ABSTRACT:
An inflation/deflation device for an angioplasty balloon catheter which permits quick inflation to an approximate working pressure followed by a fine but slower adjustment to a final desired pressure. The device includes a housing containing a syringe of the type having a cylindrical chamber containing a piston. A specially designed plunger extends from the proximal end of the housing whereby the initial approxiate pressure can be achieved by the hand-squeezing of the plunger and a slight rotation of that plunger is used to maintain the plunger in a locked disposition. An internal shaft is disposed within the tubular plunger and its distal end is secured to the syringe's piston. The internal shaft includes a threaded segment on its exterior surface engaging a correspondingly threaded surface on the interior of the plunger such that rotation of the shaft relative to the plunger causes axial movement of the piston within the syringe.
