ABSTRACT:
A multi-lumen catheter for independent delivery and withdrawal of fluids having an improved leading end to minimize stasis and an improved coupling for connection to externally located infusion and withdrawal tubes. The improved leading end has an ellipsoidally shaped tip with a smooth, uninterrupted surface and, in close proximity to the tip, a port or ports evenly spaced along the length of each lumen in staggered relation between each lumen. The improved coupling is a generally L-shaped, implantable transition device bonded to a percutaneous access device. The overall conformation of the multi-lumen catheter may be either a "U-shape" or an upright "Z-shape." Externally located infusion and withdrawal tubes are in fluid connection with an epidermal end of the transition device and a multi-lumen tube fits snugly over nipples at a subcutaneous end of the transition device.
