The HiCycle is an accelerated wear tester (AWT) used to determine the durability or fatigue of replacement heart valves and other cardiac devices under physiological loading for R&D and regulatory submissions.
The HiCycle system uses an electromagnetic motor to drive 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 1,650 cycles/minute. Clear viewports allow imaging of the device during testing, and pressure ports allow monitoring of the dynamic pressures up and downstream of the device. Each test chamber is independent of the others to offer more testing flexibility.
When combined with the HiTest data acquisition system, operators are able to collect and analyze pressure data according to ISO-5840 standards through an intuitive user interface.

HiTest provides accurate pressure data and statistical analysis to ensure the tested devices are meeting ISO 5840 standards. The results highlight the percent of cycles and percent time per cycle the device is meeting or exceeding target pressure.
The ViVitro HiCycle Cart is specifically designed to make the ViVitro HiCycle system portable and raise it to a comfortable working height.
ViVitro offers a compact, battery-operated stroboscope to view devices while undergoing cycling. This rechargeable hand-held system allows for easy mobility to tester throughout the lab. The stroboscope also provides fast and accurate cycle per minute measurements to verify cycle rates.
This precision, handheld, digital pressure reference manometer allows for convenient calibration of pressure transducers.
