Cavis Wirecath® pressure guide wire
Developed and manufactured in Scandinavia
Our goal when developing the Wirecath was to create a pressure guide wire that consistently delivers accurate measurements. Wirecath is the only pressure wire immune to hydrostatic pressure errors, a proven problem with all traditional pressurewires (1, 2, 3). At the same time it gives you unique torque control for easy navigation, even in the most complex anatomies.

Cath lab compatibility and easy integration
Use the FFR software and system from our partner Ortivus and show it on the large screen in your cath lab.
This software also presents pressure-derived CFR (PB-CFR max). Read more about it here.
It is also possible to use any FFR software that is integrated in your recording/monitoring system.

No errors in measurements due to hydrostatic pressure or drift
All traditional sensor-tipped pressure wires are affected by a physical phenomenon causing hydrostatic pressure error (1, 2, 3). The measuring error varies from patient to patient, but the data variation can be significant.
With Wirecath®, the hemodynamic pressure measurements are performed through the fluid-filled interior of the wire, in combination with an external pressure transducer. This is why the Wirecath pressure guide wire is not prone to hydrostatic pressure errors (4, 5) delivering correct, precise measurements.
Moreover, drift is avoided by using the external pressure transducer.

Experience reliable wire performance in tortuous vessels
The torque is transmitted directly to the tip without interference from any inbuilt cables, optical fibers or sensors. The connection rotates freely to the external pressure transducer, to facilitate maximum control and torque response, also in the most complex anatomies. The shapeable and atraumatic soft tip is designed to protect the vessel, without compromising shape retention.
Accurately measure and diagnose
Wirecath® provides accurate and reproducible hemodynamic pressure measurements throughout the entire procedure. The connection of the wire to the transducer is easy to do. After reconnection, the signal is reliable. Pressure measurements remain reliable, also at elevated heart rates.
