Percutaneous abdominal implant
First Claim
1. 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.

Abstract
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 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 for mounting of a detachable device, an interior section defined by an circumferential interior wall adapted to extend through the abdominal wall and inside the patient for internal fixation of the implant, wherein the exterior tubular section and the interior section have a common axis A. The circumferential exterior wall of the exterior tubular section and the circumferential interior wall of the interior section are arranged axially spaced apart at a distance D from each other to provide an axial gap between opposing free ends of the exterior tubular section and the interior section, with the exterior tubular section and interior section being connected inside the sections.

19. 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 radially extending anchoring flange for anchoring the implant inside the body, 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 a rigid ingrowth structure comprising circumferentially spaced ribs having a suitable length to keep opposing free ends of the exterior tubular section and the interior section spaced apart at a defined and permanent suitable distance corresponding to the open gap with the ribs sufficiently spaced apart to substantially or completely prevent formation of a biofilm between the exterior and interior sections.

-
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 a rigid ingrowth structure comprising circumferentially spaced rigid connecting members that maintain the exterior tubular section and interior section spaced by the open gap with the connecting members being spaced apart or having sufficient openings to substantially or completely prevent formation of a biofilm between the exterior and interior sections. - View Dependent Claims (21)
