Claim:
1. A transcutaneous component of a medical access assembly that comprises separate, connectable transcutaneous and subcutaneous components which, respectively, define transcutaneous and subcutaneous channels that, in combination, establish a complete long-term body access channel extending from a proximal location outside the skin, through the transcutaneous and subcutaneous components, to a distal internal location in a living body, the transcutaneous and subcutaneous components adapted for being subcutaneously connected at a subcutaneous connection location to join the respective transcutaneous and subcutaneous channels, wherein the transcutaneous component comprises a unibody construction that includes: (a) a hub having at least first and second sides, and with integral skirt and tube members disposed along the first side of the hub, whereby the tube projects transcutaneously from an interior region of the hub, through the first side of the hub, to above the skin surface when the hub is implanted, and the skirt covers and seals the juncture between the first side of the hub and the tube; (b) a hub passageway through the hub interior region providing a connection between the interior of the tube and an outlet connector at the second side of the hub, whereby a transcutaneous channel is defined that runs seriatim from outside the body, through the tube, through the hub passageway, to the outlet connector; and, (c) porous tissue ingrowth material that covers at least enough of the skirt and tube members to provide a substantially continuous porous tissue ingrowth surface between the skirt and the skin surface when the hub is implanted; and further comprising: a right-angle conduit member connected to the end of the tube that projects above the skin surface; an extension tube with proximal and distal extension tube ends wherein the distal extension tube end is connected to the right-angle conduit member, and the proximal extension tube end is connected to a luer assembly; and a catheter tube that runs at least through the interior of an extended transcutaneous channel defined by the components of the transcutaneous component assembly from the luer assembly at a proximal end of the extended transcutaneous channel to the outlet connector at a distal end of the extended transcutaneous channel.
