More great features to improve AWT

  • Largest stroke volume AWT System on the market designed to meet DFM conditions with large valve prosthesis
  • Fully software-controlled system with active bypass valve control to meet ISO 5840 5% rule while avoiding excessive pressure and overloading of valves
  • Test modules standalone architecture with dedicated electronics, linear electromagnetic motors, automated by-pass control, and temperature measurement
  • Test system standalone architecture to eliminate neighboring test module disruptions during testing
  • Modular system to optimize parts and components interchangeability
  • True independent test modules with no fluid connections
  • Independent heaters and temperature sensors for each test module and corresponding test sample
  • Large test chamber design to fit a wide variety of valve sizes, geometry and supporting structures for TAVI, TMVR, TPVR, TTVR and surgical
  • No external pressure source or compressor required
  • Low hydrostatic load system design to increase lifespan of seals and bellows
  • Valve holder design for optimum chamber seal integrity
  • Integrated anti-vibration systems to minimize pressure signal disruptions and improve high speed video quality
  • Patent pending Inflow and outflow chamber annular compliance rings to optimize differential pressure waveforms
  • Vertical test sample configuration to minimize gravity asymmetric wear of valve leaflets
  • Adjustable intensity annular LED light for maximum high-speed imaging luminosity with minimal reflection impact
  • Customizable valve annulus ring to fit all valve geometries for TAVI, TMVR, TPVR, TTVR and surgical
  • Adjustable outflow pressure sensor height to accommodate different valve designs and conduits
  • Camera holder for repeatable high-speed camera positioning, increased image stability and reliability between inspection cycles
  • Embedded safety systems for fluid level, temperature change and pressure drop monitoring
  • Sliding test module mechanism for test sample inflow visualization, ease of setup and servicing
