1. A medical apparatus for establishing a long-term body access channel sealed along its length and extending from a proximal location outside the skin surface, through the epidermis, and into a living body, said apparatus comprising:

  • (a) a hub component designed to be implanted subcutaneously, said hub component comprising a hub top side with a hub top side upper face that faces the skin surface when the hub component is implanted and a hub top side lower face that faces away from the skin surface, a hub sidewall extending from the hub top side to a location beyond the hub top side lower face in a direction away from the skin surface, and a hub passageway extending between a passageway inlet at the hub top side upper face and a passageway outlet at the hub sidewall, and also wherein a longitudinal axis of the hub passageway at the hub top side is oriented transversely relative to a longitudinal axis of the hub passageway at the hub sidewall;

    (b) a transcutaneous hub tube mated with the hub passageway when said hub component is implanted such that a proximal hub tube end extends above the skin surface, a transcutaneous hub tube portion extends between the skin surface and the hub passageway at least to the hub top side lower face, and the transcutaneous hub tube terminates before reaching the passageway outlet, and a transcutaneous conduit runs seriatim from outside the body, through the hub tube and said hub passageway, and into the body interior; and

    ,(c) porous tissue ingrowth surfaces along the hub top side upper face and also along the outside of at least a section of the proximal hub tube end and the transcutaneous portion of the hub tube such that porous tissue ingrowth surface extends along the hub tube from above the skin surface at least to the hub top side lower face and terminates before reaching the passageway outlet.
