Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Catheter that mechanically removes or modifies plaque, by directional cutting, rotational or orbital sanding, or laser, to debulk stenoses and improve balloon and stent results. Typical procedural contexts include calcified or diffuse peripheral arterial disease, especially femoropopliteal and infrapopliteal lesions.
What most clearly distinguishes it from similar devices?
Key distinctions
Atherectomy modifies or removes plaque through a powered mechanical mechanism before or alongside balloon and stent therapy, rather than treating the lesion by dilation alone.
