A vascular access catheter having a curved tip. Preferably, the curved tip is formed into a substantially pig-tail shape. Where the catheter is of the double lumen variety, the terminus of the draw lumen is at the end of the curved tip, and thus is shielded from direct contact with a side wall of the blood vessel into which the catheter is inserted. This configuration lessens risks associated with prior art vascular access catheters, including occlusion of the catheter and damage to the vein wall. |
