Wireless FFR Eliminates Extra Cable, Aids Stenting Decisions


October 20, 2008

St. Jude Medical's wireless PressureWire Aeris measures fractional flow reserve (FFR) to determine if blood flow is adequate in stenosised vessels and if a stent is needed. It was the first wireless FFR device introduced to help reduce wire obstructions in the cath lab.

FFR helps guide percutaneous coronary interventional (PCI) procedures for improved patient outcomes and lower cost. FFR is an index for functional severity of coronary stenosis based on blood pressure flowing around a lesion. The technology helps identify which lesion or lesions are responsible for a patient’s ischemia, enabling a cardiologist to make more informed choices as to which areas to treat, instead of relying on images of the vessels alone.
