The present invention discloses a sealing device comprising a sealing tube having proximal and distal ends, the proximal end being adapted to be inserted through an anus of a patient; and a rectal surface mounted at the distal end of the sealing tube and positioned substantially perpendicularly to a cross section of the sealing tube. The rectal surface is configured and operable to create a pressure on the anus externally and activate anal muscles, wherein the rectal surface is placed in contact with the anus when in use.
