Ex Vivo Simulator

Product Codes: 29348: Ex Vivo System Bundle / 10647: SuperPump System / 25654: Compliance Assembly 30146: Accessories / 30543: Tray Assembly

The Ex Vivo Simulator uses a ViVitro Labs SuperPump pulsatile pump to generate physiological flows in an excised heart for bench top testing. The system can model either the left or right heart, or two systems can be combined to generate a four chamber model.

Features:
  • The Ex Vivo beating heart combines clinical anatomical similarity with controllable physiological flow and pressure signatures for bench top testing. This results in repeatability and ease of use, and anatomical and functional performance previously only found in animal models.
  • Access sites at the arteries, atrium and apex allow for the insertion of catheters and other devices. Optional pressure transducers and data acquisition system acquire the arterial, ventricular and atrial pressures and a flow meter measures the cardiac output of the simulator.
  • Investigate valve movement with an endoscope or ultrasound. Pathological states such as low ejection fractions and high beat rates can be simulated with the heart via the SuperPump pulsatile pump. Degenerative and functional mitral regurgitation can be simulated by severing the mitral chords and pressurizing the left ventricle, respectively.

Heat Exchanger

Heat Exchanger Product Code: HE9991

The ViVitro Heat Exchanger allows heating of test fluid with minimal interference of the fluid flow.

  • An isolated inflow and outflow metal heat conducting channel transfers heat to the solution
  • Maintains testing solution to desired temperature ± 0.5°C

Interchangeable Components

SuperPump Pulsatile Pump

The most widely used computer-controlled pump for cardiac flows. The ViVitro SuperPump pulsatile pump that powers the Endovascular Simulator is also the foundation for ViVitro’s Pulse Duplicator and Real Time Wear Tester. The SuperPump pulsatile pump can be operated independently with any type of cardiac flow loop. The SuperPump pulsatile pump provides pulsatile flow from 3 to 200 Beats per Minute and up to 15 Litres per Minute output. A Pump Head facilitates circulatory flow using two valves.
