> first implant of an artificial heart that can beat for up to five years One: I don't think this is the first. Two: the artificial hearts I've heard of don't actually beat ; it's more of a constant flow.

Reading their website ( http://www.carmatsa.com/index.php?option=com_flexicontent&vi... ), as near as I can tell, they're basically claiming to be "closest yet" to a real heart, including "auto-regulation", which I think means they're saying it can beat faster or slower as you need more or less bloodflow. The scariest thing is that they also boast a significant increase in battery life ... to 12 hours. Jesus, I get a…

Shows how amazing evolution is at "designing" complex efficient systems. Our hearts beat for 70-100+ years without a charge.

Don't know about you, but my heart needs a charge every six hours and it goes in hibernation mode every 12 hours.

Can I upgrade to yours? :-)

Perhaps this title was initially Reuters' error? Their current headline reads, " France's Carmat implants its first artificial heart in human ". This sounds like a big first step for this company, though as other commenters have noted, this is certainly not the first artificial heart implanted in a human. Certainly, if there were a viable long-term replacement that didn't require people to become brain dead so that o…

I suggest checking out the short video "Flatline" on Vimeo. I can't link to it from my phone but it's worth a watch.

Really worth a watch: http://vimeo.com/46912551

I was incredibly excited by this, but the article mentions that another company, SynCardia already has a thousand of these devices deployed into Production.

It seems it is the first device to really deserve the term "artificial heart". Before, it was blood pump.

If your heart stops beating for 12 hours, maybe you need to talk to your doctor.

Pretty amazing that it was a result of a lucky mutation. I wonder what happened to the millions (billions?) of organisms that couldn't maintain a steady heartbeat?

I'm pretty sure you have to eat every so often for your heart to keep on working...

They had their lunch eaten by the heartbeaters, and when we were done eating their lunch, we ate them :)

Why does it need to pump or emulate a real heart? Could one not create the same in a much smaller form factor with lower power usage?

Are you asking if pulsation flow is needed? Other systems depend on the pulsation nature of our circulatory system. I'm no expert, but off the top of my head CSF flow and bowel peristalsis depend on pulsation blood flow to a degree (or so I was taught, ages ago). I'm sure there are others who are more knowledgeable here though.
