A catheter having a tubular portion, a corrugated section, and a tubular tip portion. The tip portion may have side holes. A method of inserting the catheter into a selected artery by first inserting the catheter into an artery, until the tip of the catheter is near the selected artery. Then, the proximate end of the catheter is manipulated to bend a corrugated section of the catheter by forcing the tip of the catheter into the wall of the artery and pushing on the proximate end of the catheter. The proximate end of the catheter is then maneuvered to insert the tip of the catheter into the selected artery.
