The utility model relates to a needle assembly and a guide wire auxiliary catheter system. The needle assembly includes: a needle hub; a plug having an outer surface having a first portion including a vent hole providing a fluid passage between the outer surface of the plug and an inner surface of the interior interconnecting the interior and the proximal opening of the needle hub; the proximal end of the guide needle is fixed to the proximal end of the needle hub via the aperture, the distal end of the guide needle extends beyond the distal end of the needle hub, the proximal opening of the guide needle is accessible at the proximal end of the needle hub such that the guide wire can pass through the lumen of the guide needle via the proximal opening of the guide needle, and the distal end of the guide needle extends beyond the distal end of the needle hub. An introducer needle having a distal opening and extending through the distal opening of the introducer needle, the introducer needle including an incisio
