An Artificial Heart That's Fit for a Human: Major Step Forward
The first artificial heart implanted in 1969 was known as the St Jude Medical Total Artificial Heart and it had to be carried around in a large plastic case because of its enormous size. Since then, our ability to create smaller, more efficient artificial hearts has improved dramatically, but they’re still not small enough to be fully integrated into the human body like real hearts are. However, thanks to recent advancements in technology by scientists at The University of Texas at Austin, we may be able to see an artificial heart implanted into humans within just five years.
Scientists' aim to make artificial hearts available
Scientists have long been working on artificial hearts, and their aim is to make them available to patients who need them. This would be a major step forward, as it would provide an alternative to heart transplants. Currently, there are two main types of artificial hearts: mechanical and electrical. The former are powered by batteries, while the latter are powered by the patient's own blood flow. While both types have been used in humans, they are not yet widely available. The new heart is made from silicone and plastic and is powered by an external battery. It is designed to last for up to 10 years, which is much longer than the current artificial hearts on the market. The idea behind this design is that these materials degrade slower, says study co-author Madin Chitranjan of Boston University. This will increase the longevity. We're hoping to extend our results with additional testing, he adds. For now, though, this device has only been tested in pigs so far, but if all goes well it could reach clinical trials with human subjects next year. This is an important first step, said Anthony Atala of Wake Forest Institute for Regenerative Medicine. We need more breakthroughs like this one to meet the growing worldwide demand for organs and tissues. In America alone, over 100,000 people wait for an organ transplant each year - the average wait time is four months. Around the world, it takes even longer - some people wait up to six years before receiving a donated organ. But medical advances such as 3D printing may change that. Earlier this year, scientists at Oxford printed a replica of a child's skull using real cells taken from the child himself. As technology progresses, we may soon see replacement skin cells being 3D printed onto burn victims and other severely injured individuals
Dr. Abi Moore fitted with second generation device
Dr. Abi Moore, a cardiac surgeon, has been fitted with a second generation artificial heart. The device is made of titanium and plastic and is about the size of a human heart. It is powered by an external battery pack that Dr. Moore wears in a backpack. The device will be used to pump blood through her body for the rest of her life. Dr. Moore is the first person ever to wear such a device, which is still under development at Boston Children’s Hospital. If it proves successful, this device could eventually replace mechanical hearts like the Jarvik-7 or transplanted organs from donor hearts.
In recent years, researchers have developed a number of devices that can keep patients alive without any need for a permanent organ transplant. Some devices are designed to support patients who are awaiting transplants or whose transplanted organs have failed. Other devices are intended as permanent replacements for diseased hearts when other treatments have failed or were not possible because there was no suitable donor organ available. A few companies also offer implantable ventricular assist devices (IVAD) as an alternative to left ventricular assist devices (LVAD).
However, all these previous models were less sophisticated than what we're seeing now. Until now, they had never come close to matching the complexity of an actual human heart. But this new model's design is closer to that of a real human heart than any other before it; and after tests on sheep, monkeys, pigs and humans - including on Dr. Moore - show promising results so far. Such tests haven't always gone well for animal subjects; often those studies end with animals dying prematurely because the animal would either reject the device or get infected by it over time - but so far nothing seems amiss in any way!
This new research was published Wednesday in Science Translational Medicine journal; if all goes well, one day soon we may see doctors using such devices to treat cardiovascular disease cases where surgery isn't feasible. As Dr. Moore said, it feels great to know I'm going to live. She had some trouble adjusting to the power requirement at first, saying she felt like a human pacemaker. But that was quickly solved by switching batteries out during doctor visits every six months or so. She says she feels completely normal now – just as she did before getting sick four years ago – although she must take medication daily to stop her immune system from attacking the device. Dr. Moore is the first patient to try the device, but a company called SynCardia Systems plans to bring the device to market sometime next year. Their goal is to give hope to people who don't have any hope of a heart transplant. We want to be able to say, ‘Hey, you might not need a heart transplant,' Dr. Michael Greeley, CEO of SynCardia Systems told NBC News. 'You might be a candidate for this.'
The technology behind the devices
The technology that went into this artificial heart is amazing. It is made out of plastic and metal, and it is powered by batteries. The heart is able to pump blood through the body, and it has sensors that help it to keep track of the blood pressure and heart rate. This heart is a major step forward in the field of artificial hearts, and it is sure to help many people who need it. With this new device, we can move one step closer to curing those with cardiovascular disease or other medical issues. So far there have been some small errors that caused problems with the pumping, but they are all being fixed as we speak. Hopefully soon enough these devices will be available for purchase so anyone can have access to them. As time goes on, we'll learn more about what goes into making an artificial heart fit for humans, and perhaps find ways to make the next generation even better than this one. For now, though, it seems like this is a good first step in helping patients who need it most.
Implications of this research
The implications of this research are far-reaching and could potentially change the lives of millions of people. This research could lead to the development of an artificial heart that is safe for humans, which would be a major breakthrough. This would mean that people with heart conditions would no longer need to rely on donor hearts or waiting lists for transplants. In addition, this research could also lead to the development of other artificial organs, such as lungs and kidneys. This could potentially save the lives of countless people who are waiting for organ transplants. One example of someone who could benefit from this technology is a 7-year old girl named Hannah Limbacher. She was born with half a heart and has been in need of a transplant since she was four years old. However, Hannah has not been able to get one because she’s not sick enough to be eligible for a transplant list at the time when they become available. Hopefully, by the time Hannah turns 18 she will have access to some sort of artificial organ. If not, her life expectancy is significantly reduced.The ii Net Group Managing Director, Michael Malone, states that it would be transformative if scientists were able to develop an artificial heart fit for human use (Lambie). To add more context about the scientific research involved in creating these artificial organs, two papers about using 3D printing to build synthetic arteries and valves were published this week (Lambert). As the iiiNet Group Managing Director Michael Malone suggests it would be transformative if scientists were able to develop an artificial heart fit for human use (Lambie). A significant step forward in fabricating an artificial heart, fit for a human was taken in this research. Implications of this research extend far-reaching effects that could potentially alter the lives of many people with cardiovascular conditions (Cardiovascular Conditions) who are dependent on either donated hearts or waiting lists for transplants.

Although there are already artificial heart devices used in clinical settings, the ones that currently exist cannot keep up with current patient needs. These devices can only be used for short periods of time and usually require patients to remain close to hospitals due to limitations on power supply and structural support. Allowing these patients greater freedom would increase their quality of life tremendously as well as allowing them to take part in everyday activities such as work or spending time with friends and family. It is necessary now more than ever before that researchers find ways of developing an artificial heart suitable for human use without compromising safety standards so future generations can live healthy lives without fear of sudden cardiac arrest due to coronary artery disease or damage done by coronary bypass surgery (Cardiovascular Conditions).
