    Although the mere mention of "retinal scanner" may get the blood boiling in privacy advocates, the latest such device out of MIT sports a much more innocent soul. Researchers at the school have reportedly developed a method to "scan the retina at record speeds of up to 236,000 lines per second, or ten-times faster than current technology." This process will allow doctors to snap "high detailed 3D images of the eye," which can be used to non-invasively spot ocular diseases such as diabetic retinopathy, glaucoma, and age-related macular degeneration much earlier and more accurately. The process itself is dubbed optical coherence tomography (OCT), and while things seem to moving along as scheduled, it will still be "five years or more" before we see this thing commercialized.[Via MedLaunches]

    Although we've seen gait monitors and even prosthetic feet that assist individuals in regaining a more natural stride, scientists at Technion Institute of Technology in Israel have resorted to a head-mounted display for its rendition. This virtual reality device combines "auditory and visual feedback to improve walking speed and stride length in patients suffering from Multiple Sclerosis and Parkinson's disease," and provides the wearer with a "tiled-floor image" that apparently assists them in navigating nearly any terrain. The device is meant to take the place of normal muscle feedback mechanisms, and to provide said feedback to these disabled individuals so they can make adjustments and improve the efficiency of their walk. The HMD has already made its way to several medical centers and has purportedly yielded positive results, but there was no word on when this device would be commercially available.[Via MedGadget]

    Make no mistake, there's a plethora of devices out there aimed squarely at rudely disrupting your nap, but a technique that utilizes a gaudy head wrap and magnetic pulses could make the process of conking out a whole lot easier. Apparently, scientists can use relatively standard medical equipment in order to "stimulate the brain with harmless magnetic pulses," which essentially penetrate the nerves that control a type of deep sleep called "slow-wave activity." By forcing the brain to conjure these waves, it helps trigger deep sleep in even the "most chronic insomniac," and researchers are hoping that these methods could be used to create a machine that lets weary individuals get one fabulous power nap. Until then, however, may we suggest wading through every last Intel roadmap presentation you can find without ever losing focus, as this little trick seems to work quite well in corporate settings.[Via Spluch]

    While Monica Healthcare's AN24 fetal / maternal electrophysiological monitor won't go down as the first device to take a pulse on one's heartbeat outside of the hospital, it is being dubbed the "world's first" device to allow "mother's-to-be to keep a regular check on their baby's heartbeat without having to go into the hospital and be attached to a machine." The pocket-sized device operates on battery power, weighs under 100-grams, and specializes in "non-intrusive passive monitoring." Moreover, it can detect and differentiate between the mother and the baby's signals, and can transmit real-time FHR / MHR analysis data to via Bluetooth or USB to any applicable handheld / PC. Notably, the AN24 has gone from "a research device into a medically approved product in only two years," and if the EU testing continues to go well, the company expects the device to hit the market in the October timeframe.[Via MedGadget]

    In an attempt to create a more fashionable alternative to the wheelchair devices that handicapped children currently rely on to get around, a group of engineers at the Bath Institute for Medical Engineering, in consultation with parents and occupational therapists, have concocted the car-like Whizzybug. The all-terrain vehicle can reportedly handle asphalt and green pastures without issue, and sports a blistering top speed of two miles-per-hour. Additionally, it can be controlled by the caregiver or the youngster, weighs in at just under 70-pounds, has a "fully adjustable seating system with memory foam cushions and a programmable joystick," and to top things off, this bad boy even touts a trailer hitch for towing those weak Power Wheels rigs out of the rough. The devices are slated to be sold by the developing charity, Whizz-Kidz, "at cost," which means that interested parents will be looking at anywhere between £1,700 ($3,406) and £2,000 ($4,007) depending on options.[Via MedLaunches]

