Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Wire basket opened within the duct to snare, extract, or push biliary stones and debris toward the bowel, clearing the biliary tree. Typical procedural contexts include retained or recurrent common-duct stones and percutaneous biliary stone clearance.
What most clearly distinguishes it from similar devices?
Key distinctions
The collapsible wire basket captures or repositions intraductal stones and debris, distinguishing it from balloons used for dilation or occlusion and from brushes used for cytology.
