A catheter assembly for insertion into a vessel of a patient. The catheter assembly includes an elongate hollow tubular catheter having a distal end and a proximal end. The proximal end of the catheter has a hub attached thereto. The catheter assembly further includes a needle assembly having an elongated needle with a sharpened distal end and a proximal end. The needle is disposed within the catheter prior to insertion into a patient with the distal end of the needle being distal to the distal end of the catheter. The catheter assembly also includes a safety assembly. The safety assembly has a first position for protecting the sharpened distal end of the needle, and a second position for exposing the sharpened distal end of the needle. The safety assembly normally being in the first position and being movable to the second position for insertion into the vessel of a patient.
