What am I looking at?
Visual recognition
Uncovered self-expanding wire-mesh stent, usually nitinol, with open metallic struts and no fabric or graft lining visible between the struts.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Uncovered (bare-metal) self-expanding vascular stent that scaffolds a vessel open after angioplasty or recanalization, allowing tissue to grow through its open struts. Typical procedural contexts include iliac, femoropopliteal, and central venous stenting, including maintenance of patency after dilation or thrombectomy.
What most clearly distinguishes it from similar devices?
Key distinctions
The uncovered nitinol lattice permits tissue and branch interaction through open struts and self-expands after sheath withdrawal, unlike covered stent-grafts or balloon-expandable platforms.
