Abstract: Some embodiments are directed to a probe system for endoluminal negative pressure therapy with a probe tube, and a probe body, connected with the probe tube, which includes a basic body with an inner lumen and with at least one opening which leads from the inner lumen through an outer wall of the basic body to an outer side of the basic body, in which the probe body includes on the outer side of the basic body several rod-form structures and/or at least one lamella-form structure.

Abstract: A probe for monitoring a pressurised process space includes a casing enclosing a cavity and having a first window configured to be brought into contact with the process space, and a second window. A sealing means is configured to seal the first window to the casing. At least once coupling line is disposed within the cavity between the first and second windows and is configured to guide electromagnetic radiation entering through one of the two windows to the other of the two windows. A method for monitoring a pressurised process space, in which one or more hazardous substances occur, is also disclosed.
