Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Loop snare that lassos and retrieves wires, catheter fragments, or filter hooks and assists through-and-through and body-floss maneuvers. Typical procedural contexts include foreign-body and filter retrieval, catheter-fragment capture, and complex access.
What most clearly distinguishes it from similar devices?
Key distinctions
The loop snare captures a target by encircling and cinching around it, making it the workhorse retrieval tool for free ends, foreign bodies, and devices that can be engaged within a loop.
