This is called a cycle valve tube.

And this is how you make a valve.

This is actually a heart valve, which we engineered.

Does the color of the valve matter? What matters here?

Now that's a left ventricle pushing blood up through the aortic valve you can see two of the leaflets of the aortic valve working there up into the ascending aorta.

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

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.

It has a funny trilobal shape at the bottom, which contains the aortic valve.

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

People bring their own cooker, he attaches a valve and a steam pipe, and now he gives you espresso coffee.

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

Its unique cool flow valve can efficiently discharge hot and damp exhaled breath from inside the respirator, allowing easier breathing for users.

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

You're mad. I'll drive. I know I can drive.

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

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

The drive for transparency must become a drive for consistency.

He turned the wrong valve when he filled his cylinder he had 80 percent oxygen in his tank when he should have had 40.

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.

Drive slowly.

Drive carefully.

Drive safely.

Drive on.

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.

The fire disaster happened at about 10 00am and was put out at about 10 30am. It is the snifting valve inside that triggered the fire.

You drive down.

Please drive carefully.

Can you drive?

Can anyone drive?

If you drive a car in the morning and drive it back in the afternoon the ratio of charge to drive is about a minute for a minute.

Foremost, I have come to think that romantic love is a drive, a basic mating drive.

And some of these models so you take a bit of this cycle valve tube, you can put two matchsticks inside this, and you make a flexible joint.

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.

It will drive innovation.

To drive like that?

I'll drive you home.

I'll drive you home.

Jack doesn't drive fast.

I'll drive to Detroit.
