Device for sealing and drainage of a natural or artificial intestinal outlet

A device for sealing and draining a natural or artificial intestinal outlet, the device comprising an inflatable balloon (2) with a generally toroidal structure, formed of a flat, everted tube segment whose two ends (5,6) extend generally coaxially one inside the other and are each connected with their ends (7, 8) to a sleeve (9), creating a sealed-off volume (10) inside said balloon (2), whereby the filling of the volume (10) can be adjusted from outside of the body, and creating a draining lumen (13) radially inside an inner layer of said everted balloon, an outer layer of the everted tube segment comprising a radially expanded intra-rectal device portion (101) which is disposed inside the rectum or the intestine of a patient during use, and comprising a trans-anal device portion (102) narrowed with respect thereto, which extends through the anus of the patient or his abdominal wall during use, whereby a stiffening sleeve element (14) is positioned inside the draining lumen (13) of said intra-rectal device portion (101), keeping the lumen open and facilitating the uptake and passage of feces through the intra-rectal segment of the draining lumen, while the two concentric tube layers of said trans-anal device portion (102), depending on the filling status of the sealed-off volume (10), can either be collapsed inside the anal channel to a small diameter, thereby forming a non-dilating structure, but allowing for free spontaneous passage of feces, or can unfold and erect inside the anal channel, thereby forming a trans-anally sealing structure with the occluded drainage lumen (13).
