What am I looking at?
Visual recognition
Reverse-curve catheter with the most compact secondary loop in the Simmons family; the shape reforms in the aorta or aortic arch before selection.

Simmons 1 catheter
Small reverse-curve catheter

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Selects arch, visceral, renal, and mesenteric branch origins when a simple angled catheter lacks the required reach or approach angle.
What most clearly distinguishes it from similar devices?
Key distinctions
Simmons 1 provides the least reach and smallest reforming loop of the common Simmons 1–3 series; Simmons 2 and 3 progressively enlarge the secondary curve.
