Abstract:
1. A medical apparatus comprising: (a) a hub component comprising: an upper wall and side walls adjoining the upper wall along upper ends of the side walls, the upper wall and side walls together defining an open hub interior region; a hub inlet through the upper wall along a hub inlet axis into said hub interior region; a hub outlet along a hub outlet axis from said hub interior region through one of the side walls of the hub component at a location intermediate between the upper end and a lower end of the side wall, said hub outlet axis being transverse to the hub inlet axis; and a hub porous tissue ingrowth surface at least along a portion of the upper wall surrounding the hub inlet; and, (b) a transcutaneous hub tube having an outer surface and providing an interior conduit, the hub tube slidably mating with said hub inlet during an implantation procedure to establish a transcutaneous tube portion having an adjustable length between the skin surface and the hub inlet when the hub component is implanted, said hub tube having a tube porous tissue ingrowth surface at least along the outer surface of the transcutaneous tube portion so as to form in combination with the hub porous tissue ingrowth surface a substantially continuous porous tissue ingrowth surface around the hub inlet and along the transcutaneous tube portion whereby said substantially continuous porous tissue ingrowth surface extends transcutaneously from the hub inlet at an implantation site, along the transcutaneous tube portion of adjustable length, and continues along that transcutaneous tube portion through the skin to a point above the skin surface when said hub component is implanted.
