Yep. Constant irrigation, constant aspiration or suction. And then if you want to turn it on to high power irrigation, you've got that spray that comes out. And then the high power suction where you really turn on the vacuum. So there's two levels to it, the aspiration and irrigation.

Well, the problem is the current retroscopes that are out there, the working channel is a channel that's shared for irrigation fluid coming in, the basket or the laser that you're using, some working device. And then if you want to do what you're describing, then you'd have to... temporarily stop the irrigation and then pull back, right? And you think that would work.
