A catheter guide wire introducing device for aspiration of a body part and insertion of a guide wire into the body part is provided. The catheter guide wire introducing device includes a flexible bulb. A fitting is located on the first end of the bulb. The fitting includes an internal chamber and first and second axially aligned passageways in fluid communication with the chamber. A third passageway is provided in fluid communication between the chamber and the interior of the cavity of the flexible bulb. An introducer needle having first and second ends and a lumen is provided. The first end of the needle is connected to the fitting such that the first passageway is in fluid communication with the lumen. A conduit having first and second ends and a passageway extending therethrough is also provided. The conduit is axially aligned with the introducer needle. The first end of the conduit is connected to the fitting such that the conduit passageway is in fluid communication with the second passageway. The conduit and the introducer needle are axially aligned. A guide wire penetrable seal assembly is connected to the second end of the conduit in fluid communication with the conduit passageway for preventing the passage of fluid from within the conduit and air from outside the conduit therethrough and for introduction of the guide wire into the conduit.
