Abstract
A split tip dialysis catheter having an outer tube and an inner tube, the two tubes which can be arranged over at least a portion of their length in a coaxial configuration. The inner tube may be connected to the outer tube at a proximal bifurcation, secured at a distal end of the outer tube or both, but generally the inner tube will remain free to move relative to the outer tube to optimize functionality. In addition, the inner tube can be arranged to be removable from the catheter for replacement thereof.
