Abstract

A method of priming an interventional device assembly includes providing the interventional device assembly, the interventional device assembly including a first interventional device and a second interventional device, the second interventional device being positioned within the first interventional device. The method further includes reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device while flushing a lumen between the first interventional device and the second interventional device with fluid to remove microbubbles from the lumen.

First claim

What is claimed is:

1. A method of priming an interventional device assembly, comprising:
providing the interventional device assembly, the interventional device assembly comprising a first interventional device and a second interventional device, the second interventional device being positioned within the first interventional device; and
reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device while flushing a lumen between the first interventional device and the second interventional device with fluid to remove microbubbles from the lumen.

2. The method of claim 1 , wherein reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device comprises reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device in response to a control signal.

3. The method of claim 1 , wherein reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device comprises reciprocally moving at least one of a first robotic drive coupled to the first interventional device and a second robotic drive coupled to the second interventional device relative to the other of the first robotic drive and the second robotic drive.

4. The method of claim 1 , wherein reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device comprises axially reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device.

5. The method of claim 4 , wherein reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device further comprises rotationally reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device.

6. The method of claim 4 , wherein axially reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device comprises axially reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device over a stroke length between about 10 mm and about 250 mm.

7. The method of claim 6 , wherein axially reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device comprises axially reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device over a stroke length between about 25 mm and about 125 mm.

8. The method of claim 4 , wherein axially reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device comprises axially reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device over a stroke length greater than 20 mm.

9. The method of claim 4 , wherein axially reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device comprises axially reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device at a reciprocation frequency of no more than about 5 Hz.

10. The method of claim 9 , wherein the reciprocation frequency is no more than about 1 Hz.

11. The method of claim 1 , wherein reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device comprises rotationally reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device.

12. The method of claim 1 , wherein reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device comprises reciprocally moving both the first interventional device and the second interventional device relative to one another.

13. The method of claim 1 , wherein reciprocally moving at least one of the first interventional device and the second interventional device relative to the other of the first interventional device and the second interventional device is performed by a robotic drive table.

14. The method of claim 1 , wherein the first interventional device is a first catheter and the second interventional device is a second catheter.

15. The method of claim 1 , wherein the first interventional device is a catheter and the second interventional device is a guidewire.

16. A method of priming a multi catheter assembly, comprising:
providing the multi catheter assembly, the multi catheter assembly comprising a guidewire, an access catheter, a procedure catheter, and a guide catheter arranged in a concentric catheter stack, wherein the guidewire is positioned within a lumen of the access catheter, the access catheter is positioned within a lumen of the procedure catheter, and the procedure catheter is positioned within a lumen of the guide catheter; and
flushing the guide catheter with saline while reciprocally moving at least one of the guide catheter and the procedure catheter relative to the other of the guide catheter and the procedure catheter.

17. The method of claim 16 , wherein flushing the guide catheter with saline while reciprocally moving at least one of the guide catheter and the procedure catheter relative to the other of the guide catheter and the procedure catheter comprises reciprocally moving at least one of the guide catheter and the procedure catheter relative to the other of the guide catheter and the procedure catheter in response to a control signal.

18. The method of claim 16 , wherein flushing the guide catheter with saline while reciprocally moving at least one of the guide catheter and the procedure catheter relative to the other of the guide catheter and the procedure catheter comprises reciprocally moving at least one of a first robotic drive coupled to the guide catheter and a second robotic drive coupled to the procedure catheter
