Abstract
A catheter comprising a dual lumen tube with a bolus at its distal end having a bullet nose. A venous port is formed in one side of the bolus adjacent the bullet nose of the bolus. An arterial port is formed in the bolus circumferentially displaced 180.degree. around the catheter from the venous port. The bolus contains a venous passage which transitions from a smaller two-thirds moon shaped cross-section to a larger circular cross-section. The arterial passage has a crescent-moon shaped cross-section. The bullet nose is not as thick as the tube and is inclined on an angle to the axis of the tube so that a portion of its outer periphery is substantially tangent to a hypothetical cylinder containing the trailing edge of the venous port.
