Abstract
A hemodialysis catheter comprising a dual lumen tube with a bullet nose bolus at its distal end. 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 diameter D-shaped cross-section to a larger diameter circular cross-section. The bullet nose is thinner than the tube but 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.
