Abstract

A hemodialysis catheter for use within a vein of a patient includes a catheter body having a proximal end when positioned within and relative to the vein. The catheter body defines an arterial lumen and a venous lumen. The catheter body is shaped with a curved tip which has a distal end. The venous lumen is truncated at a location between the proximal end of the catheter body and the distal end of the curved tip. The truncated location of the venous lumen defines an out-flow opening. The distal end of the curved tip defines an in-flow opening which corresponds to the arterial lumen. The vein has a blood flow direction and the in-flow opening faces the blood flow direction.
