Abstract
A stoma-prolapse prosthesis includes a single plastic piece configured as two flexible open rings with spokes tied together at their centers by a central stem. When in place for use, one of the two flexible open rings is collapsed between the fingers and inserted inside the stoma and pushed through to the interior of the abdominal wall. The central stem is sized to be just long enough to match the thickness of the abdominal wall around the stoma. The other of the two flexible open rings self-locks around the perimeter of the stoma on the outside skin surface. The inside one of the two flexible open rings takes up the tissue slack caused by the prolapse, and the spokes inside block the bowel tissues from pushing through.
