Alwide Plus Balloon Catheter is a non-compliant balloon dilatation catheter specifically designed for TAVI procedures. It enables precise and controlled dilation with minimal risk of over-expansion. Featuring a low compliance value of 105.55%, a high burst pressure of 8 atm, and 30% greater strength, it ensures safety and effectiveness even in heavily calcified valves. The reinforced double lumen and soft tip enhance advancement and handling, while radiopaque markers facilitate accurate placement. Available in diameters of 16, 18, 20, 22, 24, 26, and 28 mm, with a length of 40 mm and a fill volume of 12–33 ml, the Alwide Plus catheter is a reliable choice for both pre- and post-dilatation in TAVI procedures.
