摘要：
An implant 201 has a tubular interior section 202 for implantation into a patient and an exterior section 203 connected to the interior section. A surface of the exterior section 3 comprises a three-dimensional porous structure 213 at its inner circumference to promote the ingrowth of tissue. The implant has particular use in forming a stable stoma following ileostomy or colostomy. Preferably the porous structure is completely permeable with no deadends, has a thickness of at least 0.5 mm, is made from elements of no more than 500 microns thickness and has openings of no more than 500 microns in diameter. It may be fabricated from interconnecting members of titanium arranged in layers. Preferably the interior section of the implant has an anchoring flange 206 made of hexagonal mesh dividing the interior portion in two. The upper interior portion may be constructed from rods. A biodegradable annular adapter (500, figures 2729) may facilitate connection of a bowel segment to the implant.
