While preeclampsia is a common and dangerous complication in pregnancy, characterized by high blood pressure, it is currently only diagnosed by doctors within a clinical setting. We at Medgadget recently reported on a preeclampsia test, developed at Purdue University, that can be used at home, and now researchers have actually had pregnant women try to do it themselves. The so-called supine pressor test was developed decades ago, but eventually it became uncommon because of variations in how different clinics and clinicians would perform it. Inconsistencies led to inaccurate results. By...

There has been a lot of progress over the past few years in the field of brain-computer interfaces, a technology that may give severely paralyzed people the ability to use robotic arms and legs. As anyone with two arms knows, one is not enough for many tasks. So researchers at Johns Hopkins University have successfully implanted two microelectrode arrays, one on each side of a disabled man's brain, that have been used to control two independent robotic arms and to also deliver tactile sensations. This is the first time that...Read More

OmniVision Technologies, a Santa Clara, California firm, just announced that it has won the Guinness World Record for "The Smallest Commercially Available Image Sensor". The OV6948 sensor was designed for use in catheters and endoscopes, allowing these devices to be as small as possible while also providing high quality imaging from within the body. Measuring only 0.575 mm x 0.575 mm x 0.232 mm, the sensor was identified by Transparency Market Research, an Indian firm, as the smallest commercially available imaging device. It provides 200 x 200 pixels of acquisition...Read More

For most people, the process of blood donation appears simple and straightforward: you lounge on a chair for 20-30 minutes as your blood collects into a bag, grab a cookie and some juice, then head back to the rest of your day. Behind the scenes, however, running a blood bank can be a complex operation. Donations must be correctly typed, labelled, catalogued, and stored. And in the case of plasma, donations must be carefully kept at a proper temperature, around -32ºC (-26ºF). In much of the world, plasma storage consists...Read More

Fidmi Medical, a company based in Israel, won FDA clearance for its new low-profile enteral feeding device. The product is designed to help overcome many of the challenges presented by percutaneous endoscopic gastrostomy (PEG) tubes, especially dislodgements and clogging of the inside. The Fidmi product can be delivered as the initial tube, as well as a replacement for previously implanted devices through procedures already established for PEG tubes. It has a flexible mechanism that prevents the device from moving out of its proper location. It also features a swappable internal...Read More

ResMed is releasing a new nasal cradle CPAP mask that features a front-facing tube that points downward. The AirFit N30 mask is the first of its kind, as similar masks typically have the air tube connect on top of the head, which makes them uncomfortable for many patients. The AirFit N30 is also ResMed's lightest CPAP mask, and the company has been trying to minimize weight across its product portfolio. The device is adjustable thanks to elastic headgear and a novel nasal cradle cushion, positioned below the nasal bridge, helps...Read More

A clinical trial, partly based at the University of Virginia Center for Diabetes Technology, has shown that an artificial pancreas, consisting of a continuous glucose monitor (such as the Dexcom G6) coupled with an insulin pump, can more effectively control blood glucose levels in patients with type 1 diabetes than conventional treatments. The system measures glucose levels continuously, and automatically administers insulin. The results suggest that such closed-loop systems could be a viable option in blood glucose management. The International Diabetes Closed-Loop Study included 168 patients with type 1 diabetes....Read More

We previously interviewed Humm, a San Francisco-based neuroscience company, when they had first released their Edge headset – an electrical stimulation device that helped users by boosting their working memory. Humm is focused on helping people continue to learn and grow throughout their lives. The idea behind their innovations is that through stimulation of the prefrontal cortex—a crucial area of the brain for decision making and learning—people’s ability to process and store information will be improved. Humm uses a safe and proven method of electrical stimulation called tACS (transcranial alternating...Read More

The thing that separates us apes from monkeys is the range of motion of our shoulders. Able to swoop from vine to vine, apes have a very complex joint whose motion hasn't been studied in full detail. That's because it is very difficult to position sensors on and around the shoulder that will conform to the shoulder and stay in place as it is exercised. When one's shoulders are injured, the typical way of measuring recovery is with a simple protractor that simply indicates how many degrees of movement the...Read More

Antibiotics are usually only needed at particular sites, where infection is likely to start. Yet, they're delivered throughout the entire body via pills and injections. This results in poor localized effectiveness, unnecessary effects on the rest of the body, and sometimes leads to the development of resistance. Researchers at Flinders University in Australia and National Institute for Materials Science in Japan have joined forces to develop a special nanomesh material that can release antibiotics in a programmed way precisely where they're needed. The nanomeshes were produced using electrospinning, a process...Read More

Founder of both InTouch Health and Computer Motion, Dr. Yulun Wang is considered one of the fathers of modern surgical robotics. Originally a graduate of University of California, Santa Barbara, Dr. Wang developed AESOP (Automated Endoscopic System for Optimal Positioning), the first FDA approved surgical robot, and the ZEUS Robotic Surgical System. ZEUS was used in the world’s first telesurgery procedure, known as the Lindbergh Operation, back in 2001. Both AESOP and ZEUS systems predate the well-known da Vinci surgical system developed by Intuitive Surgical following its merger with Computer...Read More

People who have hearing loss because of inner ear damage or from a poorly functioning auditory nerve are not helped by cochlear and middle ear implants. Auditory brainstem implants (ABI), which bypass most of the hearing system and send signals directly to the auditory brainstem, are the best option for such patients. But currently these devices rely on rigid components that do not fit perfectly with each patient's unique anatomy. This may be one of the reasons that ABIs end up being largely ineffective in many patients. Now, a team...Read More
