description Disclosed is a multi-lumen catheter having a distal end catheter tip configured to improve fluid flow into and out from the catheter tip while reducing undesired recirculation during hemodialysis treatment of a patient. A first lumen and a second lumen each extends from the catheter proximal end to the catheter distal end, the first lumen and the second lumen being parallel to each other. A septum having a first side and a second side separates the first lumen from the second lumen. Some embodiments of the catheter tip include a beveled shape region, having a first lumen orifice, a second lumen orifice, and a septum top surface. Within the beveled shape region, at least a portion of the septum first side and at least a portion of the septum top surface form a first eave over the first lumen and at least a portion of the septum second side and at least a portion of the septum top surface form a second eave over the second lumen.
