What am I looking at?
Visual recognition
Needle or small catheter connected to fluid or gas delivery tubing and positioned between the ablation target and a vulnerable adjacent structure.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Creates temporary protective separation between an ablation target and adjacent vulnerable structures by instilling fluid for hydrodissection or gas for pneumodissection during thermal ablation.
What most clearly distinguishes it from similar devices?
Key distinctions
The system’s purpose is protective tissue displacement rather than ablation itself; hydrodissection uses fluid and pneumodissection uses gas to create temporary separation from vulnerable structures.
