Abstract
A split-tip catheter for placement within the vasculature of a patient and for use in hemodialysis or other suitable procedures is disclosed. In one embodiment, the split-tip catheter includes a catheter body that defines a first lumen and a second lumen. The catheter body further comprises a split distal region, including a venous segment and an arterial segment. The venous segment includes a recess extending proximally of a nose portion; and a lateral opening in fluid communication with the first lumen. The arterial segment also includes a lateral opening, is separate from the venous segment, and is removably seatable in the recess provided by the venous segment. In one embodiment, the distal region is un-split, but includes symmetrically opposed lateral openings, as well as distal openings, in communication with the first and second lumens for providing a functional stagger for blood flow in both forward and reverse catheter flow directions.
