System and method for navigating a guide wire
A catheter procedure system includes a bedside system having a guide wire, a guide wire advance/retract actuator coupled to the guide wire and a guide wire rotate actuator coupled to the guide wire and a workstation coupled to the bedside system. The workstation includes a user interface, at least one display and a controller coupled to the bedside system, the user interface and the at least one display. The controller is programmed to advance the guide wire through a path using the guide wire advance/retract actuator, determine if the guide wire is in a desired path based at least on at least one image of a region of interest, rotate the guide wire using the guide wire rotate actuator if the guide wire is not in the desired path, wherein the guide wire is rotated a predetermined amount, and retract the guide wire using the guide wire advance/retract actuator. The steps of advancing the guide wire and retracting and rotating the guide wire using guide wire advance/retract actuator and the guide wire rotate actuator are repeated until the guide wire is in the desired path. The guide wire is advanced to a desired position using the guide wire advance/retract actuator.

determining if a distal tip of the guide wire is in the predetermined path based at least on at least one image of a region of interest past the junction point using a controller of the catheter procedure system;
retracting the guide wire using the catheter procedure system to a position before the junction point if the distal tip of the guide wire is not in the predetermined path past the junction point;
rotating the guide wire about a longitudinal axis of the guide wire while the guide wire is being retracted using the catheter procedure system if the guide wire is not in the predetermined path, wherein the guide wire is rotated a predetermined amount;
repeating the steps of advancing the guide wire, determining if the distal tip of the guide wire is in the predetermined path, and retracting the guide wire using the catheter procedure system until the guide wire is in the predetermined path, wherein when the guide wire is rotated only with the first retraction of the guide wire.
7. A method according to claim 6 , wherein retracting the guide wire occurs while the guide wire is rotated.
8. A method according to claim 6 , wherein the guide wire is retracted a predetermined amount.
9. A method according to claim 6 , wherein the at least one image is a fluoroscopic image.
