ChromaFlo is appropriate for peripheral and coronary vessels, including left main, bifurcations, superficial femoral artery, and iliac. It is designed to make lumen size and stent apposition instantly recognizable and helps identify branches, dissections, thrombus, and plaque distribution in bifurcations. ChromaFlo is compatible with Philips' Eagle Eye Platinum plug-and-play digital IVUS catheters and Visions PV .018 and .014 catheters.
