1. An implantable device for providing a circumferential bacterial seal and sutureless tissue fixation to a percutaneous conduit of known outside diameter, comprising a distensible elastomeric sleeve having a relaxed inside diameter smaller than said known diameter, and having sufficient resiliency to enable forcible expansion of the inside diameter so the sleeve can be moved along the conduit into an implanted intracorporeal position beneath a skin exit site at any desired longitudinal position along the conduit, the resiliency of the sleeve providing a restoring force sufficient to place the sleeve in frictional gripping contact with the conduit at said position when the expanding force is removed, the sleeve being formed of a tissue-compatible material and having an outer surface which promotes tissue ingrowth.
