Claim:
1. A method for inserting a catheter into a patient, the method comprising: providing a catheter insertion device including an outer housing, a tubular access needle attached to a needle carrier that is slidable with respect to the outer housing, a tubular catheter having a hub detachably attached at a distal end of the outer housing and positioned coaxially around the tubular access needle, an actuator mechanism, and a safety guidewire having a tip comprising a preformed coil and being sized and configured to be advanced through the tubular access needle; inserting a distal end of the tubular access needle into the patient; actuating the actuator mechanism to advance the safety guidewire out through the tubular access needle in a distal direction so that the preformed coil assumes a coiled configuration; advancing a distal end of the tubular catheter over the safety guidewire into the patient; and actuating the actuator mechanism to withdraw the safety guidewire and the tubular access needle through the tubular catheter in a proximal direction;
