Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Establishes and preserves arterial or venous access for angiography and intervention, with sheath size selected to accommodate the planned catheter or device.
What most clearly distinguishes it from similar devices?
Key distinctions
The vascular introducer sheath is primarily a short working-access platform; unlike a long guiding sheath, it is not designed to provide extended distal support near the treatment target.
