16. The guide wire handling device of claim 14 or 15, wherein the first sleeve is configured to straighten a '1' shaped tip on a distal portion of the guide wire as the tip of the guide wire enters the first sleeve when proximally feeding the guide wire into the guide wire handling device.
17. The guide wire handling device of any of claims 14-16, wherein the second sleeve has a proximal portion including an orifice with a constriction configured to capture a ball end of the guide wire and prevent the guide wire from passing completely through the second sleeve.
18. The guidewire handling device of any of claims 14-17, wherein the sterile barrier is a pleated pouch over the entire guidewire, except within or distally relative to the first sleeve, configured to fold when the pouch is inserted into an opening in a proximal portion of the first sleeve while distally feeding the guidewire out of the guidewire handling device.
19. The guidewire handling device of any of claims 14-17, wherein the sterile barrier is a separable sheath over the entire guidewire except within or distal to the first sleeve, the separable sheath being configured to separate from the guidewire while distally feeding the guidewire out of the guidewire handling device.
20. The guide wire handling device of claim 19, further comprising a first split sleeve in the distal portion of the handle, the first split sleeve being configured to discharge the detachable sheath while distally feeding the guide wire out of the wire guide wire handling device.