    If you thought ASTRO and NextSat were the only two autonomous robots frolicking around in testing environments, Raven would certainly beg to differ, as NASA has recently announced that the University of Washington's mobile surgical robot will soon be off to tackle surgical tasks whilst underwater. The 12th NASA Extreme Environment Mission Operations test will see the mechanical MD pick up the tools in a simulated spacecraft submerged near Key Largo, Florida, where the "mission will test current technology for sending remote-controlled surgical robotic systems into space." Thanks to a combination of wired and wireless networks, a trio of seasoned veterans back in Seattle will be dictating the movements remotely, as the bot attempts to "suture a piece of rubber and move blocks from one spindle to another." Interestingly, there was no word on whether Raven was scheduled to pick up the night shift at Seattle Grace upon its return from the depths.[Via MedLaunches]

    We get a little more creeped out each week or so, as a new form of minimally overtly invasive robotic creature somehow comes to life and sets its sights on perusing our innards. The newest species hails from Carnegie Mellon University's Robotics Institute in Pittsburgh, Pennsylvania, and was designed to "crawl across the surface of the heart to deliver treatment." The eerily-dubbed "robotic caterpillar" measures just a few centimeters in length and can scoot about at a blistering 18-centimeters per minute via "push and pull" control wires that reside outside of the body. The lead doctor on the project suggests that the critter could "allow procedures to be carried out without having to stop the heart, reducing the risk of illness linked to heart bypass surgeries," and moreover, insinuated that patients would spend less time recovering in the hospital after he / she was all sewn up. Apparently, the HeartLander could be available for human practice "within three to four years," but according to a director at the British Heart Foundation, "a lot more research is needed to determine whether something delivered to the outside surface of the heart can modify activity on the inside."[Via BBC]

    Considering that a BSOD within the robotic surgeon that's halfway through a critical operation on your innards is far from ideal, we're certainly in agreement with companies looking to make actual human doctors even better at their work. A team of Canadian scientists and engineers have concocted the neuroArm robot to allow doctors to perform microscopic operations on the brain in a more precise manner. Essentially, the uber-steady bot "will let doctors use surgical techniques on afflictions such as brain tumors that human surgeons are simply not dexterous enough to do," and when combined with a touchscreen stereoscopic viewer, it enables MDs to better visualize the area they're working with through advanced depth perception and "3D-like" imagery. The neuroArm system should hit clinical testing sometime within the next month or so, and if all goes smoothly (ahem), the long-term goal involves "manufacturing different versions" and selling them to a variety of hospitals.

    As technology continues to make doctors' lives a bit easier (not to mention saving a few in the process), we've got yet another device that can detect a potentially fatal problem long before mere humans can figure it out. The Indian-based Infrascanner is a "handheld, non-invasive, near-infrared (NIR) based mobile imaging device used to detect brain hematoma at the site of injury" within the most important stage of pre-analysis. The device could also aid in the decision to proceed with "other tests such as head Computed Tomography (CT) scans" when not "facilitating surgical intervention decisions." While the methods behind the scanning are quite sophisticated, the unit uses diffused optical tomography to convert the light differential data seen in the local concentrations of hemoglobin into "interpretative scientific results." Potentially best of all, however, is just how close this thing is to actually hitting hospital wards, as it's simply missing the oh-so-coveted FDA stamp of approval before it can see commercial use.[Via MedGadget]

    While we've seen a number of individuals turning to Nintendo's Wii to shed a few pounds, the next wave of exercise equipment seems to be filtering in. Just weeks after seeing Motivatrix's MX9 Workout Master, five companies have come together in an effort to "develop a communications protocol to establish a connection between home healthcare devices from different manufacturers so that they can exchange information with one another." Mitsubishi, Citizen, Sharp, Tanita, and Hitachi have jointly designed the standard as part of a Japanese healthcare project, which will be "used when interconnecting healthcare equipment such as blood pressure meters, weight scales, and blood glucose meters with home gateway devices." Notably, the protocol can applied to both wired and wireless configurations, and if all goes as planned, it should be rolled out en masse to manufacturers in the Spring of 2008.[Via DigitalWorldTokyo]

