- b. a bolus tip fastened to said tube on said distal end of said tube to form a tube and tip assembly;
- c. an arterial port extending radially out of said catheter assembly in communication with said first lumen;
- d. a venous port extending radially out of said catheter assembly in a direction substantially opposite to the radial direction of said arterial port and in communication with said second lumen;
- e. said arterial and venous ports each being longitudinally elongated with respect to the length of said tube and tip assembly with a position of said venous port being positioned closer to said tip than said arterial port, and said venous port overlapping said arterial port along its length by at least a portion of the length of said arterial port.
