The ACIST RXi® Rapid Exchange FFR System, paired with the ultra-thin ACIST Navvus® Rapid Exchange FFR MicroCatheter, gives you flexibility and ease in assessing FFR with your chosen guidewire. Unlike other systems, the RXi® system eliminates the need for a specialized guidewire, allowing the Navvus® MicroCatheter to deliver over your 0.014″ guidewire, helping to ensure maximum control. Wire position can be maintained, even during pull-back assessments of multiple lesions, enabling swift FFR evaluations before, during, and after interventions. The system boasts a user-friendly plug-and-play design, arriving at your tableside in a ready state with the patient’s aortic pressure displayed. Additionally, it requires zeroing only once during initial installation, and the self-calibrating Navvus® MicroCatheter seamlessly integrates with the RXi® console. Leveraging fiber-optic sensor technology, the Navvus® MicroCatheter delivers accurate and reproducible hemodynamic pressure measurements, exhibiting minimal drift compared to traditional pressure-wire systems.
