What am I looking at?
Visual recognition
Self-expanding stent-graft lined with graft material such as ePTFE, producing a covered tubular appearance rather than an open bare-metal mesh.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Fabric-covered self-expanding stent-graft that lines and seals a vessel segment, excluding a stenosis or defect rather than merely scaffolding it. Typical procedural contexts include dialysis-access outflow stenoses and venous lesions where a covered device outlasts bare stenting.
What most clearly distinguishes it from similar devices?
Key distinctions
The graft lining creates a covered conduit within the dialysis circuit, distinguishing a stent-graft from an uncovered bare-metal stent and allowing both scaffolding and sealing.
