Wirecath®
Combined guidewire/catheter

The ”open wire” technology creates a new level of precision

The new Wirecath® is a pioneering 0.014″ pressure wire. Hemodynamic pressure measurements are performed through its water-filled interior and an external pressure transducer.

Accurate, by avoiding drift and the hydrostatic error

Unlike all sensor-tipped wires, the Wirecath® is not liable to the so-called hydrostatic error. Moreover, drift is avoided by using the compatible transducer according to the IFU. Explore more here.

Cath lab compatibility and easy integration

No additional hardware is needed in your lab. Use the compatible transducer according to the IFU, and the integrated FFR software of your system to measure physiological indices such as resting Pd/Pa, FFR, and do research in pressure-derived CFR.

Device description

Why choosing Wirecath?

Experience torque control and steerability

  • Through Wirecath´s ”open wire” concept, the torque is transmitted directly to the tip without interference from any inbuilt cables, optics or sensors.
  • The freely rotating connection to the external pressure transducer facilitates control and torque response.
  • As shown in the video, Wirecath shows enhanced torqueability compared to the competition.

Tortuous vessel maneuverability

  • The distal part has a hydrophilic coating simplifying vessel navigation and provides rail support for interventional devices.
  • The durable soft tip is designed to protect the vessel in tortuous anatomy without compromising the shape retention.
  • As shown in the video, Wirecath´s ”open wire” concept allows continuous flexibility since no built-in electronics, optics or sensors are required as in sensor-tipped pressure wires.

Signal reliability

  • Wirecath® provides accurate and reproducible hemodynamic pressure measurements throughout the entire procedure.
  • Pressure measurements remain reliable, also at elevated heart rates.
  • The connection of the wire to the transducer is easy to do.
  • After reconnection, the signal is reliable.

Immunity against the hydrostatic error

  • Unlike available sensor-tipped wires, the Wirecath® is not liable to the so-called hydrostatic error.
  • This error is caused by the natural force of hydrostatic pressure1 and will cause 24% of vessels to be misclassified
    (16% at hyperemia, 24% at resting Pd/Pa 2, 3, 4, 22% at dPR 4, 5).
