In a world first, clinicians at Maastricht University have used a robot to perform "supermicrosurgeries", which involved operating on vessels as small as 0.3 mm in diameter. The procedures were conducted on women with lymphedema, a condition that arose as a result of breast cancer, whose lymphatic vessels were connected to veins to provide a drain for lymphatic fluids that built up. This is normally very difficult, as working on such tiny vessels requires extremely stable hands. To overcome this, the researchers used the MUSA robot from Microsure, a Dutch...Read More
Scientists at University of Bordeaux/French National Institute of Health and Medical Research (Inserm) have developed a completely new biological material, made using human fibroblast cells, that can be turned into sutures, vascular grafts, and many other medical devices and tissue replacements. They showed that their Cell-Assembled extracellular Matrix (CAM) can be turned into yarns of different strength, flexibility, and to have various other characteristics. These yarns can be used as sutures, but also to create artificial vessels and other devices for implantation. Because these yarns are similar to those used...Read More

3D printing of tissues and organs requires a bio-ink that can host the living cells that are required for every unique application. A viable construct requires an extracellular matrix that will have the right mechanical and biochemical properties for the intended cells. Researchers at Rutgers University believe they're on track to being able to print a wide variety of tissues and organs thanks to a bio-ink that can be fine tuned so that living cells placed within structures printed using it will find comfort and proliferate as desired. The team...Read More
The blood-brain barrier is one of the greatest challenges that modern medicine has to overcome if we want to be able to fight neurological diseases using drugs. Animal models serve a purpose, but they're not very good at replicating the human blood-brain barrier (BBB) as results often don't translate during clinical trials. A better way to study the BBB is needed and researchers at Georgia Tech have now developed a chip that accurately replicates its function using the human cells that form this important part of our anatomy. Astrocyte brain...Read More
Velóce Digital Health is working to make pills smarter. The Denver, Colorado company is developing the SmartTab, an ingestible capsule that can be wirelessly controlled via a smartphone to release its contents at precise locations within the gastrointestinal system. SmartTab CEO Robert Niichel “The idea is that [with] the smart capsule, you will have precision medicine and delivered to a very targeted area,” says Robert Niichel, Founder and CEO. This approach, he points out, could reduce drug dosages, adverse effects, and improve patient outcomes. SmartTab works using several key technological...Read More

Onera Health, a company headquartered in Silicon Valley but with R&D offices in the Netherlands, has developed a bioimpedance patch, to be worn on the chest, that can detect sleep apnea. It has just been successfully trialed in 25 patients and the results show that it is about as accurate as automatic scoring using a traditional polysomnography respiration channel (sensitivity of 58.4%, specificity of 76.2%, and an accuracy of 72.8%). Because the device is fairly unobtrusive, and is worn on the chest, it has the potential to allow for sleep...Read More
Engineers at Rutgers University have developed a robot that autonomously draws patient blood and immediately performs hematology analysis. Such technology may help to speed up patient care, free clinicians to do other tasks, and even reduce the number of failed IV starts. The device was recently tested in a clinical trial for the first time and the results, published in journal Technology, showed that the robot is as good or better than trained phlebotomists at obtaining venous access. Currently, clinicians can miss target veins in patients who lack visible veins...Read More

The European Union cleared Profusa's Wireless Lumee Oxygen Platform, a system designed to measure tissue oxygen levels in patients with diseases such as peripheral artery disease and critical limb ischemia. The wired version of the Lumee was cleared in Europe back in 2016 and the new device fundamentally works the same. It consists of a small hydrogel sensor, which comes with its own injector, that has fluorescent particles attached to its body. An electronic wireless patch is placed over the spot where the sensor is injected under the skin. When...Read More

BioIntelliSense, a Silicon Valley firm, won FDA clearance for its BioSticker wearable sensor and the company is also releasing its Data-as-a-Service platform. The BioSticker can track heart rate, respiratory rate, skin temperature, body position, sleep status, and activity levels, as well as provide a high-resolution gait analysis, fall detection, and can even spot certain symptomatic events that need to be reported. All this can be recorded for up to a continuous thirty days, providing physicians with an impressive set of data that can hold clues to patients' diseases and conditions....Read More

Researchers at the University of Cincinnati have developed a tiny portable diagnostic device that can detect the presence of specific pathogens in a saliva sample, and relay the results to a doctor when plugged into a smartphone. The device can potentially diagnose a wide array of diseases, including malaria, HIV and Lyme disease, and could be useful for point-of-care testing and even self-testing. A custom app can relay the results of tests to one's doctor for nearly instant diagnostic results. The technology includes single-use plastic chips that a user places...Read More
Fitbit, a well know maker of wearable devices, is rapidly expanding into data-oriented health solution services. That was an overarching theme in our conversation with Amy McDonough, General Manager and Senior Vice President for Fitbit Health Solutions. She sat down with us recently to tell us about the company's offerings and how its solutions improve outcomes and decrease healthcare costs for consumers, employers, and insurance companies. The following is a description of our conversation with Ms. McDonough, taken from notes of the meeting, supplemented by additional information from the company....Read More
