And the fact that pig heart valves have lots of these on them is the reason that you can't transplant a pig heart valve into a person easily.

This is actually a heart valve, which we engineered.

And the way you engineer this heart valve is the same strategy.

And you can go inside the heart itself and repair the valves from the inside.

This is actually a heart valve that we've engineered, and you can see here, we have the structure of the heart valve and we've seeded that with cells, and then we exercise it.

He can go inside, push inside of the heart, and really feel how the valves are moving.

An iPatch, iRhythm, for atrial fibrillation.

We can also know who's likely to get atrial fibrillation.

And what happens is this can be implanted into a human heart without open heart surgery.

So you see the leaflets opening and closing of this heart valve that's currently being used experimentally to try to get it to further studies.

We take the scaffold, we seed it with cells, and you can now see here, the valve leaflets opening and closing.

Likewise, if you have the artificial valve option, you're committed to antibiotic therapy whenever you have any intrusive medical treatment at all.

Even trips to the dentist require that you take antibiotics, in case you get an internal infection on the valve.

So this is actually a Dutch company, so I called them up, and I asked, Can I borrow a heart valve from you?

So one of the pioneers, for example, is Dr. Anthony Atala, and he has been working on layering cells to create body parts bladders, valves, kidneys.

So, the most beautiful thing I found at least what I think is the most beautiful in the book, is this heart valve.

So he suffered from essential tremor for many years.

Some just had the DT's.

And once it's in the right spot, they remove the outer shell, and the heart valve, well, it gets this shape and at that moment it starts beating, instantly.

He's probably hiding out somewhere, scared and shaky.

Vibrations...

The low tech bit is that it's literally a pig's heart valve mounted in the high tech bit, which is a memory metal casing.

Great and then I didn't hear from them for weeks, so I called, and I asked, What's going on with the heart valve?

But I mentioned that the film is also technological.

Vibraphone

Zuzu's petals.

Six weeks, these folds are now beginning with the papilla on the inside of the heart actually being able to pull down each one of those valves in your heart until you get a mature heart and then basically the development of the entire human body.

I was visiting a cousin of mine in an old age home, and I spied a very shaky old man making his way across the room on a walker.

Jost was shaking. Maybe I was too.

You're shivering.

And we'll shiver

(releases air valve)

But I said we can't get rid of it, because all the people who tried to transplant heart valves found out you can't get rid of that immunity.

For days, I struggled to keep alive and I shivered with loneliness in a back room on the fourth floor of nowhere.

You poor thing. You're trembling all over.

Am I shaking?

The petals are floating on the water.

The stage was sprinkled with flower petals.

Paste it!

Now, we'll paste this together here.

'Then the petals fell'

Flutter

Your hands are trembling.

Zuzu's petals. Zuzu...

opens its petals to enlightenment.
