Claim:
A percutaneous implant for encircling and engaging an externalised length of a body duct of a human or animal patient, comprising: an exterior tubular section defined by an circumferential exterior wall at least a part of which is adapted to protrude outwardly from the abdominal wall with a free end which serves for mounting of a detachable device; an interior section adapted for internal fixation of the implant, with the interior section comprising a tubular member having a free end adjacent the free end of the exterior tubular section, and a radially extending anchoring flange for anchoring the implant inside the body, wherein the exterior tubular section and the interior section have a common axis A, with the exterior tubular section and the interior section arranged axially spaced apart from each other to provide an axial open gap that is parallel to the common axis A and that is delimited by the free end of the exterior tubular section and the free end of the tubular member, wherein the exterior tubular section and interior section are connected to each other by an ingrowth structure comprising a rigid ingrowth mesh or a plurality of rigid members, which mesh or plurality maintains the exterior tubular section and interior section spaced by the open gap and provides passageways, channels or openings that substantially or completely prevent formation of a biofilm between the exterior tubular and interior sections.
