Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Compliant balloon inflated within the duct to block flow and force contrast to opacify the entire biliary tree for leak, stricture, or anatomy assessment. Typical procedural contexts include biliary leak localization, stricture mapping, and post-surgical ductal anatomy.
What most clearly distinguishes it from similar devices?
Key distinctions
Its purpose is temporary ductal occlusion during contrast injection, not stricture dilation; the inflated balloon redirects contrast to improve cholangiographic opacification.
