In fact, the term clinically insignificant residual fragment is actually a misnomer. To that end, one of our journals actually has adopted a new definition of stone-free. Let's say stone-free has three grades. Grade A, the highest grade, is there are no stones, hence the word stone-free. On a CT scale. Yeah. Based off a CT scan.

Grade B would be less than two millimeters and grade C is less than four millimeters. And you may ask, well, shouldn't it be stone free or not stone free? Again, I think this is an evolving thing going on here, but I will say that in that edge paper that I was quoting, we did notice that when we cohorted

Stones less than four millimeters versus stones greater than four millimeters, we noticed a doubling in complication rates. So the size of the stone, not only the presence of the stone, but how big of a stone you're leaving behind has even a more profound effect on what's going to happen to you as a patient.

Yeah. Or it's the end of the day, right? It's your sixth case. I'm sure those fragments are going to pass. They don't look as big as they seem.

Exactly. I'm sure just like you and probably every urologist out there that works with a trainee particularly the younger trainees, the first time they're doing ureteroscopy, they're like, I'm just curious, sir, why don't we just vacuum these pieces out? And for the past 10 years, every time they would say that, I was thinking, I know, we're working on it.

Because myself and Dr. Hleblian and Brian Eisner, We're all co-inventors of the current CVAC device. We were all at the same time period thinking of the same thing. And about 10 years ago, we all had this idea to create a vacuum or suction device. And that's kind of the genesis of one of the devices that exists out there.

And CVAC is not the only device, but that is the device that I'm most familiar with as someone that I've used. But I'd like to talk about the other devices as well, because CVAC is not the only one. But that's really how it all started about 10 years ago. And currently that device is now available in the United States. Can I talk more about the history or?