    Despite appearances to the contrary, there are in fact technologies other than inkjet printers that are being put to use to create or repair various human body parts, as evidenced by this latest bit of kit developed by Finland's VTT Technical Research Centre. Apparently, the contraption you see above makes use of a visible light, ultra short pulse laser to get the job done, which has the benefit of being considerably cheaper than other similar systems that rely on pricey "femtosecond titanium-sapphire pulse lasers." Despite that relative cheapness, the setup can pump out biomaterial structures as small as 700 nanometers, which can then be applied to tissue engineering scaffolds. According to the team behind it, the technology's already in the process of being commercialized, although we're guessing that it's still a ways off from coming in a home version.[Via Gizmag]

    While the school of the Ramblin' Wreck may be best known for its barrage of engineering graduates, the university has been on quite the medical trip of late, as researchers have reportedly developed a nanometer-scale generator after already cranking out nanowires that monitor your blood pressure. The aptly-named nanogenerators can produce "continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow," which translates into easy energy for implanted and worn medical gadgetry of the future. Interestingly, the project was funded by the likes of the National Science Foundation and our pals at DARPA, and while this invention may not quite match up with wireless charging (hey, we're scared of hospitals), the concept is novel nonetheless. So if you were hoping that dreams of implanted analysis of your vitals would suddenly cease, things aren't looking up for you.[Via MedGadget]

    Spray-on gadgetry isn't exactly new, but the possibility of spritzing a computer on your epidermis most certainly piqued our interest. A team of Scottish scientists have reportedly "developed a computer the size of a matchstick head, thousands of which can be sprayed onto patients to give a comprehensive analysis of their condition." The device(s) joins the ever-growing array of communication-enabled health sensors aimed at helping the elderly stay in contact with their doctors even in remote locations, and can compute a variety of inputs such as blood pressure, muscle movement, and pulse rate. The technology, dubbed speckled computing, can even be rigged to transmit information via radio waves, meaning that a full-fledged diagnostic report could get a whole lot less invasive if this stuff pans out.[Via MedGadget, photo courtesy of EISF]

    C'mon, linking actual brain cells to a silicon chip might sound a bit sensational at first, but considering the work that's already been done on replacement retinas and human brains, Ted Berger's recently-hyped work is pretty much right on time. Essentially, the USC researcher has spent the past decade or so "engineering a brain implant that can re-create thoughts," and moreover, certain implementations could even "remedy everything from Alzheimer's to absent-mindedness." We know, thoughts of instantaneous brilliance are running wild through your mind, and considering that Ted (and his highly-regarded team) have figured out how to link a silicon chip to actual brain cells and elicit responses, the possibilities are indeed nearly endless. Put simply, Berger hopes that brain disorders that are currently battled with intensive drug regimens with less-than-exciting side effects can be solved "by simply implanting a few computerized brain cells." Of course, the team admits that it's "years, maybe decades" away from hospital-approved apparatuses, but if you're interested in reading (a lot) more about "the future of brain science," grab your specs, prepare your paltry short term memory, and hit the read link for all the insight.[Via MedGadget]

    The competition in the oh-so-lucrative medical field is most certainly heating up as a plethora of physicians are moving from paper charting to electronic documentation, but now we're seeing a battle brewing solely in the connectivity realm. Following Bluetooth SIG's Medical Device Profile, the USB-IF is concocting a working group to "improve healthcare technology" and make the adoption of USB more widespread in the wellness arena. Essentially, the team's initial goal "is to define a USB Personal Healthcare Device Class specification," after which it hopes to implement USB onto devices such as "blood pressure cuffs and exercise watches." Aside from allowing doctors to more easily track and archive changes in a patients history, the added USB connectivity in the hospital ward will purportedly "facilitate the communication between patient and doctor," as home-based clients could easily send their readings directly to a doctor's inbox thanks to the digital interface. Notably, the USB-IF is claiming that the new Personal Healthcare Device Class "should be available for use in devices near the end of 2007," so you better get to training granny on the ways USB -- STAT![Via EverythingUSB]

