Abstract:
The present invention is directed to a vascular access device for introducing a catheter in a blood vessel using a guide advancing mechanism. The device generally comprises a housing, an introducer needle, a catheter, a guide wire and an actuating means. The introducer needle of the vascular access device is used to penetrate the blood vessel. The actuating means is then initiated and the guide wire is steadily propelled into the blood vessel. Once the guide wire is in place, the catheter, which is concentrically placed over the introducer needle and guide wire, is uncoupled from the vascular access device and guided into the blood vessel by the guide wire.
