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.

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.
