Recognition, context, and distinction

01

What am I looking at?

Visual recognition

Catheter with a side-exit port and an advanceable re-entry needle or curved cannula, used under orthogonal fluoroscopy.

02

What does it do, and where will I see it?

Use & procedural context

Dedicated catheter that, after subintimal passage around a chronic total occlusion, directs a needle or wire from the subintimal space back into the true lumen distal to the blockage. Typical procedural contexts include femoropopliteal and iliac chronic total occlusions when the wire tracks subintimally.

03

What most clearly distinguishes it from similar devices?

Key distinctions

The defining feature is a side-exit re-entry mechanism that directs a needle or guidewire from a subintimal track back into the distal true lumen after CTO crossing.
