Surefire Medical, Inc., based in Westminster, Colo., was founded in 2009 to develop innovative infusion systems for the Interventional Radiology and the Interventional Oncology markets. SurefireÍs technology is designed to precisely deliver embolic agents through a unique microcatheter with an expandable tip, which collapses during forward flow to allow normal blood flow to carry therapy as close to the tumor as possible. In reverse flow, when drugs/microspheres are being delivered by the system, the tip automatically and dynamically expands to the vessel wall, creating a pressure gradient that drives the therapeutic agents deeply into the tumor while blocking backflow that might damage healthy tissue. The Surefire Infusion Systems and Surefire Precision have received regulatory approval in the U.S., Europe, Canada, Australia, New Zealand, Taiwan, Mexico and Brazil.
