The catheter introducer includes a removable lock head structured to be removably secured over a proximal hub portion of the catheter subsequent to insertion of the wire into the catheter, and is utilized as part of a method of inserting a catheter wherein a patient is first placed upon a grounded operating surface, the elongate wire of the catheter introducer is inserted into the catheter, current is introduced into the wire, the catheter is pushed easily through the patient's flesh as a result of contact by the energized protruding tip region of the wire with the patient's flesh, the catheter being inserted a desired distance into the patient after which the current is removed from the wire and the catheter introducer is removed from the catheter to allow normal use of the catheter.
