What am I looking at?
Visual recognition
Very large-caliber vascular sheath with a robust hemostatic hub and a long tapered dilator, visually scaled for large-profile delivery systems rather than routine diagnostic access.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Large-diameter introducer for delivering big-profile systems such as PE or venous thrombectomy devices, venous stents, or endografts. Typical procedural contexts include PE and iliocaval thrombectomy, EVAR/TEVAR, and large venous interventions.
What most clearly distinguishes it from similar devices?
Key distinctions
The defining distinction is delivery profile: this sheath is sized for large-bore thrombectomy, venous stenting, or endograft systems rather than routine diagnostic or small-device access.
