Abstract
Intravenous access is achieved by introducing a catheter over an access needle which is initially present in the catheter. A tapered dilating element is positioned over the needle and provides a transition between the needle and a larger catheter lumen. The access needle is hollow and has a port which allows blood to flash back through a lumen of the catheter so that flashback can be observed on a catheter hub or the catheter itself
