The Future of Medicine: The Era of Artificial Hearts

05Between artificial knees, total hip replacements, cataract surgery, hearing aids, dentures, and cochlear implants, we are a society that is fast becoming transhuman. Basically, this means we are dedicated to improving human health through substitution and augmentation of our body parts. Lately, bioprinting has begun offering solutions for replacement organs; but so far, a perfectly healthy heart, has remained elusive.

Heart disease is the number one killer in North America, comparable only to strokes, and claiming nearly 600,000 lives every year in the US and 70,000 in Canada. But radical new medical technology may soon change that. There have been over 1,000 artificial heart transplant surgeries carried out in humans over the last 35 years, and over 11,000 more heart surgeries where valve pumps were installed have also been performed.

artificial-heart-abiocor-implantingAnd earlier this month, a major step was taken when the French company Carmat implanted a permanent artificial heart in a patient. This was the second time in history that this company performed a total artificial heart implant, the first time being back in December when they performed the implant surgery on a 76-year-old man in which no additional donor heart was sought. This was a major development for two reasons.

For one, robotic organs are still limited to acting as a temporary bridge to buy patients precious time until a suitable biological heart becomes available. Second, transplanted biological hearts, while often successful, are very difficult to come by due to a shortage of suitable organs. Over 100,000 people around the world at any given time are waiting for a heart and there simply are not enough healthy hearts available for the thousands who need them.

carmat_heartThis shortage has prompted numerous medical companies to begin looking into the development of artificial hearts, where the creation of a successful and permanent robotic heart could generate billions of dollars and help revolutionize medicine and health care. Far from being a stopgap or temporary measure, these new hearts would be designed to last many years, maybe someday extending patients lives indefinitely.

Carmat – led by co-founder and heart transplant specialist Dr. Alain Carpentier – spent 25 years developing the heart. The device weighs three times that of an average human heart, is made of soft “biomaterials,” and operates off a five-year lithium battery. The key difference between Carmat’s heart and past efforts is that Carmat’s is self-regulating, and actively seeks to mimic the real human heart, via an array of sophisticated sensors.

carmat-artificial-heartUnfortunately, the patient who received the first Carmat heart died prematurely only a few months after its installation. Early indications showed that there was a short circuit in the device, but Carmat is still investigating the details of the death. On September 5th, however, another patient in France received the Carmat heart, and according to French Minister Marisol Touraine the “intervention confirms that heart transplant procedures are entering a new era.”

More than just pumping blood, future artificial hearts are expected to bring numerous other advantages with them. Futurists and developers predict they will have computer chips and wi-fi capacity built into them, and people could be able to control their hearts with smart phones, tuning down its pumping capacity when they want to sleep, or tuning it up when they want to run marathons.

carmat_heart1The benefits are certainly apparent in this. With people able to tailor their own heart rates, they could control their stress reaction (thus eliminating the need for Xanax and beta blockers) and increase the rate of blood flow to ensure maximum physical performance. Future artificial hearts may also replace the need for some doctor visits and physicals, since it will be able to monitor health and vitals and relay that information to a database or device.

In fact, much of the wearable medical tech that is in vogue right now will likely become obsolete once the artificial heart arrives in its perfected form. Naturally, health experts would find this problematic, since our hearts respond to our surroundings for a reason, and such stimuli could very well have  unintended consequences. People tampering with their own heart rate could certainly do so irresponsibly, and end up causing damage other parts of their body.

carmat_heart2One major downside of artificial hearts is their exposure to being hacked thanks to their Wi-Fi capability. If organized criminals, an authoritarian government, or malignant hackers were dedicated enough, they could cause targeted heart failure. Viruses could also be sent into the heart’s software, or the password to the app controlling your heart could be stolen and misused.

Naturally, there are also some critics who worry that, beyond the efficacy of the device itself, an artificial heart is too large a step towards becoming a cyborg. This is certainly true when it comes to all artificial replacements, such as limbs and biomedical implants, technology which is already available. Whenever a new device or technique is revealed, the specter of “cyborgs” is raised with uncomfortable implications.

transhuman3However, the benefit of an artificial heart is that it will be hidden inside the body, and it will soon be better than the real thing. And given that it could mean the difference between life and death, there are likely to be millions of people who will want one and are even willing to electively line up for one once they become available. The biggest dilemma with the heart will probably be affordability.

Currently, the Carmat heart costs about $200,000. However, this is to be expected when a new technology is still in its early development phase. In a few years time, when the technology becomes more widely available, it will likely drop in price to the point that they become much more affordable. And in time, it will be joined by other biotechnological replacements that, while artificial, are an undeniably improvement on the real thing.

The era of the Transhumanism looms!

Judgement Day Update: Geminoid Robotic Clones

geminoidWe all know it’s coming: the day when machines would be indistinguishable from human beings. And with a robot that is capable of imitating human body language and facial expressions, it seems we are that much closer to realizing it. It’s known as the Geminoid HI-2, a robotic clone of its maker, famed Japanese roboticist Hiroshi Ishiguro.

