SLIDE 25

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.
