Okay, looks good.

I don't know, something screwed the whole system up.

Oops, where are the videos?

So what we are currently doing is we look at the magnetic navigation system and I brought

a few videos with me.

Hopefully it will start.

Yes.

Here you see one of these typical systems.

You see here the C arm device and the magnets and here you see the user interface with the

two views from two different directions.

If you take a closer look at it you can also see that doctors can draw in some lines and

define a 3D orientation vector of the magnetic field that is generated by these two magnets.

And as I said this MIST system is used for catheter navigation.

That's the major application of that.

And let's have a look at the catheter, how it is moved in the magnetic field.

So you do not operate the thing by the mechanical device outside of the human body.

The tip here is just moved by changing the magnetic field.

There is a little magnet in the tip and with its interaction with the magnetic field the

whole thing is moving.

So one magnet rotates, that's a prototype installation, it's already five or six years

old and here you see how you can change the orientation of the catheter.

And that's very important for interventional procedures.

I motivated this last week already if you want to go with a catheter into the cerebral

vessel system for instance that is highly complicated.

It takes a while to get the right track and with the magnetic field you can adjust the

orientation of the catheter and maybe it's much easier to get to the point where you

want to coil for instance an aneurysm.

And I also told you that there are a few experts or many experts saying you know we don't like

this technology and the reason for that is that you know less experienced doctors can

do much harder procedures actually.

Sometimes it's good, sometimes it's not that good.

Another application I want to show to you is shown here.

We have seen that aneurysms can be coiled last week.

That means you can fill up aneurysms with some platin wires and then the whole thing

is filled up with metal and no blood can go inside anymore.

This procedure works only if the aneurysm has a so-called neck.

Let me just reconsider this.

If we have a neck here and the coils are kept inside the aneurysm and they cannot fall out

because you have here this narrowing area here, the neck.

And if someone has a sagittal aneurysm, that's how it is called, and you have no neck, you

can put in coils here but they will not be kept inside the aneurysm but they might fall

outside and occlude the vessel.

So in this situation, surgery is required.

So you have to open up the skull and you have to clip this aneurysm such that it's closed.

And that's of course not a minimally invasive procedure, that's quite an invasive procedure.

You have to open the skull and you destroy brain tissue and so the patient usually has

a hard time to recover from this type of procedure.

And the idea was now with the magnets, why don't we have a magnetic glue?

That was the idea.

Oops, magnetic glue.
