Abstract
A catheter insertion device and method for insertion. The catheter insertion device can include a housing, a needle attached to a needle carrier, a catheter including a catheter shaft attached to a catheter hub, and a guidewire. The guidewire can include a coil tip positioned in a lumen of the needle. The method for insertion can include inserting a distal end of the needle and the catheter shaft into a blood vessel of a patient, advancing the coil tip out of the needle lumen and into the blood vessel, advancing the catheter over the guidewire, and withdrawing the guidewire and the needle from the catheter. The coil tip can include a straightened configuration and a coiled configuration. The coil tip can transition from the straightened configuration in the needle lumen to the coiled configuration in the blood vessel.
