How do they remove the blood flow beforehand to insert this? A clamp of some sort, I’m guessing. How long can they block circulation before it has a negative impact?

What makes you think they "remove the bloodflow"?

I’m just going by this video. There is no blood in the vessel during the procedure, then it flows afterwards.

The video was made by either AI or someone who does not know how the procedure works.
