Abstract
A method of reducing the risk of clinical sequelae to catheter induced vascular injuries may include introducing a guide wire into a vascular sheath residing in a blood vessel, proximally retracting the vascular sheath while leaving the wire in place, and 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. If indicia of a vascular injury are observed, the method may further involve 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. The inflatable balloon can be inflated and deflated through a valve positioned at the proximal end of the guide wire.
