Can a new basket catheter clear large bile duct stones better?

This trial compares two devices used to remove large bile duct stones (10 mm or larger): the Vortic Catch V basket catheter and a standard basket catheter. The goal is to see which device clears more stones completely and whether one is faster or safer. About 100 people with known or suspected large bile duct stones will be randomly assigned to one of the two devices during a procedure called endoscopic papillary large balloon dilation. The study will measure how many stones are cleared, total procedure time, and any complications within 30 days.