  • Intelligent micro-drill carefully delves through tissue

    While the idea of a robotic surgeon always makes us a bit weary, a new micro-drill crafted in the UK is earning its stripes (and the public's trust) the old fashioned way: by executing its duties without harming someone. The intelligent medical drill was developed by Peter Brett and colleagues at the University of Aston and David Proops, a surgeon at University Hospital Birmingham, and is "used to bore small holes in the side of a patient's head so that a surgeon can install an implant." Aside from being just slightly creeped out at that imagery, a surgical device that has worked perfectly in three actual operations demands respect, as the device has successfully allowed doctors to "give profoundly deaf patients cochlear implants." This device stands out due to its uncanny ability to sense pressure, torque, and force, and can automatically shut down if it feels it's going to pierce a membrane that shouldn't be punctured -- and for all you fellows who greatly prefer your hair over just about anything, we're sure the implant industry is already checking into it.[Via NewScientistTech]

    MIT's brainiacs aren't exactly new to the world of partying, and now scientists at the MIT Media Lab have invented a way to "reversibly silence brain cells using pulses of yellow light." The presumably rave-inspired pulsing design offers up the prospect of "controlling the haywire neuron activity that occurs in diseases such as epilepsy and Parkinson's disease," which could theoretically lead to the creation of "optical brain prosthetics to control neurons, eliminating the need for irreversible surgery." Aside from being thrilled that this stuff could help us avoid dodgy robot-led surgeries, it could also help gamers who tend to suffer from epileptic fits when dealing with those head-mounted displays. Additionally, the team is also looking at utilizing the new system to more effectively study neural circuits, but considering that this technology has the ability to "exert exquisite control" over individual neurons within you dome, we certainly hope Big Brother doesn't get ahold of this.[Via Slashdot]

  • Radiofrequency treatment curbs asthma attacks

    Sure, there's quite a few way to circumvent the effects of asthma, but a new development coming out of McMaster University in Canada suggests that radiofrequency treatment can actually curb the amount of asthma attacks suffered by asthmatics. The device, which "uses radio waves to heat the muscle lining of patients' airways," is used to administer a trio of sessions, and while the actual root cause is still unknown, it seems to cause a reduction in the smooth muscle lining the airways, subsequently making breathing less of a chore. The probe isn't the most comfortable, however, as it must first make its way through your nose or mouth in order to reach the lung airways, after which the tip is "heated using radio waves." The procedure is known as bronchial thermoplasty, and while the funding company (Asthmatx) has yet to elicit a thumbs-up from the FDA, it could certainly become a viable alternative for asthma sufferers. It's about time these free-flying transmissions made up for the harm they've caused, eh?

    If you always thought the inkjet approach to healing broken bones was too much of a stretch, you'll probably be interested in the plastic portable splint. Designed by Ching-Sui Kao, Geremi Durand, and Maxime Ducloux, the device is intended to be used by extreme sports participants (guess that includes Wii Sports?) that typically set records in either completion times or amount of damage done to their bodies, and can set your newly-broken limb into place right on the side of the mountain. By wrapping the limb with a set of flexible plastic strips, linking them up with Velcro, and finally applying a sodium citrate-based gel over top, a chemical reaction creates a rigid structure that forms a cast around the arm or leg. Of course, doctors can remove the material at the hospital and apply a more medically-approved rendition, but if you're looking for an easy way to excuse yourself from class or work without actually forging a doctor's note, here's your ticket.

    There's a growing number of devices that not only monitor one's health, but can also transmit pertinent information back to remote caregivers, but SHL Telemedicine's latest gizmo takes things a step further by beaming your ECG results directly to your physician's mobile phone. The oddly-named CardioSen'C is a portable heart-monitoring system that gathers information from twelve electrodes strapped to one's chest and upper body, and once activated, transmits the results of the electrocardiograph instantly to a user-selected handset. Unlike similar systems already available in the US, SHL's iteration will be aimed at the Israel / European markets initially, and while we aren't exactly sure how much coinage such an advanced machine will cost to wear, you should probably make sure your insurance covers spontaneous service calls before you start lighting your doc's handset up with ECG results.[Via Israel21c]
