Abstract

A method for navigating a guide wire during a catheter procedure, the method includes changing the direction of a distal portion of the guide wire to advance past a junction in a desired path by rotating a proximal end of the guide wire a predetermined amount while the guide wire is being retracted to a point before the junction and then advancing the distal end of the guide wire past the junction through the desired path.

First claim

What is claimed is:

1. A method for navigating a guide wire during a catheter procedure, the method comprising:
advancing a guide wire through a desired path of an anatomy to a point proximate a junction;
changing the orientation of a distal end of the guide wire by retracting the guide wire in response to a first user input and
automatically rotating a proximal end of the guide wire using a catheter procedure system a predetermined amount while the guide wire is being retracted to a point before the junction in response to a second user input; and
advancing the distal end of the guide wire past the junction through the desired path.

2. A method according to claim 1 , wherein the proximal end of the guide wire is rotated a predetermined amount independent of the desired path.

3. A method according to claim 1 , wherein the guide wire is retracted a predetermined amount.

4. A method of claim 1 , wherein rotating the proximal end of the guide wire includes rotating the guide wire about a longitudinal axis of the guide wire using a guide wire rotate actuator.

5. A method of claim 4 , wherein the second user input includes activation of a touchscreen icon.

6. A method of claim 4 , wherein the second user input includes a mouse interacting with information displayed on a monitor.

7. A method according to claim 1 , wherein the steps of advancing the guide wire and rotating while retracting the guide wire are repeated until the guide wire is in the desired path.

8. A method according to claim 1 , further including:
receiving a set of parameters defining the desired path of an anatomy passing at least one junction point at a correct first branch and a side branch.

9. A method according to claim 8 , wherein rotating the guide wire includes rotating the guide wire a first amount in a first direction and then rotated rotating a second amount in the opposite direction.

10. A method according to claim 9 , further including:
advancing the guide wire through the desired path and
determining if the distal tip of the guide wire is in the desired 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.

11. A method according to claim 10 , wherein retracting the guide wire includes rotating the guide wire while retracting the distal tip of the guide wire to a position before the junction point if the distal tip of the guide wire is not in the desired path past the junction point.

12. A method according to claim 11 , further including repeating the steps of advancing the guide wire, determining if the distal tip of the guide wire is in the desired path, and retracting the guide wire until the guide wire is in the desired path, wherein the guide wire is rotated only with the first retraction of the guide wire.

13. A method according to claim 8 , wherein the proximal end of the guide wire is rotated a predetermined amount independent of the desired path.

14. A method according to claim 8 , wherein the guide wire is retracted a predetermined amount.

15. A method of claim 8 , wherein rotating the proximal end of the guide wire includes rotating the guide wire about a longitudinal axis of the guide wire using a guide wire rotate actuator.

16. A method of claim 15 , wherein the first user input includes activation of a joystick.

17. A method of claim 16 , wherein the second user input includes activation of a touchscreen icon.

18. A method of claim 16 , wherein the second user input includes a mouse interacting with information displayed on a monitor.

19. A method of claim 1 , wherein the first user input includes activation of a joystick.

20. A method according to claim 1 , wherein the guide wire is rotated while retracted in response to the first user input to retract the guide wire when the second user input has been selected.

21. A method according to claim 1 , wherein rotating the guide wire includes rotating the guide wire a first amount in a first direction and then rotating a second amount in the opposite direction.

22. A catheter procedure system comprising:
a bedside system comprising 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 control system coupled to the bedside system, the control system comprising:
a user interface including a first user input and a second user input;
at least one display;
a controller having a mode selection module programmed to:
automatically rotate a proximal end of the guide wire about a longitudinal axis of the guide wire a predetermined amount using the guide wire rotate actuator while the guide wire is being retracted and wherein the mode selection module is programmed to only automatically rotate the guide wire during the first retraction of the guide wire when the guide wire is retracted multiple times.
