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 others could get a heart transplant, that would be a major boon to humanity. And a 5-year bridge, if the hopes for the lifetime of this device pan out, would be a major forward step.
I was incredibly excited by this, but the article mentions that another company, SynCardia already has a thousand of these devices deployed into Production.
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 angry when my cell phone dies after 12 hours.
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?
Wikipedia says 1982 was the first. From this article:
"""Heart-assistance devices have been used for decades as a temporary solution for patients awaiting transplants, but Carmat's bioprosthetic product is designed to replace the real heart over the long run, mimicking nature's work using biological materials and sensors."""
edit: the headline is a little confusing, but it's currently phrased "Carmat's first," a company formed specifically to advance the state of the art in synthetic organs.
Wikipedia cites this[0] account of the first transplant:
"""During the 112 days that he survived, he underwent four additional operations, had several episodes of bleeding, and experienced prolonged periods of confusion. He even asked to die on several occasions."""
The Jarvic 7/SynCardia temporary CardioWest Total Artificial Hear and Abiocor both seem to simulate a heart beat.
My brief research also suggests they are the most widely used devices (the support support system for the Jarvic 7 is down to 13 pounds!). I'm not familiar with the stuff, I just thought it was an interesting question.
This one actually regulates itself based on your physical activity. They also think it should beat faster if you're in a stressful or emotional situation (such as meeting with your crush). This is based on the fact that your blood vessels will dilate themselves and the artificial heart will compensate.
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.
On that note, it's important to set your expectations correctly on new medical technology. Early heart transplants were considered a success if the patient survived surgery long enough to wake up; it took a lot of work to go from that to many-year survivals.
I'm rooting for whoever got the first one of these off the line, but if he throws a clot and dies next week, keep in mind this shit is hard. Hopefully they'll work out any problems that develop, iterate on the product, and by the time most of us need one of these, they'll have 20-, 30-, 40-year survivals under their belts.
