The Merit basixTAU™ Inflation Device is a 20mL disposable device fitted with a threaded plunger assembly with lock/ release bar, a flexible high-pressure extension tube, and a three-way medium pressure stopcock. The basixTAU is designed to generate positive and negative pressure, and monitor positive pressures over a range of zero to +30ATM/BAR (zero to +441 PSI). The basixTAU has an added “fold-out” handle feature designed to provide a secondary mechanism for turning the handle during inflation and deflation of angioplasty balloons or other interventional devices.