Ishiguro unveiled his latest creation at this year’s Global Future 2045 conference, an annual get-together for all sorts of cybernetics enthusiasts, life extension researchers, and singularity proponents. As one of the world’s top experts on human-mimicking robots, Ishiguro wants his creations to be as close to human as possible.

avatar_imageAlas, this has been difficult, since human beings tend to fidget and experience involuntary tics and movements. But that’s precisely what his latest bot excels at. Though it still requires a remote controller, the Ishiguro clone has all his idiosyncrasies hard-wired into his frame, and can even give you dirty looks.

geminoidfThis is not the first robot Ishiguro has built, as his female androids Repliee Q1Expo and Geminoid F will attest. But above all, Ishiguro loves to make robotic versions of himself, since one of his chief aims with robotics is to make human proxies. As he said during his talk, “Thanks to my android, when I have two meetings I can be in two places simultaneously.” I honestly think he was only half-joking!

During the presentation, Ishiguro’s robotic clone was on stage with him, where it realistically fidgeted as he pontificated and joked with the audience. The Geminoid was controlled from off-stage, where an unseen technician guided it, and fidgeted, yawned, and made annoyed facial expressions. At the end of the talk, Ishiguro’s clone suddenly jumped to life and told a joke that startled the crowd.

geminoid_uncanny_valleyIn Ishiguro’s eyes, robotic clones can outperform humans at basic human behaviors thanks to modern engineering. And though they are not yet to the point where the term “android” can be applied, he believes it is only a matter of time before they can rival and surpass the real thing. Roboticists and futurists refer to this as the “uncanny valley” – that strange, off-putting feeling people get when robots begin to increasingly resemble humans. If said valley was a physical place, I think we can all agree that Ishiguro would be its damn mayor!

And judging by these latest creations, the time when robots are indistinguishable from humans may be coming sooner than we think. As you can see from the photos, there seems to be very little difference in appearance between his robots and their human counterparts. And those who viewed them live have attested to them being surprisingly life-like. And once they are able to control themselves and have an artificial neural net that can rival a human one in terms of complexity, we can expect them to mimic many of our other idiosyncrasies as well.

As usual, there are those who will respond to this news with anticipation and those who respond with trepidation. Where do you fall? Maybe these videos from the conference of Ishiguro’s inventions in action will help you make up your mind:

2013, As Imagined By 1988

bladerunnerTwenty-five years ago, Los Angeles magazine envisioned what the world would look like in the current decade. And unlike Blade Runner, they avoided the cool but standard science fiction allegories – like massive billboards, flying cars and sentient robots – and went straight for the things that seemed entirely possible by contemporary standards.

The cover story of the magazine’s April 3, 1988 edition showed a futuristic downtown L.A. crisscrossed with electrically charged, multi-tiered freeways permeated by self-driving cars. The article itself then imagined a day in the life of the fictional Morrow family of the L.A. suburb Granada Hills, as “profiled” by the magazine in 2013 by science fiction writer Nicole Yorkin.

LAtimes_2013aIronically, the magazine did not envision that it would one day go out of business, or that print media would one day be lurching towards extinction. Nevertheless, the fictional article and the world it detailed were interesting reading. Little wonder then why, earlier this month, the LA Times along with an engineering class at USC, revisited the archives to assess what it predicted correctly versus incorrectly.

Together, pro­fess­or Jerry Lock­en­our and his class made a list of the hits and misses, and what they found paints a very interesting picture of how we predict the future and how its realization so often differs from what we expect. Of the major predictions to be found in LA of the 2013, as well as in the lives of the Morrow family (get it?), here is what they got right:

Smart-Houses:
smart-house_vCe6I_25016In the article, the Morrows are said to begin every morning when their “Smart House” automatically turns on. This consists of all the appliances activating and preparing them breakfast, and no doubt turning on all the environmental controls and opening the shades to get the temperature and ambient lighting just right.

While this isn’t the norm for the American family yet, the past few years have proved a turning point for home devices hooking up with the Internet, to become more programmable and serve our daily needs. And plans are well under way to find a means of networking them all together so they function as one “smart” unit.

Self-Driving Cars:
chevy_env_croppedThe writers of the article predicted that by 2013, cars would come standard with computers that control most of the settings, along with GPS systems for navigation. They also predict self-driving cars, which Google and Chevy are busy working on. In addition to using clean, alternative energy sources, these cars are expected to be able t0 self-drive, much in the same way a pilot puts their plane on auto-pilot. Drivers will also be able to summon the cars to their location, connect wirelessly to the internet, and download apps and updates to keep their software current.

But of course, they got a few things wrong as well. Here they are, the blots on their predictive record:

Homeprinted newspapers:
news_appThe article also predicts that each morning the Morrows would begin their day with a freshly printed newspaper, as rendered by their laser-jet printer. These would be tailor-made, automatically selecting the latest news feeds that would be of most interest to them. What this failed to anticipate was the rise in e-media and the decline of printed media, though hardly anyone would fault them for this. While news has certainly gotten more personal, the use of tablets, ereaders and smartphones is the way the majority of people now read their selected news.

