An inflation device for a balloon catheter has a pistol grip type handle with a trigger for releasing a screw plunger to enable rapid inflation and deflation of the balloon catheter. The trigger bias and thread angle of mating threads are selected to automatically release the plunger when a safe balloon catheter pressure is exceeded. A trigger guard is slidable over the trigger to prevent accidental operation and pressure release.
