Current imaging methods that are used to spot tumors don't provide much information about the rate of activity of the cells making up the diseased tissues. Breast cancer tumors, for example, are mostly classified into a few categories based on hormone receptor and HER2 expression. Researchers at Cancer Research UK Cambridge Institute and the Department of Radiology at the University of Cambridge are now reporting in Proceedings of the National Academy of Sciences that they've used magnetized particles to image the actual metabolic activity of breast cancer tumors. This may...

Abbott has announced that the FDA has given the company the first ever approval for a device to treat Parkinson's by delivering deep brain stimulation (DBS) to the internal globus pallidus (GPi), an area associated with motor function. The Infinity DBS system, originally developed by St. Jude Medical that became part of Abbott, already has approval to stimulate the subthalamic nucleus (STN) and ventral intermediate nucleus (VIM) for the treatment of Parkinson's, Essential Tremor, and some other movement disorders. "The internal segment of the global pallidus, or GPi, is a...Read More

Known in the racing community as “Monster” Mike Schultz, the 36-year-old from St. Cloud, MN has transformed the world of adaptive action sports in multiple ways. In 2008, Schultz suffered a knee injury during a snowmobile competition that resulted in amputation of his left leg above the knee. Limited by a prosthesis that didn’t perform as needed for competitive, rigorous sports, Schultz set out to create his own durable and versatile mechanical prosthesis, using his knowledge and experience of fabrication and tuning suspensions on racing equipment. Within seven months of...Read More

Bacteria can take a ride and proliferate on the plastic wrap that foods are commonly packaged in. Researchers at Penn State have developed a way to bond a non-toxic transparent antimicrobial material to the ubiquitous polyethylene wrap that meats, vegetables, and mushrooms are sold in. Raw beef inoculated with pathogens then vacuum packaged with the composite antimicrobial film, sealed and placed into refrigerated storage. The composite antimicrobial film significantly reduced foodborne pathogens on the experimentally inoculated surfaces of the raw and ready-to-eat muscle foods. The antimicrobial layer is made of...Read More

Argon Medical Devices, a company based out of Frisco, Texas, is launching two kits for retrieving inferior vena cava (IVC) filters. IVC filters are used to prevent pulmonary embolisms, but when a patient no longer needs one it has to be removed. The two Argon kits are designed to fish out any retrievable IVC filter on the market via the jugular vein. The devices feature an outer sheath integrated with a coil to accurately deliver appropriate strength at the distal end, helping to pop off the filter legs from the...Read More

Cook Medical is releasing in the United States its TriForce Peripheral Crossing Set, devices made to support percutaneous wire guides while performing interventions within the peripheral vasculature. In addition to helping to directly treat obstructions, the devices can also be used to inject radiopaque angiography contrast media to image the vasculature being worked on. The devices come in two lengths and four configurations, allowing doctors to select which are most appropriate for each case.

VivaLNK, a company out of Silicon Valley, has announced FDA clearance for its reusable multi-vital patch and a compatible software development kit. The device is stuck to the skin to record ECG waveforms, respiratory rate, heart rate, RR interval, and patient movement, and so has promise in helping to detect cardiac arrhythmias such as atrial fibrillation. Weighing in at only .26 ounces (7.5 grams), it has all the electronics of a single lead ECG, an accelerometer, a rechargeable battery, and wireless connectivity. It was cleared in the EU just last...Read More

The FDA has just approved the smallest pacemaker with atrioventricular (AV) synchrony, the Micra AV. The device, intended to treat AV block, a condition typically requiring a dual-chamber pacemaker, is small enough to remain completely inside the heart. It doesn't have any leads, nor any complications arising from them. It looks the same as Medtronic's Micra Transcatheter Pacing System, but features algorithms that can detect the movement of the heart and coordinate the pacing of the ventricle so it works efficiently in conjunction with the atrium. This is thanks to...Read More

Scientists at Tohoku University in Japan have reported in journal Advanced Materials Technologies on the development of a contact lens that moisturizes the eye using tears in a reservoir behind the lower eyelid. The eye can dry up when covered with a contact lens, often leading to serious cases of dry eye syndrome that can result in corneal wounds and inflammation of the eye. To overcome this, these Japanese researchers have created a contact lens made from a hydrogel that can carry an electric charge across its surface. By relying...Read More

Potential exposure to dangerous chemicals is a reality for many people working in mining and manufacturing, as well as medicine. While spills of liquids are easily detected, many gases are not. Sensitive wearable gas sensors stuck to the skin would be useful for gas exposure detection, but these devices have to be flexible, need a heating mechanism, and require an integrated electric power source to function. A team of collaborators from Penn State and Northeastern University brought their expertise together to create an inexpensive way to produce flexible and self-heating...Read More

Controlling body heat is important in a variety of situations, particularly during heavy physical exertion and when patients have high fevers. Currently there are few methods of lowering one's temperature, and many of those can be impractical, especially if a power source is required. Now, a team of scientists at the University of Missouri has developed a material that can cool the skin by about 11°F (6°C) and also act as a substrate for flexible body monitoring electronics. The new material may perform a variety of healthcare related tasks while...Read More

URGO Group, a French firm, announced that it will soon be releasing its URGOnight sleep training system, a product we got a glimpse of at CES 2019. The product consists of an electroencephalography (EEG) headband and a smartphone app that people can use to train their brains to sleep better. Utilizing EEG neurofeedback, the technology underlying the URGOnight has been used in sleep clinics for many years. Sleep onset latency and wakening frequency can be reduced by nearly half, as shown in previous studies. The headband has four dry electrodes,...Read More
