13. A vacuum sponge system, comprising:
a sponge having an open-pore structure, an outer surface, a proximal end and a distal end, spaced from the proximal end in an axial direction of the sponge;
a drainage tube disposed at least partially in the sponge, wherein the drainage tube is in fluid communication with the sponge;
wherein the drainage tube is connectable with a vacuum pump such that a pressure generated by the vacuum pump is applicable to the outer surface of the sponge via the drainage tube; and
a delivery member having an outer surface and extending in an axial direction of the sponge and adapted to establish a fluid communication between a region distal from the distal end of the sponge and region proximal from the proximal end of the sponge in a condition where the pressure provided by the vacuum pump via the drainage tube is applied to a vicinity of the outer surface of the delivery member and the outer surface of the sponge, wherein the delivery member is disposed at least partially radially outside of the sponge,
wherein the vacuum sponge system is to be used in gastro-intestinal lumens of human bodies that are a deeper than 10 cm as seen from a body orifice inside a human body.
