My carotid artery had ruptured.

Fortunately, the shark bite didn't hit any major arteries.

There's a big clot in the middle of the artery.

Here you have a retina.

In other words, we're not literally replacing the components of the retina.

And on the right you actually see a carotid artery that was engineered.

We've just abstracted what the retina's doing with a set of equations.

The image projected in the retina is inverted.

This is actually the artery that goes from your neck to your brain.

The retina chip extracts four different kinds of information.

So you have an image, a retina, and a brain.

A means to determine if there's a complete blockage of a coronary artery.

And then the transducer then makes the output cells send the code on up to the brain, and the result is a retinal prosthetic that can produce normal retinal output.

But when it's moving back and forth, the retina picks up these changes.

And before I left the hospital, after a year of being hospitalized, I had seven ruptures of my carotid artery.

Blood is then pumped from the right ventricle through the pulmonary valve and into the pulmonary trunk of the pulmonary artery.

It's your major artery, and it was severed, so my blood was gurgling out of my mouth.

Can we reconstruct what the retina was seeing from the responses from the firing patterns?

The retina chip that we designed sits behind this lens here.

We're putting in a copper stent, and this copper stent erodes the artery and causes heart attacks.

Avenida Presidente Julio Argentino Roca (also known as Diagonal Sur ), is a main artery in the Monserrat quarter of Buenos Aires, Argentina.

Well, with the pig, at the baseline, before we blocked the pig's artery to simulate a heart attack, that was the signal.

New onset angina is also considered unstable angina, since it suggests a new problem in a coronary artery.

So what we did is we took a moment in time from these recordings and asked, what was the retina seeing at that moment?

What you notice here is that these snapshots taken from the output of the retina chip are very sparse, right?

Well, he kept the balloon filled to block the artery, to simulate a blockage, which is what a heart attack is.

When this first came out, it was just a really exciting thing, the idea that you even make a blind retina respond at all.

Hughes was wearing a helmet, but the ball made contact with an unprotected area, damaging his vertebral artery which caused bleeding in the brain.

This experience taught me to empathize more with my patients, and especially those with retinal diseases.

But sometime ago, through the help of an opthamologist colleague of mine, Carmen Puliafito, who developed a laser scanner of the retina, I found out the the following.

So on the left is the encoder alone, and on the right is from an actual blind retina, so the encoder and the transducer.

Heart disease, stroke, diabetes, spinal cord injury, muscular dystrophy, retinal eye diseases are any of these conditions relevant, personally, to you?

Light enters, hits the back of the retina, and is circulated, most of which is streamed to the very back of the brain, at the primary visual cortex.

And I'm going to show you a system that we designed to model the retina, which is a piece of brain that lines the inside of your eyeball.

Then what happens is the retinal circuitry, the middle part, goes to work on it, and what it does is it performs operations on it, it extracts information from it, and it converts that information into a code.

So when you look at something, like this image of this baby's face, it goes into your eye and it lands on your retina, on the front end cells here, the photoreceptors.

And the chip I'm going to show you a video that the silicon retina put out of its output when it was looking at Kareem Zaghloul, who's the student who designed this chip.

So what it's doing is, it's replacing the retinal circuitry, really the guts of the retinal circuitry, with a set of equations, a set of equations that we can implement on a chip. So it's just math.

Renovascular hypertension (or renal hypertension ) is a syndrome which consists of high blood pressure caused by the kidneys hormonal response to narrowing of the arteries supplying the kidneys (renal artery stenosis).

Central Intelligence Agency.

The SBS hypothesis attributed the triad of symptoms to the physical rupture of blood vessels on the brain s surface and in the retina, and the tearing of nerve fibers within the brain.

51 Days 52 Days Developing retina, nose and fingers The fetus' continual movement in the womb is necessary for muscular and skeletal growth.

Then I started thinking, would it be possible to hook up a heart lung bypass machine and have a surgery where it was a tube going into my artery, and then appear to not breathe while they were oxygenating my blood?
