tDCS has come a long way from Giovanni Aldini's 1802 pioneering treatment of Luigi Lanzari...

Transcranial direct current stimulation (tDCS) has become a widely used technique for reaching into a person's brain and altering the way in which it functions. Vanderbilt psychology Professor Geoffrey Woodman and graduate student Robert Reinhart have just published the results of a new study in the Journal of Neuroscience in which they found that tDCS stimulation of the mediofrontal cortex for a period of minutes can change one's ability to recognize and learn from error for a period of several hours.  Read More

RevMedx's XStat syringe injects hemostatic sponges into deep wounds to control hemorrhage ...

Uncontrolled hemorrhage (bleeding out) is responsible for 80 percent of combat deaths. About the same proportion of those who die after being evacuated to a medical treatment facility also die of hemorrhage, usually associated with deep arterial wounds that cannot be treated using tourniquets – people die because we can't plug a simple hole. Now RevMedX, a small Oregon startup, has developed an alternative approach to treat such potentially survivable injuries.  Read More

Students of the Biodesign program design MetaboShield to fight obesity and reverse type 2 ...

MetaboShield, is an innovative intestinal sleeve that can be lodged permanently in the small intestine via the throat in an anesthesia-free procedure. Though it is still a prototype, when developed the sleeve could help people shed unwanted pounds and potentially help reverse type 2 diabetes.  Read More

While the word prosthesis usually evokes images of artificial legs, arms, and these days even sophisticated thought-controlled hands, an entirely new class of replacement body part has now become a reality – the bionic eye. One of the pioneers in this field is California-based Second Sight and the company has now announced that its Argus II System has received U.S. market approval from the Food and Drug Administration (FDA).  Read More

GE's new Silent Scan technology is designed to significantly decrease noise during MRI sca...

GE Healthcare has introduced a new data acquisition technology designed to improve patient comfort by largely eliminating the horrible noise generated during an MRI scan. Conventional MRI scanners can generate noise levels in excess of 110 dBA (creating a din that sounds like a cross between a vehicle's reverse warning horn and a Star Trek phaser) but GE says its new Silent Scan MRI technology can reduce this to just above background noise levels in the exam room.  Read More

The AliveCor Heart Monitor attaches to the back of an iPhone 4 or 4S

AliveCor’s smartphone Heart Monitor has received FDA approval and will go on sale to healthcare professionals in the United States in January 2013. The AliveCor Heart Monitor allows the recording, display, storing, transferring, and evaluation of single-channel electrocardiogram (ECG) rhythms using an iPhone 4 or 4S.  Read More

While there are many methods for preventing HIV transmission that work in principle (abstinence, safe sex, monogamy to some extent), in practice efforts to prevent new HIV infections have reached a plateau - about 50 thousand new cases are reported every year in the United States and no progress has been made on reducing this number for at least 15 years, with the overall rate of infection remaining stable since at least 2004. In response to the almost complete lack of effective prevention methods, the U.S. FDA (Food and Drug Administration) has now approved the prophylactic use of the anti-retroviral combination drug Truvada, to reduce the risk of people acquiring HIV.  Read More

The VeriChip is the
 size of a grain of rice

As reported way back in the first issue of Gizmo, US-based Digital Angel has produced the VeriChip, an implantable computer chip which monitors human biometric functions and transmits the data with GPS technology. The VeriChip has now been approved for human medical use by the Food and Drug Administration (FDA) of America, opening up the age of implantable technology. The VeriChip system is already being used in a variety of innovative solutions, including monitoring the vital stats of at-risk patients, farm animal management systems, locating stolen property, managing commodity supply chains, monitoring the location of parolees and providing a tamper-proof means of identification for enhanced e-commerce security. The FDA's green light of the VeriChip will help doctors access stored medical information about their patients and speed delivery during medical emergencies.  Read More
