The company s IVUS offerings are used by clinicians to produce a cross-sectional image of the artery and provide information on the composition and density of plaque or lesions caused by the accumulation of fat-laden cells in the inner lining of the artery. Its FM products include consoles and single-use pressure and flow guide wires. These offerings are used to gauge the impact of arterial plaque on blood flow and pressure.
