Abstract
A cholangiography catheter is used in the surgical removal of gall stones so that contrast liquid may be temporarily retained in the location of a patient's bile duct in order to take X-ray pictures of the bile duct. The catheter is a flexible and resilient 'T'-shaped member having two air inflatable balloons, each connected in an arm of the catheter. The balloons may be independently inflated to close the drain lumen of the catheter and the bile duct.
