Implant and method for its manufacture

摘要

An implant for percutaneous implantation through the abdominal wall for encircling and engaging an externalized length of a body duct of a human or animal patient. The implant has an exterior ring section protruding outwardly from the abdominal wall with a free end which serves for mounting of a detachable device, and an interior section extending through the abdominal wall and inside the patient for internal fixation of the implant. The exterior ring section and interior section have a common axis. The internal circumference of at least a part of the exterior ring section above the interior section is arranged with a biocompatible, integrated ingrowth means for the exterior surface of the body duct wall.
