HiCycle Durability Tester

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.
