Invatec announced that it has received US FDA 510(K) approval to market its Amphirion Deep 150 mm Long PTA Balloon and Tapered 210 mm Long PTA Balloon in the United States. The Amphirion Deep Long Balloons will extend the Amphirion Deep family of dedicated below the knee (BTK) PTA catheters, which are specifically designed to reach, access and treat arteries below the knee. The introduction of these two Long Balloons will help physicians to reach and treat arteries in the feet more easily than ever before. The 150 mm and Tapered 210 mm Long Balloons have same unique design and quality features as the rest of the Amphirion Deep product line and are indicated to dilate stenoses in the femoral, popliteal and infra-popliteal arteries. The unique Tapered 210 mm Long Balloon is anatomically-designed to ensure more precise balloon-to-vessel conformability in the narrowed and tapered distal regions of the leg and foot. The entire Amphirion Deep line is 4 French compatible and features a differentiated shaft diameter designed to promote flexibility and trackability without compromising the balloon’s pushability. Invatec’s Amphirion line also boasts a low-profile, enabling ease of crossability. The Amphirion Deep BTK PTA Balloon Catheter line is available in diameters of 1.5 – 4.0 mm and 20 – 210 mm in length in the US.
