Abstract

A supra-aortic vessel access robotic control system includes a guidewire hub configured to adjust each of an axial position and a rotational position of a guidewire; a guide catheter hub configured to adjust a guide catheter in an axial direction; and a procedure catheter hub configured to adjust each of an axial position and a rotational position of a procedure catheter, and also to laterally deflect a distal deflection zone of the procedure catheter.

First claim

What is claimed is:

1. A supra-aortic vessel access robotic control system comprising:
a guidewire hub being configured to adjust an axial position of a guidewire and a rotational position of the guidewire;
a guide catheter hub being configured to adjust a guide catheter in an axial direction;
a second catheter hub being configured to adjust an axial position of a second catheter and a rotational position of the second catheter; and
a drive magnet, the drive magnet being axially movable and positioned within a support table, wherein the drive magnet is separated from the guidewire hub, the guide catheter hub, and the second catheter hub by a sterile barrier;
wherein one of the guidewire hub, the guide catheter hub, and the second catheter hub comprises a driven magnet, wherein the drive magnet is coupled to the driven magnet so that axial movement of the drive magnet causes axial movement of the driven magnet, wherein the drive magnet is outside of a sterile field, wherein the driven magnet is within the sterile field.

2. A control system as in claim 1 , wherein the second catheter is an aspiration catheter.

3. A control system as in claim 1 , wherein the second catheter is an embolic deployment catheter.

4. A control system as in claim 1 , wherein the second catheter is configured to deploy embolic coils.

5. A control system as in claim 1 , wherein the second catheter is a stent deployment catheter.

6. A control system as in claim 1 , wherein the second catheter is configured to deploy a stentriever.

7. A control system as in claim 1 , wherein the second catheter is a flow diverter deployment catheter.

8. A control system as in claim 1 , wherein the second catheter is a diagnostic angiographic catheter.

9. A control system as in claim 1 , wherein the guidewire hub comprises the driven magnet.

10. A control system as in claim 9 , wherein the guidewire hub further comprises a housing, wherein the driven magnet is coupled to the housing.

11. A control system as in claim 9 , wherein:
the guidewire hub further comprises a first housing;
the driven magnet is a first driven magnet coupled to the first housing;
the guide catheter hub further comprises a second housing and a second driven magnet coupled to the second housing; and
the second catheter hub further comprises a third housing and a third driven magnet coupled to the third housing.

12. A control system as in claim 1 , wherein the barrier comprises a polymer membrane.

13. A control system as in claim 1 , further comprising a control console located remotely from the support table.

14. A control system as in claim 13 , wherein the position of the driven magnet is movable in response to manipulation of a guidewire drive control on the console.

15. A control system as in claim 14 , further comprising a processor for controlling the position of the driven magnet, and the processor is in wired communication with the control console.

16. A control system as in claim 14 , further comprising a processor for controlling the position of the driven magnet, and the processor is in wireless communication with the control console.

17. A control system as in claim 1 , wherein the driven magnet will remain engaged with the drive magnet until an applied force reaches a disruption force threshold above which the driven magnet will become decoupled from the drive magnet.

18. A control system as in claim 17 , wherein the disruption force threshold is at least about 300 grams.

19. A control system as in claim 17 , further comprising a sensor configured to measure the applied force between the driven magnet and the drive magnet.

20. A control system as in claim 19 , further comprising a processor configured to compare an applied force to the disruption force threshold.

21. A control system as in claim 20 , wherein the processor is configured to adjust a rate of movement of the drive magnet when the applied force reaches a preset value below the disruption force threshold.

22. A control system as in claim 21 , wherein the processor is configured to halt movement of the drive magnet when the applied force reaches a preset value below the disruption force threshold.

23. A control system as in claim 19 , wherein the sensor comprises a strain gauge.

24. A control system as in claim 1 , wherein the second catheter hub is further configured to laterally deflect a distal deflection zone of the second catheter.

25. A control system as in claim 1 , wherein the guidewire hub, guide catheter hub, and second catheter hub are axially movable along the sterile barrier.
