What am I looking at?
Visual recognition
Very fine, short 0.018-inch guidewire supplied with a micropuncture set, visibly smaller and more delicate than standard 0.035-inch working guidewires.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
First wire advanced through a 21-gauge micropuncture needle to secure initial access and support transition to a working sheath. Typical procedural contexts include arterial and venous access, ports, tunneled dialysis catheters, fistulograms, nephrostomy, and biliary access.
What most clearly distinguishes it from similar devices?
Key distinctions
This is the initial micropuncture guidewire, not a definitive 0.035-inch working rail; its smaller caliber is intended to bridge the 21-gauge puncture to a transitional sheath.
