<p>An implant (1;20) serves for percutaneous implantation through the abdominal wall for encircling and engaging an externalised length of a body duct of a human or animal patient. The implant (1;20) is of the kind comprising an exterior tubular section (2) defined by a circumferential exterior wall (2') at least a part of which is adapted to protrude outwardly from the abdominal wall with a free end (5) which serves for mounting of a detachable device, an interior section (3) defined by a circumferential interior wall (3') adapted to extend through the abdominal wall and inside the patient for internal fixation of the implant (1;20), wherein the exterior tubular section (2) and the interior section (3) have a common axis A. The circumferential exterior wall (2') of the exterior tubular section (2) and the circumferential interior wall (3') of the interior section (3) are arranged axially spaced apart at a distance D from each other to provide an axial gap (18) between opposing free ends (7;8) of the exterior tubular section (2) and the interior section (3), said exterior tubular section (2) and interior section (3) are connected by means of distance means (10;21) extending inside the sections (2,3).</p> |
