1. A percutaneous conduit device for facilitating passage of information, energy or material to or from the interior of an animal while preventing substantial ingress of bacteria and egress of body fluids, said device comprising:

  • an elongated, generally cylindrical percutaneous conduit element having a central passageway therethrough; and

    a subcutaneous fenestrated flange mounted on the conduit element, in surrounding relationship to said passageway, the holes being dispersed throughout the flange area, being generally circular and having diameters approximately equal to the thickness of the flange and being spaced equidistant along a series of equally angularly spaCed involute spirals;

    the junction between the outer surfaces of said conduit element and said flange being rounded to provide a smoothly contoured fillet radius to facilitate and guide the proliferation of the external epidermis of an animal in which said device has been implanted in a direction down along the conduit, out, over and under the flange, through the fenestrations in the flange, and up to said passageway whereby said epidermis provides an exteriorization of the flange and a sphincter around said passageway.
