Recognition, context, and distinction

01

What am I looking at?

Visual recognition

Small-bore central venous catheter routed through a subcutaneous tunnel, typically with an external hub and a cuff for tissue ingrowth.

02

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

Use & procedural context

Provides durable small-bore central venous access for long-term antibiotics, infusion therapy, parenteral nutrition, and other chronic venous-access needs when a port or dialysis catheter is not the intended device.

03

What most clearly distinguishes it from similar devices?

Key distinctions

The defining distinction is durable infusion access through a tunneled small-bore catheter, not the large dual-lumen profile required for high-flow hemodialysis.
