First Procedures With Avinger's Next-Generation Pantheris Lumivascular System Performed in Europe
January 3, 2018—Avinger, Inc. announced the successful treatment of the first seven patients with its next-generation Pantheris Lumivascular atherectomy system. The procedures were performed by Arne Schwindt, MD, a vascular surgeon at St. Franziskus Hospital in Münster, Germany. The company noted that the patients presented with a variety of lesion types in arteries above and below the knee, including in-stent restenosis, a calcified lesion, and a chronic total occlusion.
In the company's announcement, Dr. Schwindt commented, “Next-generation Pantheris with real-time image guidance enabled me to see the stent struts and precisely target and remove substantial amounts of tissue that had grown into the stent. In two patients, the disease extended below the knee. Image-guided atherectomy with the next-generation Pantheris made it possible to precisely target and remove atherosclerotic plaque in this region while conserving the deep wall components and thus reducing the risk of perforations in these small vessels. The angiographic outcome was excellent.”
According to Avinger, the design of the next-generation Pantheris includes a simplified single-balloon system for both apposition of the device and occlusion of blood flow, a stiffer shaft for increased pushability, a more robust nose cone with the option for more tissue storage capacity, and an enhanced cutter design. The company's Lumivascular technology allows physicians to see from inside the artery during an atherectomy procedure by using optical coherence tomography that is displayed on Avinger’s Lightbox console.
The device is available in limited supply for commercial sale in the European Union. It is not available commercially in the United States, advised the company.
