A split-tip catheter for placement within the vasculature of a patient and for use in hemodialysis or other suitable procedures. In one embodiment, the split-tip catheter includes a catheter body defining a first lumen and a second lumen, and a split distal region extending from a distal end of the catheter body. The split distal region includes an arterial segment defined by an outer wall enclosing an arterial segment lumen, the arterial segment lumen in fluid communication with the catheter body first lumen, and a venous segment defined by an outer wall enclosing a venous segment lumen, the venous segment lumen in fluid communication with the catheter body second lumen, the venous segment outer wall extending from the catheter body distal end to a distal nose portion. The distal nose portion may taper distally from a first outer perimeter to a second outer perimeter smaller than the first outer perimeter.
