Abstract
A pressure device for use with a balloon angioplasty catheter includes a housing, a syringe body, rubber stopper and a pressure gauge. The rubber stopper is connected to a threaded plunger leading to a handle. The threaded plunger is engaged by a half nut. The half nut may also be disengaged. A forward located thumb button controls the engagement of the half nut with the threaded plunger. The initial operation of the thumb button also irreversibly illuminates the pressure gauge.
