The Acist Navvus II Rapid Exchange FFR MicroCatheter delivers even more flexibility and a streamlined crossing profile to assess complicated lesions.
July 9, 2020 – Acist Medical Systems Inc., a Bracco Group Company, announced the global launch of its Acist Navvus II Rapid Exchange fractional flow reserve (FFR) microcatheter, the second-generation microcatheter for use with its Acist RXi Rapid Exchange FFR System.
FFR measurements provide assessment of arterial lesion severity and inform intervention strategy in both diagnosis and treatment of coronary artery disease. This latest advance delivers the same level of control, consistency and accuracy that physicians have come to expect from the original Navvus microcatheter, with valuable new enhancements. Specifically, the Acist Navvus II features a streamlined crossing contour, 28 percent more flexibility[1] and a lesion entry profile reduced by 15 percent.[2] The result is a highly deliverable microcatheter that may improve procedural efficiency.
The Navvus II Rapid Exchange MicroCatheter and its predecessor, Navvus, are the only coronary physiology products that allow the use of the physician’s 0.014 inch guidewire of choice. This market distinction may enable more efficient, faster diagnostic and post-PCI physiological assessment because wire position is maintained throughout the procedure.
Recently, the FFR-SEARCH study reported an average of 5 minutes per lesion to assess physiology following the intervention using the Acist microcatheter-based system.[3] FFR-SEARCH is a robust and independent, physician-sponsored study that utilized a prospective, all-comers registry and over 600 patients were analyzed.
“This latest advance represents the company’s continued strategic commitment to our market-defining FFR technology,” said Kristen Knox, SVP, general manager, Acist Medical Systems. “Physicians know they can rely on Navvus—and now Navvus II—to easily and quickly guide treatment decisions by invasive physiologic measurement.”
