Most of the bionic eye systems we've seen involve clunky glasses-cam headgear, but the implantable camera now being developed at UCLA does it straight Terminator-style and keeps your face unencumbered. The camera, which researcher Michelle Hauer and her team recently filed a patent for, is small enough to be implanted directly on the eye's lens, and feeds image data to a chip at the back of the eye, where it can either be fed into the optic nerve to aid the blind, or just into a portable hard drive to aid the creepy. Hauer says power will come from on an onboard battery, but we're more interested in the mention of "optical control signals" in the patent application -- and by "interested" we mean "terrified of a zombie android army."

We've been hearing about cochlear implants of various sorts some time for some time now, but it looks things are about to get a whole lot more implantable, with a pair of fully implantable hearing aids now in clinical trials. One of those is developed by the folks at Envoy Medical, while the other comes from Otologics of Boulder, CO, which the MIT Technology Review got to check it out first hand, so to speak. Dubbed "Carina," the hearing aid consists of four separate pieces that are designed to be countersunk into the skull, including a microphone the size of a fingernail that sits behind the ear and a main processing unit that also houses the rechargeable lithium-ion battery that powers the device. That, as you're no doubt wondering, gets replenished by a charging unit that's held in place with a magnet and must be worn for an hour or two a day. As the Review heard straight from one of the device's early users, the entire setup appears to work remarkably well, delivering a "natural feeling of hearing." As it's quick to point out, however, the device still has a long ways to go, with the study currently only having twelve of the 70 to 80 users it needs to complete "phase II" of the trials. And, of course, there's that small matter of price, with the Carina currently ringing in at a cool $20,000 (for one ear), none of which is covered by insurance.

Truth be told, we've already seen instances where technology has enabled individuals to speak without speaking, but a brain implant placed into Eric Ramsey's head could certainly raise the bar in this field. The wireless electrode, which resides just six-millimeters below the surface of his brain, records pulses from 41 surrounding neurons involved in speech generation, and thanks to software developed by the associated team, those thoughts will hopefully be translated into words in the not-too-distant future. Currently, the group feels that they can accurately identify the word Ramsey is thinking up 80-percent of the time, and in the coming weeks, a computer will begin giving the patient real-time feedback so he can perfect the art of thinking out loud. 'Course, the team responsible isn't likely to be satisfied until an unadulterated conversation can take place, but it seems we're well on our way to seeing that come to fruition.

Man, that was quick. Just two days after reports hit the net about RFID implants being linked to cancer, VeriChip is lunging out to vehemently defend its own implantable microchip. Interestingly enough, the firm cites phrases from a number of studies to suggest that all is well and we've nothing to fear by getting one of these bad boys inserted into us, and it also makes darn sure we know the thing has been "cleared by the FDA as a Class II Medical Device." Lastly, the company has promised to continue looking at the "veracity and credibility of the studies," and noted that it would "take the necessary steps to ensure that our products remain safe to the end user." Phew, good thing, eh?

Although a number of unique diabetes treatments are already in the works, researchers at Johns Hopkins University are giving it a shot of their own with a newfangled intravascular implant. A team of undergrads have collaborated with doctors and biomedical engineers to develop a "specialized implant for a potential treatment of type I diabetes," which has been created for implantation inside the portal vein in order to dole out insulin when needed. The pouch would ideally be "impregnated with insulin-producing pancreatic beta cells," but researchers have insinuated that this same system could possibly be used to treat other ailments such as liver disease. Notably, users could actually have the pouch removed, refilled, and reinserted if additional treatment is needed, and while no firm timeframe has been settled on for release, a provisional patent has already been applied for and "animal testing" is set to start this summer.

Years back, scientists at the University of Bonn reckoned a visual implant would cure blindness, but unfortunately, the results were less than positive. While many alternatives have surfaced in the meantime, gurus at the institution are hitting back yet again with another option of their own, as the researchers introduced a software system that enables visual prosthesis to "learn" how to interpret sights in a way that the brain can understand -- something the original implementation had difficultly accomplishing. Essentially, an artificial retina "must learn to generate signals that are useful for the brain," and while the group's software should assist users with "flexible" central visual systems to garner new abilities in sight, they warn against "expecting miracles" too soon.

Researchers at the University of Southern California's Doheny Eye Institute have snagged the all-important FDA approval need to begin clinical trials of their bionic eye implant, joining a growing number of other groups following in Lee Majors footsteps. Once underway, between 50 and 75 patients suffering from retinitis pigmentosa and macular degeneration will be outfitted with the implant, which has already seen some degree of success in limited testing. As the image above shows, in its current form at least, the device isn't completely implantable, also consisting of a small camera mounted on a pair of glasses that's wired to a handheld device. It works by processing images from the camera and wirelessly transmitting them to a receiver implanted in the eye, which in turn sends signals to a series of electrodes that stimulate the retina, sending the information to the brain, all of which happens in real time. While it won't restore full sight, the researchers say patients should be able to detect light and distinguish objects from one another. If all goes as planned, they also foresee the device being commercially available shortly after the trials are complete, although it obviously won't come cheap, with an expected price tag of $30,000. Let's just hope a mirror shades version isn't too far behind.

