VesSpiral® Ultra Spiral Twin-Wall Ultra High Pressure PTCA Balloon

VesSpiral® Ultra is a Rapid Exchange Spiral Twin-Wall super high-pressure balloon catheter. The Spiral Twin-Wall balloon comprised of a noncompliance balloon inside a low profile spiral balloon, making the balloon highly noncompliant and super high pressure. The spiral elements are integrated and uniformly distributed across the balloon surface during balloon forming. Under low inflation, the convex of Spiral create highly localized points of contact with calcium and amplification of force to create deep and wide fractures based on Hertz Contact Stress mechanism, with inflation pressure increased, the concave of Spiral expanded outward, continuing fracture the remaining calcified lesion, Spiral balloon's unique programmed dilation mechanism make vessel dilated uniformly and the injury minimized.
