PressureWire™ X Guidewire

For Wireless Physiology

PressureWire X Guidewire

Objective Decisions.
Simplified Workflow.

Abbott’s newest generation of the PressureWire™ X Guidewire offers objective decisions with a simplified workflow.

The innovative PressureWire™ X Guidewire—the world’s only wireless physiology wire1—can measure pressure and temperature to calculate Abbott's Resting Full-Cycle Ratio (RFR), Fractional Flow Reserve (FFR), Index of Microvascular Resistance (IMR), and Coronary Flow Reserve (CFR). The guidewire’s fully integrated, secure, wireless measurements are integral to a cardiac cath lab’s clinical physiology routine. Abbott’s PressureWire™ X Guidewire and Coroventis CoroFlow Cardiovascular System, the only solution for the cath lab able to detect both epicardial disease and Coronary Microvascular Dysfunction (CMD).2-4

Objective Decisions

  • Innovative sensor housing design offers <1 mmHg/30 min with reduction in drift due to microbubbles5
  • Objective decision-making with both RFR and FFR options
  • RFR has been studied in over 3,500 lesions and 2,000 patients6-10 to show diagnostic equivalence to iFR.
84% reduced drift with the latest PressureWire X Guidewire compared to its previous sensor housing design

Simplified Workflow

  • The PressureWire™ X Guidewire is the world’s only wireless physiology wire1
  • Wireless: from zero to go in 2 easy steps1
  • Ideal for the modern radial approach­
  • Compatible with the QUANTIEN™ Measurement System with an easy touchscreen workflow
  • Compatible with OPTIS™ Imaging Systems for imaging and physiology needs on one platform

2 Steps to Connect the Wireless
PressureWire™ X Guidewire1
  1. Zero. Zero the PressureWire™ X Guidewire by turning on the transmitter.
  2. Go. The transmitter’s function indicator shall display a stable green light when it is successfully zeroed.
