When integrated into lab procedures, measurement of fractional flow reserve (FFR) has been shown to reduce the incidence of adverse events in patients being treated for complex coronary artery disease. Compared to angiography alone, FFR:
- Allows more accurate identification of hemodynamically relevant stenoses, reducing rates of death, myocardial infarction and repeat revascularization2
- Improves outcomes and patient quality of life
- Lowers procedure-related costs
- Does not increase procedure time
- Decreases the amount of contrast agent used
Precise measurement of intravascular pressure relies on the market-leading wire that combines exceptional maneuverability–even in tortuous vessels–and reliable readings to ensure access to accurate information in the cath lab.
PressureWire Certus features a proprietary, miniaturized, high-fidelity pressure sensor for measurement of intravascular pressure for accurate FFR measurement. This technology also enables simultaneous measurement of temperature and thermo-dilution low, which can be stored on the RadiAnalyzer Xpress.

The PressureWire Certus is a reliable, accurate FFR measurement system for complex coronary lesion assessment.
Strengthened core 0.014" wire provides increased torque, making PressureWire Certus less sensitive to prolapse.
- Distal polymer sleeve is coated with a hydrophilic outer layer which reduces friction against the vessel wall and increases device compatibility
- A hydrophilic coating enhances overall maneuverability in tortuous vessels by providing better tactile feel and distal access
- The proximal male connector has a hydrophobic coating which increases connector reliability during long procedures
