Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Very stiff fixed-core rail wire used to straighten tortuosity and support large-bore sheaths and endograft delivery. Typical contexts include EVAR/TEVAR, complex large-bore venous interventions, and other procedures requiring maximal rail support.
What most clearly distinguishes it from similar devices?
Key distinctions
Its exceptionally rigid shaft provides a stable delivery rail for large-bore devices, with substantially less flexibility than Amplatz or Bentson working guidewires.
