Coherex Medical out of Salt Lake City, Utah won the CE Mark to commercialize the firm’s percutaneous endovascular FlatStent EF™ in the European market. The device is designed for closing the Patent Foramen Ovales (PFO).
About the device from Coherex:
The Coherex FlatStent EF device is similar in use and function to self-expanding vascular stents that are widely used around the world by interventional cardiologists. However, the patent-pending Coherex FlatStent EF device combines a planar Nitinol™ structure with a polyurethane substrate in a unique fusion of PFO closure mechanisms designed with the intent to naturally seal PFO tunnels.
According to Coherex President and CEO, Richard J. Linder, the Coherex FlatStent EF is the first device cleared for use to close a PFO from within the PFO tunnel.
“Although there are a handful of older, legacy devices cleared for closing PFOs, these devices are significantly larger than the Coherex FlatStent EF and they close PFOs by completely overlapping PFO openings on both sides of the septal wall,” Linder said. “Conversely, by its very design, the Coherex FlatStent EF represents the next generation approach to PFO closure. The Coherex FlatStent EF has dramatically less mass and less exposed surface area than other PFO closure systems and it is deployed almost entirely within the PFO tunnel (the only exception being two tiny anchors). As a result, the Coherex FlatStent EF uses a body’s natural defenses to enclose its polyurethane foam and Nitinol metal structure and thereby close the PFO opening from within the PFO tunnel. We believe this technology will be much safer for patients during the long term and reduce or eliminate safety concerns that are associated with older technologies."
EASE OF USE
