What am I looking at?
Visual recognition
Flexible drainage catheter with a distal pigtail loop that remains formed by catheter memory rather than an active locking string.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Used for drainage of fluid collections when pigtail retention is desired but a locking mechanism is unnecessary or not part of the selected system.
What most clearly distinguishes it from similar devices?
Key distinctions
Unlike a locking pigtail catheter, the distal loop is not cinched at the hub and therefore depends on its preformed pigtail shape rather than a locking string for retention.
