Cavis Wirecath®

World’s first pressure guide wire eliminating hydrostatic error

A new level of precision in assessment of coronary artery disease

Increase
your measuring accuracy

Measurement results you can truly rely on, with immunity to hydrostatic errors.

Achieve
unique torque control 

Fingertip torque response in tortuous vessels.

Trust your
diagnosis

Experience true precision
to confidently diagnose your patients. 

Obtain precise measurements, without hydrostatic pressure errors for the first time ever

Unlike traditional sensor-tipped wires, the Wirecath® is immune to hydrostatic pressure errors (1, 2, 3). Hemodynamic pressure measurements are performed through its fluid-filled interior and an external pressure transducer, eliminating the errors caused by hydrostatic pressure (4). 

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 shapeable and atraumatic soft tip is designed to protect the vessel, without compromising shape retention.

Confidently diagnose and treat your patients 

In a challenging clinical situation, you need measurements you can trust and a tool that performs well and is easy to use. Cavis Wirecath® is developed with one goal in mind – to provide simple, accurate measurements for confident decision making, every single time.
