The multi-stage balloon provides three distinct sizes at set pressures and features little to no waisting. The clear material and balloon design supports visualization throughout the procedure. The single-stage nylon balloon provides high tensile strength and accurate sizing, at the maximum pressure, with no waisting. Balloons are available in sizes from 6 to 20 mm with a pre-loaded 0.035 in. guide-wire, to facilitate placement in complex strictures or tortuous anatomy.
