A hemodialysis split-tip catheter comprises an elongated portion, a proximal end and a distal end defining a longitudinal axis. The proximal end attaches to a hub with suture wings assembly, which in turn connected to extension tubings. The distal end has two distal tip segments splitted from each other. The first distal tip segment has a concave shape with respect to the longitudinal axis and the second distal tip segment has an approximately J-shape with respect to first distal tip segment. Diameter of concave shape of first distal tip segment is larger than diameter of J-shape of second distal tip segment to facilitate backward bend of second distal tip segment with respect to first distal tip segment after a catheter insertion inside a blood vessel to face a blood flow direction.
