<p>CHOLANGIOGRAPHY DEVICE AND METHOD A device for use in cholangiography and similar procedures comprising, a syringe having a barrel defining a chamber. The syringe has a plunger having one end received in a proximal end of the syringe chamber for pumping liquid from the chamber, a floating barrier received in the chamber and defining a first compartment intermediate the barrier and a distal end of the chamber for retaining an irrigation liquid and a second compartment intermediate the barrier and the one end of the plunger for retaining a liquid contrast medium. The device has a catheter having a distal end, a proximal end, and a lumen extending through the catheter. The device has a liquid receiving receptacle having a chamber, means for selectively connecting the syringe to the catheter lumen and the receptacle chamber, and means for establishing communication between the connecting means and the second compartment when the barrier is located adjacent the distal end of the chamber.</p> |
