Avinger announces three additions to U.S. intellectual property portfolio
Avinger announced three recent additions to its U.S. intellectual property portfolio. The U.S. Patent and Trademark Office has issued U.S. Patent No. 9,854,979, titled "Chronic Total Occlusion Crossing Devices with Imaging." In addition, the USPTO has provided an Issue Notification for U.S. Patent Application No. 13/752,325, titled "Catheter System and Method for Boring Through Blocked Vascular Passages," which is expected to issue as U.S. Patent No. 9,918,734 on March 20, 2018 and has provided a Notice of Allowance for certain claims in U.S. Patent Application No. 14/433,786, titled "Occlusion-Crossing Devices." All three of these patents relate to Avinger's portfolio of technologies used for crossing completely blocked arteries, also referred to as chronic total occlusions or CTOs, in both the peripheral and coronary arteries. The Company's Ocelot device is the only image-guided CTO-crossing catheter cleared for sale in the U.S. by the FDA. It demonstrated 97% success in crossing CTOs in peripheral arteries and a 98% freedom from major adverse events in the 100-patient CONNECT II study, which supported the device's FDA clearance in 2012.
