ABSTRACT:
A device for use in cholangiography and similar procedures comprising, a first syringe having a barrel defining a chamber for retaining an irrigation liquid, and a plunger having one end received in the chamber for pumping the liquid from the chamber. The device has a second syringe having a barrel defining a chamber for retaining a liquid contrast medium, and a plunger having one end received in the chamber of the second syringe for pumping the contrast medium from the chamber. The device has a catheter having a distal end, a proximal end, and a lumen extending through the catheter. The device also has means for connecting the proximal end of the catheter to the chambers of the first and second syringes without exposing the liquids to the atmosphere intermediate the lumen and chambers, in order that the irrigation liquid and contrast medium may be ejected through the catheter without introduction of air into the device.
