Abstract: An apparatus for operation into the intestine of humans and animals includes a flexible, double-walled tube. The outer wall of the tube is porous for the inward growth of blood vessels, while its inner wall is tight for a barrier effect against the contents of the intestine. A degradable, support structure is advantageously disposed inside the inner wall of the tube.

Abstract: A receptacle for collecting intestinal contents is designed for surgical implant in the abdominal cavity of a patient who, post-operatively lacks the whole or part of the small intestine, large intestiine or the rectum. The receptacle comprises a connection device for connection to the intestine of the patient and an emptying device which is secured in the abdominal wall of the patient. The emptying device realises a closable passage through the abdominal wall. Further, the receptacle includes an inner container (4) or ampoule and an outer casing (3). The inner container or ampoule consists of a gas- and liquid-tight material which is flexible and somewhat elastic. The outer casing (3) consists of a flexible but substantially unstretchable material. The ampoule (4) and the outer casing (3) are united ot one antoher at the connection device and the emptying device.
