Abstract
A cannula/catheter is provided which is suitable for long term or semi-permanent through-the-skin function while permitting tissue ingrowth which promotes healing and seals out sources of infection. The catheter is provided with a sheath formed of an elastomeric coating which is glow discharge treated, folded back on itself to form a cuff and surgically implanted and anchored in place. The cuff portion of the sheath is advanced outwardly by the growth of skin adherent to its periphery while the catheter is maintained in its original position.
