Abstract

A system for treatment of a target region of lung tissue including: a flow regulator configured to be interposed between a conductive fluid source and a conductive fluid outlet positionable at or in proximity of the target region of lung tissue, the flow regulator being further configured for controlling a flow rate or a bolus quantity of conductive fluid coming from the fluid source and delivered to the conductive fluid outlet; and a controller communicatively connectable with said flow regulator and with at least one sensor, with the at least one sensor being configured for detecting values taken by at least one control parameter representative of a physical property, wherein the physical property is one of temperature (T), pressure (p), electric impedance (Z), or electric conductivity (C) of material present at or in proximity of the target region of lung tissue. A solution which may be delivered using the system is also disclosed.
