A method of removing an obstruction in the biliary duct including the steps of providing a coaxial catheter device comprising an inner catheter having a proximal end and a distal end wherein at least two or more lumens are formed between the proximal end and distal end of the inner catheter. The method includes providing an outer catheter having a proximal end and a distal end and an opening wherein the inner catheter is coaxially engaged through the opening of the outer catheter thereby forming a coaxial space between the inner catheter and the outer catheter wherein at least one of the two or more lumens is configured for receiving a fluid for inflating a balloon, at least one of the first lumen and the second lumen is configured for receiving a wire guide and the coaxial space is configured for receiving a flushing fluid for the removal of an obstruction within the biliary duct.
