Abstract
A biocompatible implantable portal is provided that has a wall defining a communicative passage through an interior bore. The exterior of the portal has a neck region adapted to promote autologous cell growth on the neck region. A series of channels are provided on the exterior neck region to facilitate autologous cell growth while disfavoring fluid pooling and bacterial growth. Typical channel widths are from 20 to 300 microns, with adjacent channels being separated by plateaus having a width of between 0 and 600 microns. Providing the portal exterior neck region with a texture varying on a nanometer length scale facilitates autologous cell growth. Applying a coating such as a tissue scaffolding matrix to the neck region prior to implantation also facilitates cell growth. A coupling or a manifold encompassing the neck region facilitates the draw of vacuum and/or mechanical protection for the growing cells.
