1. A percutaneous ostomy implant for implantation into the abdominal wall of a patient, the implant comprising:
- a cylindrical part for mounting an external detachable device thereto;
an ingrowth mesh; and
a circular flange for anchoring the implant;
wherein the cylindrical part and circular flange are attached to opposite ends of the ingrowth mesh;
wherein the ingrowth mesh has an exterior surface that is exposed and completely unobstructed to allow direct and unbroken contact with the abdominal wall in the region adjacent to the circular flange as well as adjacent to the epidermis, thereby permitting tissue ingrowth through the mesh from its attachment to the flange to the skin surface, andwherein the cylindrical part is spaced sufficiently from the flange axially such that when the implant is implanted in the abdominal wall of a patient, the ingrowth mesh is arranged to meet and contact the epidermis of the patient so that the epidermis can infiltrate the ingrowth mesh and attach therethrough directly to serosal tissue of a bowel segment located inside the implant.

Abstract
A percutaneous ostomy implant for implantation into the abdominal wall of a patient. The implant has a cylindrical part for mounting an external detachable device thereto, an ingrowth mesh and a circular flange for anchoring the implant. The cylindrical part and circular flange are attached to opposite ends of the ingrowth mesh. The ingrowth mesh is arranged such that when the implant is implanted in the abdominal wall of a patient, the epidermis meets the ingrowth mesh and is able to attach therethrough directly to serosal tissue of a bowel segment inside the implant.

- 16. In a percutaneous ostomy implant, the improvement comprising an ingrowth mesh structure configured in use to surround a vessel having serosal tissue, a cylindrical part at one end of the mesh structure and a circular flange at the opposite end of the mesh structure for anchoring the implant, wherein the ingrowth mesh has an exterior surface that is exposed and completely unobstructed to allow direct and unbroken contact with the abdominal wall in the region adjacent to the circular flange as well as adjacent to the epidermis, thereby permitting tissue ingrowth through the mesh from its attachment to the flange to the skin surface, and wherein the ingrowth mesh is arranged to be spaced sufficiently axially away from the flange in order to meet and contact the epidermis of the patient and to allow the epidermis of the abdominal wall to infiltrate the ingrowth mesh and attach directly to the serosal tissue in the implant through the ingrowth mesh.
