Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Single-use catheter-over-needle kit for one-time image-guided aspiration of pleural fluid or ascites for diagnosis or symptom relief. Typical procedural contexts include diagnostic or therapeutic thoracentesis and paracentesis.
What most clearly distinguishes it from similar devices?
Key distinctions
The catheter-over-needle design supports temporary aspiration of pleural or peritoneal fluid rather than long-term indwelling drainage with a locking pigtail or tunneled catheter.
