Meet with ViVitro Labs at VEITH 50th Annual Symposium

November 6th, 2023

Veith New York 2023

Meet with ViVitro Labs at VEITH 50th Annual Symposium. Connect with Douglas Bigrigg, Business Development Manager of Equipment, Testing Services, and Test Applications –  Americas, in New York City, on November 13 – 17, 2023.

Now in its 50th year, VEITH symposium provides vascular surgeons, interventional radiologists, interventional cardiologists and other vascular specialists with a unique and exciting format to learn the most current information about what is new and important in the treatment of vascular disease.

Meet with Douglas Bigrigg, ViVitro Labs Business Development Manager of Equipment, Testing Services, and Test Applications –  Americas, at VEITH 50th Annual Symposium to discuss your cardiovascular device testing and engineering challenges.

 


ViVitro Heart Valve Prosthesis AWT System

ViVitro Labs Heart Valve Durability Tester with ADC™ technology

With Dual Control Technology (DCT)™ for constant leaflet closing velocities during the entire AWT cycling period

ViVitro’s AWT System with DCT™ uses two separate position feedback sensors and algorithms to maintain constant leaflet closing velocities across the entire AWT cycling period. Piston displacement and bypass valve are controlled independently to meet differential pressure requirements while preserving initial leaflet closing velocities.

  • Patent pending Dual Control Technology to maintain constant leaflet closing velocities during Accelerated Wear Testing (AWT) and Dynamic Failure Mode (DFM)
  • Maximum versatility with pre-wired controller unit and data acquisition system for easy PnP upgrade of up to 6 test modules
  • True standalone architecture with independent test modules to avoid disruptions to adjacent on-going test
  • Transparent test chambers with inflow, outflow, and lateral visibility for optimum test samples visualization during testing
  • Patent pending flow loop system to operate system under low hydrostatic pressure conditions and avoid the need for an external pressure source

 


ViVitro Pulse Duplicator system

 

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.
