Abstract: An introducer needle assembly including a compressible section between a rigid needle and a hub. Once a vessel is entered as determined by blood entering a syringe, the compressible section of the introducer needle is occluded by compressing the compressible section with a thumb and a finger. Neither blood nor air can pass. Since the compressible section is in a flattened area it is easier to hold the needle while the syringe is unscrewed. An operator then can begin threading a guidewire down a divide which is now easier to enter because blood is not coming out of the hub thus obscuring a lumen.
