The most difficult part of the whole procedure was then removing this endoscope, this black endoscope here without moving the guide wire. So we had to do this inch by inch with several people holding the other end of the guide wire, and here is Frank consulting with Thomas, who's behind Shanthi looking at the ultrasound all this time to let us know whether the guide wire is moving. So, after that is over and we're all covered with sweat, after that procedure, we then insert the second catheter which is the same idea - it's a smaller version of the first catheter. It's very long, about two meters long, and it has a small balloon at the end. Then after this catheter is in place and inflated, we then can insert the second endoscope, which is much smaller than that first one. And you can see here Frank is actually looking through the eye piece of the second endoscope.

Now this is allowing him to look through the vagina. We're now past the opening of the vagina. And the ultrasound image from this allows us to see that the endoscope, which is here, is now in the cervix. You see this white line here? And then it's got kind of a dark line in the middle of it. That dark line is water, because we filled one of the channels of the endoscope with water, and on ultrasound, water looks black. So that's how we know that this is the endoscope. We know that this is cervix here.
