As technological advances in implant design get more and more impressive, one hurdle seems to persist. How can you efficiently deliver power within the body? Many contemporary implants rely on single-use batteries while others require regular recharging, a process that is generally a frustrating one. Using a bulky charging device, one must synchronize the external inductive coil with the one inside the implant, eventually taking a few hours to fully charge and usually leading to some tissue heating and discomfort around the implant. Thus, new solutions that optimize power delivery while...
At the University of Michigan, scientists have developed a non-invasive technology to treat tinnitus, in most sufferers, by training the brain to "desynchronize" and to begin responding properly to real sounds. Their approach involves stimulating touch sensitive nerves using electrodes attached to the skin, while producing sounds, heard through headphones, that coordinate with the electric skin stimulation. This produces so called long-term depression (LTD) in the cochlear nucleus, which led to a reduction in tinnitus symptoms in both guinea pigs and in humans. (Of note, those interested in learning more...
Ultrasonic therapy, sonogenetics, and ultrasounic modulation are techniques that rely on focused, high precision sound waves to do things like stimulating neural cells to fire, motivating other cells to repair themselves, and killing tumors by damaging their cellular membranes. So-called cavitation bubbles, in which air bubbles rapidly vibrate, are the mechanism through which ultrasound acts on targeted cells and tissues, but the location of where these bubbles form is hard to pre-set accurately. This leads to limitations of what is possible, but researchers at Duke University are now attaching special...
Scientists at Lawrence Livermore National Laboratory have developed a way to create "brain-on-a-chip" devices that can be used to study brain function, how various chemical compounds influence it, and what can be done to protect the brain from toxic chemicals, etc. The technology may help lessen the need for laboratory animals, speed up drug development, and help us understand how the brain works at the cellular level. The development is part of the iCHIP (in-vitro Chip-Based Human Investigational Platform) project that aims to create ex vivo platforms that mimic the...
Biotricity, a Silicon Valley firm, won FDA clearance for its Bioflux ECG monitoring system. The 3-channel device is used to help spot and identify cardiac arrhythmias. The mobile cardiac telemetry system transmits any likely cardiac events via its built-in 3G/4G cellular connectivity. The triggers can be set and changed remotely by the patient's cardiologist, allowing for notifications to be programmed for each patient's unique needs (bradycardia, tachycardia, atrial fibrillation) and diagnostic requirements of the cardiologist. This allows patients to go just about anywhere while being monitored in real time. A remote...
Researchers at National Institutes of Health's National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed a special patch for Type 2 diabetics that helps to control glucose levels in a novel way. The technology, once fully proven out and optimized, may work for days or even weeks at a time. The patch is made of alginate, a material produced from algae, that is biocompatible and has the strength necessary to penetrate the skin when formed into needles. As such, the patch has alginate needles protruding from its bottom, but in...
Contact-free measurement of vital signs is already a reality, but with a few important limitations some of which researchers at Cornell University may be able to overcome. Currently used devices typically require the patient to be in close proximity to the sensor, and they're only able to measure the breathing and heart rates, along with body movement. Technology developed at Cornell involves tags worn on clothing, or just placed near the patient, that emit radio waves toward the lungs and heart to measure their activity accurately, while allowing the patient...
Almerina Mascarello is an Italian woman who is the first person in the world that is using a powered prosthetic hand with a sense of touch for every day tasks. Overall, the technology is a few years old, but many of the components, including power and processing, had to be miniaturized before it was practical enough to take home. The team of engineers that worked on the system, including from Italy, Switzerland, and Germany, have now done that and are trialing the technology with Almerina's enthusiastic help. Almerina has electrodes...
Continuous positive air pressure (CPAP) therapy is impressively effective for treating obstructive sleep apnea, a condition that can lead to high blood pressure, increased chances of stroke, diabetes, and other health issues. But, while CPAP therapy works really well, it also has an incredibly poor rate of patient compliance. Very few, if any, patients are excited for a chance to wear a breathing mask over their face as they sleep at night. CPAP masks wrap around the patient's head and are tightened in place with stretchy fabric to maintain a...
SANUWAVE, a company out of Suwanee, Georgia, won FDA clearance to introduce in the U.S. its dermaPACE system for treatment of diabetic foot ulcers. The system, cleared through the agency's de novo process intended for new types of medical technologies, delivers acoustic shock waves into wound tissue in order to stimulate healing. The company refers to this effect as Pulsed Acoustic Cellular Expression (PACE). An electrohydraulic technique is used to generate acoustic pressure waves at about 510 bar that have a fast rise time of less than 33 nanoseconds and a life...

A few months ago, Medgadget spoke with Jason Shelton, CEO of Telomere Diagnostics (TDx) about the new company’s TeloYears genetic test. Compared to other genetic tests, TeloYears assesses an individual’s telomeres, a biomarker that changes with age. TDx’s goal is to provide consumers a new way to quantify their aging progress through detailed insight about their telomere biomarker. By proactively identifying accelerated telomere shortening and more directly understanding the benefits of current lifestyle choices, individuals can make educated decisions related to factors like diet, activity, and exposure to environmental factors...
