ABSTRACT The present invention relates to a device for permanent establishment of a connection between the abdominal cavity or an organ located in the abdominal cavity and the exterior of the body, for instance for chronic peritoneal dialysis or other forms of treatment in respect of the abdominal cavity. The device is made of commercially pure titanium or is at least coated with titanium on the surfaces coming into direct contact with abdominal wall tissue. The healing-in of the device takes place preferably in two stages so that during an unloaded healing phase it is able to heal into the connective tissue of the abdomen and, within the abdominal cavity, the peritoneum, and so that only thereafter is the skin pathway made and the device actually in use. The device comprises a first anchorage portion arranged to be implanted into the connective tissue of the abdomen at the first operation, a covering screw with plug to block the pathway opening in the anchorage portion during the healing phase and a skin passage in the form of a titanium tube for connection to the anchorage por- tion at the second operation after prior removal of the covering screw with plug.
