What am I looking at?
Visual recognition
Pre-shaped catheter with a Cobra-family downgoing hook and a shallower, less pronounced secondary curve than a Cobra 2.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Selects aortic branch vessels with caudal or oblique origins, including celiac, mesenteric, renal, adrenal, and other visceral branches. Typical contexts include visceral angiography, embolization, and venous sampling.
What most clearly distinguishes it from similar devices?
Key distinctions
The Cobra 1 is the smaller, shallower member of the Cobra family; compared with a Cobra 2, it offers less hook depth and reach while retaining direct downgoing selection.
