Abstract
A hemodialysis catheter is provided which includes a catheter body having a proximal and a distal end and defining at least one lumen. The at least one lumen includes a distal opening and a side opening formed through a sidewall of the catheter body. The side opening communicates with the at least one lumen, and includes guiding structure positioned adjacent a distal side of the side opening configured to smoothly redirect blood flow into the at least one lumen. The guiding structure may be defined by a raised wall, or in the alternative, an angled distal wall of the side opening.
