Recognition, context, and distinction

01

What am I looking at?

Visual recognition

Stiff metal or plastic rod with a bullet tip and a coupling that grips the catheter end.

02

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

Use & procedural context

Creates the subcutaneous tract through which a tunneled catheter is drawn from the venotomy to a separate skin exit site. Typical contexts include tunneled dialysis catheters, tunneled small-bore lines, and implanted port catheters.

03

What most clearly distinguishes it from similar devices?

Key distinctions

The tunneler creates the subcutaneous course that separates the venotomy from the external exit or pocket, distinguishing it from the catheter that ultimately occupies that tract.
