1. A catheter assembly, comprising:
- a catheter body including;
an outer wall;
a first lumen and a second lumen separated by a septum; and
a distal tip region including;
a terminal catheter portion;
a nose portion distal of the terminal catheter portion;
a venous lateral opening in fluid communication with the first lumen; and
an arterial lateral opening in fluid communication with the second lumen, the venous and arterial lateral openings positioned un-staggered with respect to one another, each having a proximal end defined through the catheter outer wall in the terminal catheter portion, the defined proximal end openings comprising a shape that is symmetrical with respect to a plane through a central axis of the catheter body perpendicular to the septum.

Abstract
A catheter assembly for use in accessing a vasculature of a patient during renal replacement or other therapies is disclosed. In one embodiment, the catheter assembly includes a catheter body that defines first and second lumens. The catheter body defines a distal tip region that includes a venous lateral opening that is in fluid communication with the first lumen and an arterial lateral opening that is in fluid communication with the second lumen.

23. A catheter assembly, comprising:
-
a catheter body defining a first lumen and a second lumen separated by a septum, the catheter body including a distal tip region, the distal tip region including; a terminal catheter portion; a nose portion distal of the terminal catheter portion; a venous lateral opening in fluid communication with the first lumen; and an arterial lateral opening in fluid communication with the second lumen, the venous and arterial lateral openings positioned un-staggered with respect to one another, each of the venous and arterial lateral openings having a proximal end defined through a catheter outer wall in the terminal catheter portion; wherein the septum extends to a distal end of the nose portion; wherein when inserted into a vasculature of a patient; in a first operational configuration state blood is aspirated from the vasculature via the arterial lateral opening and blood is infused into the vasculature via the venous distal opening; and in a second operational configuration state blood is aspirated from the vasculature via the venous lateral opening and blood is infused into the vasculature via the arterial distal opening.
