Abstract
A needle-inside, catheter placement assembly including needle and catheter units. The needle unit comprises a needle joined by a flexible line to a needle hub. The catheter unit comprises a catheter, winged catheter insertion means, flexible tubing and tube hub, wherein an area of reduced thickness on each wing of the insertion means provides improved flexibility for the wing. The needle is captured within the winged catheter insertion means when the wings are simultaneously held in a vertical position and axial and rotational alignment of the needle and catheter units are maintained by mechanically interlocked complementary means associated with the needle and lumen of the winged catheter insertion means.
