (Left or Right), SuperPump pulsatile pump, Flow Measuring System and ViViTest data acquisition system. The components work together to assess the performance of prosthetic heart valves under simulated cardiac conditions. The ViVitro Pulse Duplicator System is used by the US Food and Drug Administration and is recognised and used by regulatory bodies worldwide including TÜV, BSI and Chinese CFDA.

The Pulse Duplicator System assesses the performance of cardiovascular devices and prosthetic heart valves under simulated cardiac conditions. It simulates physiological or other complex flow variations while allowing the user to vary the peripheral resistance and compliance of the system. Pressure ports and flow measuring locations allow for data to be collected from aortic or mitral sites. Transparent viewpoints allow multiple viewing angles of the valve including inflow and outflow.

Combined with the ViVitest software control system, it quickly, easily and reliably collects and analyzes physiological flow and pressure data. The ViVitest software also allows the user to easily modify and customize waveforms.

The ViVitro Pulse Duplicator System is cited in numerous research studies throughout the world. Visit our Citation Database for the current list of applications and articles.
