Summary

This study will test a new, disposable freezing catheter (Celsio) in 30 people who need a lung procedure. The catheter uses extreme cold to help diagnose or treat conditions like lung cancer and interstitial lung disease. Unlike current devices, it does not need a bulky console or gas tanks. Researchers want to see if it works reliably and safely in real-world use.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Disposable Celsio Flexible Cryocatheter System
What this could lead to: If successful, this could provide a simpler, more affordable tool for diagnosing and treating lung conditions like tumors and interstitial lung disease.
What could go wrong: This is a very early, small study (30 people) with no comparison group. It only tests one device, so results may not apply to other tools or settings. Risks include bleeding or lung collapse.
