Stent-like catheter for isolating a region in a hollow organ of a mammal, and system based on the catheter

A catheter for isolating a region in a mammal hollow organ, comprising:

• an elongate body comprising a proximal end, a distal end, and a central lumen disposed within the elongate body, the elongate body defining a longitudinal axis, both the proximal end and the distal end of the elongate body configured to be inserted into a lumen of the mammal hollow organ, the proximal end defining a first opening of the elongate body and the distal end defining a second opening of the elongate body;
• a plurality of proximal extensions coupled to the proximal end of the elongate body, the plurality of proximal extensions comprising a plurality of individual channels that are continuous with the elongate body such that the plurality of individual channels are embedded within the elongate body;
• two balloons, individually and separately disposed along the elongate body and configured to be inflated to isolate an interior of the hollow organ therebetween;
• a functional channel of the plurality of individual channels comprising one or more functional openings provided in the elongate body between the two balloons, wherein the functional channel is designed to allow:
• a negative pressure to be produced in the isolated interior to take a fluid or gaseous medium therefrom;
• and/or
• a liquid or gaseous medium to be supplied into the isolated interior;
• and
• a second channel of the plurality of individual channels, the second channel extending in the elongate body to deliver a fluid or gaseous medium to at least one of the two balloons to provide inflation thereof.