Robot servants and pets:
kenshiro_smallIn what must have seemed like a realistic prediction, but which now comes across as a sci-fi cliche, the Morrows’ home was also supposed to come equipped with a robotic servant that had a southern accent. The family’s son was also greeted every morning by a robot dog that would come to play with him. While we are certainly not there yet, the concept of anthropomorphic robot assistants is becoming more real every day. Consider, for example, the Kenshiro robot (pictured at right), the 3D printed android, or the proposed Roboy, the Swiss-made robotic child. With all of these in the works, a robotic servant or pet doesn’t seem so far-fetched does it?

Summary:
Between these four major predictions and which came to be true, we can see that the future is not such an easy thing to predict. In addition to always being in motion, and subject to acceleration, slowing and sudden changes, the size and shape of it can be very difficult to pin down. No one can say for sure what will be realized and when, or if any of the things we currently take for granted will even be here tomorrow.

For instance, during the 1960’s and 70’s, it was common practice for futurists and scientists to anticipate that the space race, which had culminated with humans setting foot on the moon in 1969, would continue into the future, and that humanity would be seeing manned outposts on the moon by and commercial space flight by 1999. No one at the time could foresee that a more restrictive budget environment, plus numerous disasters and a thawing of the Cold War, would slow things down in that respect.

In addition, most predictions that took place before the 1980’s completely failed to predict the massive revolution caused by miniaturization and the explosion in digital technology. Many futurist outlooks at the time predicted the rise in AI, but took it for granted that computers would still be the size of a desk and require entire rooms dedicated to their processors. The idea of a computer that could fit on top of a desk, let alone on your lap or in the palm of your hand, must have seemed farfetched.

CyberspaceWhat’s more, few could predict the rise of the internet before the late 1980’s, or what the realization of “cyberspace” would even look like. Whereas writer’s like William Gibson not only predicted but coined the term, he and others seemed to think that interfacing with it would be a matter of cool neon-graphics and avatars, not the clean, page and site sort of interface which it came to be.

And even he failed to predict the rise of such things as email, online shopping, social media and the million other ways the internet is tailored to suit the average person and their daily needs. When it comes right down to it, it is not a dangerous domain permeated by freelance hacker “jockeys” and mega-corporations with their hostile counter-intrusion viruses (aka. Black ICE). Nor is it the social utopia promoting open dialogue and learning that men like Bill Gates and Al Gore predicted it would be in the 1990’s. If anything, it is an libertarian economic and social forum that is more democratic and anarchistic than anyone could have ever predicted.

But of course, that’s just one of many predictions that came about that altered how we see things to come. As a whole, the entire thing has come to be known for being full of shocks and surprises, as well as some familiar faces. In short, the future is an open sea, and there’s no telling which way the winds will blow, or what ships will make it to port ahead of others. All we can do is wait and see, and hopefully trust in our abilities to make good decisions along the way. And of course, the occasional retrospective and issue congratulations for the things we managed to get right doesn’t hurt either!

The Autonomous Robotic 3D Printer!

Robo-printerTechnophiles and fans of post-apocalyptic robo-fiction, your attention please! As if the field of 3D printing was not already impressive and/or scary enough, it seems that patents have been filed for the creation of a machine that can perform the job autonomously. It’s called the Robotic Fabricator, a robot-assisted all-in-one design that can print, mill, drill, and finish a final product — and all without human intervention.

Typically, 3D printers require human handlers to oversee the production process, removing unwanted materials such as burrs on plastic and metal parts, repositioning and removing printed objects, getting rid of powdery residue from the interiors of intricate structures. But this machine, once complete, will take away the need for an operator entirely.

Roomba780_oben

The company responsible for this new concept is iRobot (no joke), the same people who brought us the Roomba vacuum robot. It features a flexible pair of robot arms and grippers that exhibit an impressive six degrees of freedom. And the platform is equipped with a series of sensors that tells the computer where it’s at in terms of the production, and when to employ the additive technique of 3D printing or the subtractive technique of milling and drilling.

3D_robotprinter

Naturally, iRobot plans to make the machine readily available to industries for the sake of producing and repairing a wide-range of consumer products. In terms of materials, the company claims it will be able to handle everything from ABS, polycarbonate, and silicone rubbers, to urethane rubbers, plastics, and low-melting-temperature metals, as well as combinations of these. What’s more, it will even be able to manufacture components for more autonomous 3D printers!

Picture it, if you dare. If this machine proves successful, it may very well become the precursor for a new breed of machinery that can assemble just about anything from scratch – including itself! As Futurists and Apocalyptics love to point out, machines that are capable of self-replicating and producing new and ever-increasing complex forms machinery is the key to the future, or to Armageddon.

Both fine choices, depends on what floats your boat!
