Abstract
A multiple tube catheter, such as a hemo-dialysis catheter, has first and second tubes which are attached to each other over a zone by one or more longitudinally extending wires which joins the two tubes over that zone. When a catheter is implanted in the patient, the attached zone is within the patient so that the catheter cannot be removed or advanced. When the catheter is to be removed, the longitudinally extending wire or wires are pulled proximally out of the tubes involved so that the two tubes can be separated and individually removed. A flexible separating prong within the patient and proximal of the zone holds the tubes apart to further assure that the catheter cannot be moved.
