Stone extraction balloon 

Another necessary consumable to remove gallstones, which is used during ERCP. In such a way that the catheter enters the bile duct and while the Yalon cuff is empty of air, it passes by the stone (which may be stone fragments caused by crushing by the stone crushing tool) and when the entire cuff is empty, it passes by the stone. Then inflate the cuff of the balloon and by pulling the balloon out of the bile duct, the stones will come out of the poplar and CBD.