We've certainly seen our fair share of tools for improving drug delivery 'round here, from the humble talking pill bottle to high-powered jet injectors to the ever-popular drug-toting, blood-swimming robots, but a group of European scientists seem to think there's still room for improvement, recently unveiling their Intellidrug tooth implant device. Technically a "dental prosthesis," the device is designed to find inside two artificial molars (which could cause a problem for those that still have their teeth) and deliver small doses of medication as needed, with the patient absorbing it in the mucous membranes of their cheeks. Of course, there's only so much medicine you can cram into a pair of teeth, with the scientists saying patient's should be able to store enough for a couple of weeks, after which they'll have to check in for a refill and a battery replacement. Most of us are likely still quite a ways off from running down to the neighborhood drug store to get our teeth topped off, however, with clinical testing of the Intellidrug only set to begin later this year.

Having one surgery is plenty, and having some foreign object implanted in your being is really pushing things, but knowing you're going to be under the knife every ten years or so to get a new battery is just absurd. Thankfully, a group of researchers in the UK feel the same way, and are well on their way to developing a battery-free pacemaker. Reportedly, the device would use a microgenerator producing electricity every time the patient moves, effectively eliminating the need for an internal battery. The cost of the £1 million ($1.96 million) project is being shared by the Department of Trade and Industry and private companies, one being Zarlink Semiconductor who has a large role in the device's development. Other teams around the globe are also seeking to create such a unit, with ideas spanning from tiny generators that receive power from heat right onto "biological pacemakers" that would correct heart problems without the need for a mechanical device. While there's no estimate as to when these gizmos will even hit the testing and approval phase, it seems that things are moving along quite well, but we have to stop and wonder how well a pacemaker powered by motion will function when you, well, cease moving.

Since the FDA gave the big thumbs up to a fully implantable artificial heart earlier this month, cardiac surgeon "Bud" Frazier and his team at the Texas Heart Institute aren't wasting any time in developing what they hope will be a fully-functioning, pulse-free artificial heart. The "continuous flow pump" channels deoxygenated blood through the entire body on a non-stop basis, and over two years of testing in cattle, has resulted in lengthening the lives of the previously terminal cud chewers. Replacement hearts that are currently available are too large to fit into folks without "large chest cavities" (including most women), and due to the vast quantity of moving parts, aren't guaranteed to function for an extended period of time. Frazier's alternative, however, is about the size of "an adult thumb," consists of a single moving part (the rotor), and has been designed to keep the blood moving for ten or more years. The HeartMate II can even respond dynamically to the needs of the body, so more blood is circulated when busting a move, and less is pumped when kicking back for a soothing game of competitive relaxation. While the long-term consequences of living a pulseless life are still under debate, Frazier's group is hoping to move forward with development -- and apparently challenge medical personnel everywhere to find a new way to monitor those vital signs.

In case anyone needed more proof that we're all living in a Philip K. Dick novel, a pair of hackers have recently demonstrated how human-implantable RFID chips from VeriChip can be easily cloned, effectively stealing the person's identity. Annalee Newitz and Jonathan Westhues showed off their handiwork at the HOPE Number Six conference in New York City this weekend, with Newitz herself playing the role of guinea pig, implanting a VeriChip RFID chip in her right arm. To clone the chip, Westhues first read Newitz's arm with a standard RFID reader, then scanned it again with a homebrew antenna connected to his laptop, which recorded the signal off the chip. He then used the same RFID reader to read the signal from his laptop, which promptly spit out Newtiz's supposedly unique ID. For its part, VeriChip has only said they haven't yet had a chance to review the evidence but still insist that "it's very difficult to steal a VeriChip."

We've run a few of these before, but if you think we're into otherwise unnecessary implantables, don't even get us started on implantables that enhance sensory perception, or restore senses where there were once none. The New Scientist has a writeup of a new kind of solar powered 1.5 millimeter x 15 micrometer retinal implant that could start restoring vision to the blind by using solar cells to trigger lead zirconate titanate piezoelectric actuators that stimulate optical neurotransmitters. Yeah, we slapped our foreheads too, it was so simple. You'll have Laxman Saggere of the University of Illinois at Chicago to thank when his invention is complete, though; we can't wait to give Stevie a peek -- the man wrote Songs in the Key of Life, can't he just get a peek?
