ACIST RXi® System


RXi and the ACIST Navvus® MicroCatheter give you the freedom to quickly and easily assess Fractional Flow Reserve (FFR) using your 0.014'' guidewire of choice along with a simple and intuitive user interface and flexible mounting configurations.

ACIST Navvus®II Rapid Exchange FFR MicroCatheter


This catheter delivers more flexibility than before and has a streamlined crossing profile to access complex lesions.


Navvus II and its predecessor, Navvus, are the only coronary physiology products that allow the use of your choice of 0.014" guidewires. This market distinction may enable faster, more efficient diagnostic and post-PCI physiological assessments because the wire position is maintained throughout the procedure.

ACIST Diastolic Pressure Ratio (dPR), Non-hyperemic index for coronary physiology


ACIST diastolic pressure ratio (dPR), using the ACIST RXi® Rapid Exchange System and Navvus® MicroCatheter, provides a non-hyperemic alternative for physiological assessment of coronary disease.
