Abstract:
1. A medical device assembly including: an elongate tubular sleeve adapted for percutaneous implantation having axially spaced distal and proximal ends, said sleeve including a forward portion located proximate to said distal end, a rearward portion located proximate to said proximal end, and a laterally oriented shoulder surface therebetween; said forward portion having a smooth outer surface increasing from a minimum lateral dimension of D said rearward portion including a section adjacent to said shoulder surface having a porous surface of maximum lateral dimension D said tubular sleeve further having an axially extending inner surface surrounding an interior axial passageway; an elongate conduit comprising a peripheral wall having an axially extending outer surface; said conduit extending through said sleeve passageway for axial slidable movement with respect thereto; and a sealing device in said passageway peripherally contacting said conduit outer surface for preventing migration of deleterious material between said sleeve inner surface and said conduit outer surface.
