CATHETER INTRODUCER ASSEMBLY ABSTRACT OF THE DISCLOSURE A catheter introducer assembly is disclosed. The assembly is made up of a winged catheter introducer having a catheter, an intermediate member attached tothe catheter and a flexible tube attached to the intermediate member. Disposed axially within the catheter is a sharp needle. The needle is secured to a stylet which in turn is connected to a bead. The bead is slidable in the tube. Secured to theoutside of the tube is a hard tubular section. A retractor is slidably mounted to the outside of the tube. The retractor confines the bead such that when the retractor slides along the outside of the tube, the bead slides along the inside of the tube. The retractor is provided with ribs shaped such that the retractor can be moved along the tube in one direction only. When the needle is retracted, its sharp tip is aligned with the hard tubular section. The needle is thus secured within the tubular section.
