A cuffed polyurethane catheter for long-term central venous access: a novel technique prevents early displacement.

A new method which provides immediate fixation of a cuffed central venous catheter is described. The cuffed polyurethane catheter has a detachable hub which allows the creation of a second small tunnel distal to the cuff using the wire and the vein dilator. As the catheter exits from a "pinhole," immediate fixation is assured and is independent of tissue healing.
