What is it about?
This study explores how to safely deliver cold plasma inside the body using a flexible catheter. By adjusting the distance between the plasma source and target tissue, the researchers ensure the plasma remains effective without overheating or electrical risk. The device shows promise for treating cancers like cholangiocarcinoma using endoscopy.

Why is it important?
This is the first in-depth study of plasma behavior in a flexible catheter designed for medical endoscopy. It establishes safe and effective operating conditions for clinical use. The results are timely as plasma-based therapies are moving closer to human trials, particularly for hard-to-treat cancers like those in the biliary tract.
Perspectives
This work marks a major step in translating plasma physics into clinical tools. We are proud of how we bridged engineering and medicine, creating a device that performs safely under extreme conditions. It opens real possibilities for treating deep-seated tumors with minimal invasion.
