Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Provides stable selective access and a supportive conduit for guidewires, microcatheters, balloons, stents, and other interventional devices during vascular procedures that require a stronger proximal platform than a diagnostic catheter alone.
What most clearly distinguishes it from similar devices?
Key distinctions
A guiding catheter provides greater lumen capacity and proximal support for interventional device delivery than a routine diagnostic catheter, while still allowing selective positioning at the target vessel.
