Instant Wave-Free Ratio — iFR

The leading hyperemia-free physiologic index for measuring pressure in diagnostic and interventional procedures, which can improve outcomes, save time, and reduce patient discomfort^(1-3). iFR is measured using the world's first solid core pressure guide wire, OmniWire, with values co-registered* directly on the angiogram. This advanced physiologic guidance helps identify precisely which parts of a vessel are causing ischemia, to help determine treatment strategy.
