What am I looking at?
Visual recognition
4-5F catheter with a short obtuse angled tip, similar in use to a Kumpe.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Single gentle angled-tip catheter for selecting branch vessels and directing wires in vascular and nonvascular anatomy. Typical procedural contexts include selective vascular access, biliary/GU wire direction, and general angiography.
What most clearly distinguishes it from similar devices?
Key distinctions
The Berenstein’s short, gentle angled tip provides general branch selection and guidewire direction without the larger reverse curves or specialized visceral hooks of more complex catheter shapes.
