Mitral HiCycle Durability Tester

Product Code: 27616

This enhanced version of the ViVitro HiCycle Durability Tester supports mitral valve durability testing for devices up to 55 mm in diameter. The Mitral HiCycle tests up to three devices simultaneously.

The Mitral HiCycle system uses the same electrodynamic motor as the original ViVitro HiCycle to drive three pistons within fluid-filled, temperature-controlled chambers moving the device rather than the fluid. The result is more stable fluid flow. Cycle rates are adjustable from 500 – 1,800 cpm (8.3 – 30 Hz). The Mitral HiCycle is available as a complete system or an upgrade kit can be purchased to convert existing HiCycles. The Mitral HiCycle is fully compatible with all the other ViVitro HiCycle components and accessories including:
  • Data Acquisition Software
  • HiCycle Cart
  • Bellows
  • Stroboscope
  • Manometer
