Implant
First Claim
1. An implant comprising a tubular interior section for implantation into a patient and an exterior section connected to the interior section, wherein the exterior section includes as a separate element a surface comprising a rigid three-dimensional porous structure in contact with the exterior section at an inner circumference thereof, wherein the exterior section comprises a solid body, and wherein the porous structure is permeable, porous in multiple directions and is configured and dimensioned to fit within an inner surface of the solid body with no gap between the porous structure and the exterior section.
