ABSTRACT:
Disclosed is an article for use as a component part of a catheter system wherein a proximal section is exteriorized above the skin for connection to a liquid drug source, the article comprising a flexible sleeve having an advancement tip at its distal end to facilitate advancement of the sleeve into a passage beneath the skin created by tunneling the catheter subcutaneously to an exit site where the proximal end is exteriorized, the advancement tip having a generally bullet-shaped leading end and a base section having an outer diameter greater than the outer diameter of the sleeve, the advancement tip having a channel extending therethrough for receiving the catheter for passage through the sleeve; an adapter for placing the proximal end of the catheter in liquid communication with the drug source, the adapter having a channel extending longitudinally between the adapter ends, an opening at the distal end of the adapter communicating with the adapter channel and through which the proximal end of the catheter can be inserted, the proximal end of the catheter is releasably secured within the opening and in liquid communication with the adapter channel, and the proximal end of the sleeve is permanently attached to the distal end of the adapter with the sleeve surrounding the opening in the adapter so that a catheter extending through the sleeve may be introduced into the adapter opening to receive liquid drug passing therethrough.
