Accelerated wear testing
for replacement heart valves

The ViVitro HiCycle Durability Tester is used to determine the durability of replacement heart valves and other cardiac devices under physiological loading for R&D and regulatory submissions.

With the Hitest Data Acquisition System, operators can monitor pressure and collect data according to ISO 5840 standards.

The HiCycle system uses an electrodynamic motor driving six pistons within fluid-filled, temperature-controlled chambers to move the device rather than the fluid. This results in higher energy efficiency and stable fluid flow. The devices can be cycled at accelerated rates up to 1,800 cycles/minute (30 Hz)”.

Clear viewports allow imaging of the device during testing, and pressure ports allow monitoring of the dynamic pressures upstream and downstream of the device.

Each test chamber is independent of the others to offer testing flexibility.

The ViVitro HiCycle Durability Tester is cited in numerous research studies throughout the world.   Visit our Citation Database for the current list of applications and articles.

HiCycle Close Up

ViVitro offers a family of quality data acquisition software products to aid in collection of data to meet ISO5840 requirements including ViVitest, Hitest and QCtest. The software is pre-installed on a laptop and tested with all hardware and A-D converters prior to shipment.

Each complete system is supplied with the following components to make up a functional system:
  • I/O Module – inputs/outputs signals from the software
  • Laptop
  • Connecting cables
  • Software (ViVitest, Hitest or QCtest)
  • AmPack Pressure Measuring System including transducers and amplifier
When coupled with the HiCycle or the Real-Time Wear Tester, Hitest provides the most powerful, userfriendly tool for durability testing. Operators are able to monitor pressure and collect data through an intuitive user interface. Hitest provides accurate pressure data and statistical analysis to ensure the tested devices are meeting ISO5840 standards. The results highlight the percent of cycles and percent time per cycle the device is meeting or exceeding target pressure.
