1. A method of reducing the risk of clinical sequelae to catheter induced vascular injuries, the method comprising:

  • introducing a guide wire into a vascular sheath residing in a blood vessel, the guide wire having a distal end and an inflatable balloon at least 5 cm proximal of the distal end;

    proximally retracting the vascular sheath while leaving the wire in place;

    observing indicia of the presence or absence of a vascular injury caused to the blood vessel by the vascular sheath or a procedural catheter previously advanced through the vascular sheath; and

    if indicia of a vascular injury are observed;

    proximally retracting the guide wire to position the inflatable balloon adjacent the injury; and

    inflating the balloon to reduce blood flow past the injury, while leaving the guide wire in place to provide subsequent access to the injury.
