Abstract
The present invention provides an improved pressurization device for use with angioplasty balloon catheters, or the like. The device has a novel quick release mechanism which enables rapid advancement of a threaded screw plunger to attain initial pressurization, and then the subsequent engagement of said mechanism with the threaded surface of the plunger to achieve precise control during final pressurization of the balloon catheter. In addition, there is provided an improved and novel pressure indicating means for providing the physician with an analog readout of the pressure being applied to the balloon catheter.
