Abstract:
1. A device for sealing and draining a natural or artificial intestinal outlet, the device comprising an inflatable balloon with a generally toroidal structure, formed of a flat, everted tube segment whose two ends extend generally coaxially one inside the other and are each connected with their ends to a sleeve, creating a sealed-off volume inside said balloon, whereby the filling of the volume can be adjusted from outside of the body, and creating a draining lumen 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 which is adapted to extend inside the rectum or the intestine of a patient during use, and comprising a trans-anal device portion narrowed with respect thereto, which is adapted to extend through the anus of the patient or his abdominal wall during use, whereby a stiffening sleeve element is positioned inside the draining lumen of said intra-rectal device portion, 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, depending on the filling status of the sealed-off volume, 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 occluded drainage lumen, wherein the stiffening sleeve element extends only inside the intra-rectal device portion and does not extend into said trans-anal device portion.
