The ACIST RXi® system combines accurate and reliable Fractional Flow Reserve (FFR) measurements with the advantages of Rapid Exchange technology.

Navvus™ ultra-thin MicroCatheter enables maximum control while maintaining wire position.

ACIST NAVVUS RAPID EXCHANGE FFR MICROCATHETER

FIBER-OPTIC ACCURACY

Uses fiber-optic sensor technology that provides accurate and reproducible hemodynamic pressure measurements.

Produces accurate results when compared with traditional pressure-wire systems.

LESS SIGNAL DRIFT

More stable with respect to signal drift.

Almost 60% less signal drift with Navvus MicroCatheter when compared to the pressure wire.10

CORRELATION WITH PRESSURE WIRES

FFR measured using the Navvus MicroCatheter is nearly identical to that of the pressure wire.10

Small size difference between the Navvus MicroCatheter and the pressure wire has minimal impact on the accuracy of FFR.10
