We're still a bit gun shy when it comes to surfing over to PEAK Surgical's website after watching that PlasmaBlade demonstration video, but a new release from the outfit affirms that said electrosurgery scalpel has just been approved for use by the US Food and Drug Administration. The "tissue dissection system," as it's so gruesomely called, has been given 501(k) clearance, meaning that PEAK can now market its tool for use in general surgery. So, anxious to camp out and be the first in the country to get sliced and diced by one of these? Bombard your local hospitals with phone calls starting next month.

Believe it or not, this actually isn't the first FDA approved personal hair remover we've come across, but for those looking for something capable of handling some seriously hairy ordeals, look no further than Silk'n. Created by Home Skinovations (har har), this unit relies on proprietary Home Pulsed Light technology to zap unwanted hair and bring back the smooth. Of course, this thing still has to be used "under the direction of a physician," but after waltzing into his / her office with three inches of sprawling chest hair blossoming from under that halfway buttoned shirt, we'd wager you'll have the requisite signature in no time.

It turns out that 17-year-olds probably aren't that good at studying electrical interference -- and its effect on pacemakers -- created by iPods. Unlike the data presented to the Heart Rhythm Society last year by a high-school student, which demonstrated the music player's ability to interfere with heart-regulating devices, the FDA now says that the gadgets are completely safe for use. Researchers measured magnetic fields produced by four different models of Apple's ubiquitous device, and found no reason why your grandmother can't keep jamming to her South of Heaven reissue. Said FDA researcher Howard Bassen, "Based on the observations of our in-vitro study we conclude that no interference effects can occur in pacemakers exposed to the iPods we tested." We hope the FDA will follow this up with a definitive study on the effects of boomboxes on hip implants.

Just in case our long-running series of posts regarding the danger / safety of cellphone and WiFi radiation didn't tip you off, an FDA-commissioned study was just published by the National Research Council of the National Academies of Science that basically says we've got a lot left to learn about the effects of all those radio waves. The FDA wanted to know where to concentrate research efforts in order to better understand wireless safety, and it looks like there are quite a few gaps in the research: the study says there needs to be further study on the effects of wireless radiation on children, pregnant women, and fetuses, both long- and short-term, and that frequency and power differences between different types of radiation need to be better understood in order to apply current knowledge to new products. All in all, it looks like there's a lot we don't know -- but that's not going to stop us from rocking this Bluetooth headset while browsing and taking a call.

Satiety, Inc. has finally found the funding it needs to push forward with a radical new approach to assisting the obese, as it has rounded up $30 million in financing from a number of venture capitalists who dug the idea. Essentially, the TOGa procedure is a "completely transoral process designed to achieve similar weight loss to restrictive surgeries," and it also claims to be less invasive, require less recovery time, and should create a "dramatically reduced amount of complications." In this system, the physician would "introduce a stapling device transorally and create a restrictive pouch at the entry of the stomach," and moreover, it's considered "non-surgical" in nature, endoscopic, and can be performed by properly trained bariatric surgeons, general endoscopic surgeons, and gastroenterologists. Currently, the firm is moving forward with plans to get the procedure approved by the FDA, and while there's no telling how long such a convoluted process will take, stomach stapling could see an entirely different approach in the years to come if this proves effective.

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.

Brace yourself Jack... remember the HairMax LaserComb? Yeah, well it's now FDA approved. Seriously, in the FDA trial some 93% of the participants saw an increase in hair density with an average increase of 19 hairs/cm. Of course, that stamp of approval doesn't necessarily mean those lasers will restore your hair, but at least it's not likely to singe the tuft you've got left. Just remember, the FDA also approved Olestra which can cause orificial leakage. Now go ahead, pony-up the $545 required to try 'er out. We sure as hell won't be going hands-on with this one.

Nice to see the future, as it looked in the 1970s, finally wrapping its hemp-crocheted arms around us. No, we're not talking jet packs and meals in a pill (though we'd like to be) we're throwin' more bionics at ya instead. The Harmony HiResolution Bionic Ear System from Boston Scientific just got the FDA's good house keeping seal of approval in addition to gaining a nod from Health Canada and the CE mark in Europe. The Harmony System, which combines a cochlear implant and behind-the-ear (BTE) device, delivers 120 spectral bands -- 5-10 times more than competing systems -- to the benefit of the severe-to-profoundly deaf with a love for music. That's right, when the implant is combined with the HiRes Fidelity 120 BTE external sound processor, users will gain access to CD-quality processing to help 'em better appreciate music while the automatic gain control adjusts amplification for soft whispers and loud sounds without adjusting clumsy controls. Approved for adults only in the US and available for that sweet, sweet implant by early 2007.

Despite having an air of pseudo-science about it, ultrasonic bone stimulation is actually a legitimate non-invasive therapy that's been clinically proven to heal certain types of fractures; and now, thanks to a recent FDA approval, this technology once reserved for fancy hospitals and doctors offices will soon be available for accident-prone individuals to treat themselves right at home. Specifically, the agency just gave the thumbs up to Smith & Nephew's Exogen 4000+ Bone Healing System, which is a portable device designed to stimulate growth in specific fresh fractures along with older ones that have not responded to traditional treatments. Twenty minutes a day is all it takes for a patient to speed up the healing of new fractures by up to 38% or give themselves an 83% chance of successful recovery from those hard-to-heal injuries. Before this new device convinces you to change careers and go all Evel Knievel, though, keep in mind that it's no miracle cure -- in order to completely toss aside concern for your personal safety, you'll have to wait around for those bone-repairing inkjet printers that we've been promised.
