An arterial cannula (64) is formed with an angled shoulder (72e) that limits the degree of insertion of cannula tip (72a) into an artery. The shoulder also forms a seal with the artery. Suture flaps (74) are formed on the cannula to attach the cannula to the patient's skin. A stylet (66) for the cannula has a stop (66b) on its exterior that prevents blood flow between the cannula and the stylet, and permits clamping (71) of the cannula with the stylet partially withdrawn. A removable anti-backflow ring (80) seals the cannula and provides a convenient initial movement limit for the stylet stop.
