A vascular catheter with a circular external diameter, a circular lumen contained within, and an inflatable balloon that overlies a trough in the catheter body such that when the balloon is deflated, the balloon does not protrude beyond the outer circumference of the catheter shaft. The wall of the catheter shaft is thicker along one side than along the remainder of the circumference of the catheter shaft to permit an inflation lumen to be disposed within the thick wall section without increasing the outer diameter of the remaining portion of the circumference. The inflatable balloon is further disposed to maintain the circular lumen of the catheter in the center of flow of the blood vessel in which it is used, maintaining optimal flow. The combination of the circular lumen, circular outer diameter, and recessed balloon trough produces improved hemodynamic flow characteristics within the cannula over existing balloon cannula designs, minimizing flow-related injuries that might cause embolization or vascular dissection.
