An arterial catheter includes an elongate tube having a sidewall with an inside surface and an outside diameter. The catheter has a proximal end, an open distal end with a tip portion, and a hollow bore with an inside diameter. There is a hub attached to the proximal end of the catheter that is in fluid communication with the hollow bore. The inside surface of the hollow bore has a plurality of inward projections disposed longitudinally from the proximal end to the distal end. The tip portion has at least one hole through the sidewall into the bore. The catheter sidewall outside diameter is tapered distally from the hole to the open distal end and the inward projections on the inside surface of the bore are substantially diminished in the tip portion.
