摘要：
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 that defines a distal portion of the first lumen and an arterial segment that defines a distal portion of the second lumen. 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 is separate from the venous segment and is removably seatable in the recess provided by the venous segment such that it “nests” therein. The arterial segment also includes a lateral opening in fluid communication with the second lumen.
