You can now live without a pulse.
They began working on calves and currently have an 8-month-old calf named Abigail who has no heart. Her heart was removed and in its place the doctors inserted their new pump device. Abigail is a healthy and active young calf, however, according to any medical cardiac tests, she would appear dead.

Cohn and Frazier, after testing on 38 calves, wanted to take this new pump one step further and test it on a human patient. This is where Craig Lewis, a 55-year-old man who was dying from amyloidosis comes in. His heart had become so damaged from the disease that doctors had only given him about 12 hours to live. Lewis and his wife agreed to let the doctors try the new artificial heart pump to try and extend his life, if even for a short time. The doctors inserted the new pumps and Lewis did recover and had another month of life before the disease took other organs. His new heart however worked flawlessly.

Now that's pretty damn cool

Perhaps someday, we will be able to replace any dying/dead major organ.

That's just amazing, and a large leap for medicine, I would have never thought that this was possible someday.

So, why do they make it a smooth pump rather than a beating one? It would seem like it would make the most sense to try to replicate the heart as much as possible... is it because of added mechanical complexity or reliability?

Mechanical fatigue, I suppose. A constant rate ensures that the device will have the longest lifespan. It's comparable to aircraft in a way, which also have a short lifespan due to constant compression and decompression.

Plus, anyone who has one can say: "I'm a vampire! See, I have no pulse!"

This is amazing though, now more than ever I love to see advances in medical technology.

I wonder how well it performs, as far as being able to perform intense physical activities and stuff. I wonder if it scales up the load as a regular heart would... not that you'd need to do much cardiovascular exercise. Can't strengthen a robotic heart through exercise.

Very very interesting. I'm amazed.

I'm really curious as to how maintainence will work. Would they just put you on life support while they repair it? Will people with them have to avoid microwaves?

1 organ down, god knows how many to go. :p

I also wonder if the heart provides any feedback to the brain and if so, how the brain deals with that, or of the artificial heart emulates it.

Yeah. It seems like it also opens up a whole new set of mysteries with its use, such as what it feels like to have one and to what extent it effects one's strength.

Pretty amazing, actually... this technology should last much longer than mechanical hearts which would break down frequently

You mean pacemakers, Illumina?

IIRC, pacemakers have batteries that aren't designed to be replaced. When the battery runs out, you die.

It helps that they're usually powered by a nuclear reaction and can be replaced with mininal surgery power-wise.

Oh, hell yes! Now I can feast on all the fatty foods I want, and then become a cyborg!

In all seriousness, this is pretty awesome news.

I think my grandma's had hers replaced, actually. Also I don't see how they couldn't charge by induction somehow, if the draw on the pace maker's own power source is low enough. that might not work so well for the pump, since the pump would require a good bit of power. Not sure what a useful power source would be. Do they really use a nuclear reactor of some kind? I don't know much about that, so maybe it's not unreasonable at that scale.

Blood still pumps through other organic tubing, though. Don't risk it.

Some radioisotope thermoelectric generators have been created to power space probes (for example, the Cassini probe), some lighthouses in the former Soviet Union, and some pacemakers. The heat output of these generators diminishes with time; the heat is converted to electricity utilising the thermoelectric effect.


And now you know.
