Abstract

A vascular access system comprises a needle (104) having a distal tip and a proximal fitting section and a dilator (114) having a solid distal section connected to a solid proximal section and an annular recess therebetween, the dilator (114) having a passageway so that the dilator (114) is coaxially positioned around the needle (104). The needle (104) has at least one opening positioned proximal to its distal tip so that, when the distal end of the needle (104) enters a blood vessel, blood enters the annular recess to show the operator that access has been achieved. Optionally, a sheath (160) having a distal tip, a proximal fitting section, and a lumen sufficient to coaxially fit over the dilator (114).
