Assessment of Catheter-based Interrogation and Standard Techniques for Fractional Flow Reserve Measurement

"Provide hemodynamic information for the diagnosis and treatment of coronary and peripheral artery disease. The system is intended for use in catheterization and related cardiovascular specialty laboratories to compute and display fractional flow reserve or FFR.~Measurement of FFR requires simultaneously monitoring the blood pressures proximal and distal to a lesion. The RXi system includes a single use catheter (Navvus) with a pressure sensor for acquisition of the distal pressure. The proximal pressure is acquired by the guide catheter via an interface to the hospital hemodynamic monitor.~The Navvus catheter interfaces to the RXi system console which includes embedded software, a user interface touch screen and associated electronics."
