Medtronic won the European Union CE Mark for its Micra AV pacemaker that's delivered into the heart, where it resides without requiring any leads, using a minimally invasive transcatheter procedure. The device is indicated for patients suffering from AV block, a condition that prevents proper electrical signal transfer between the atria and the ventricle. Micra AV addresses this condition by continuously monitoring the physical movement of the heart, using a built-in accelerometer, and adjusting how it paces the ventricle at every heartbeat. "This new device not only stimulates but is...Read More
After a long wait, the FDA has finally cleared Abbott's FreeStyle Libre 2 continuous glucose monitor in the U.S. for any patients with diabetes over four years of age. The system provides low and high glucose level alarms, which let patients know in real-time if they’re falling outside of their normal range and it doesn't require any fingersticks to calibrate it. Such technology can allow for significant improvements in patient comfort while offering exciting new capabilities for improved glucose management. The FreeStyle Libre 2 can take blood glucose readings as...Read More

Philips is releasing a fetal monitoring device in the United States designed to help pregnant women and their physicians keep a close eye on what's going on in the womb, while maintaining respect for ongoing social distancing recommendations. The Avalon CL Fetal and Maternal Pod and Patch are being made available thanks to the current emergency guidelines unveiled by the FDA in April in response to the COVID-19 pandemic. The system allows clinicians to keep a continuous eye on the mother's and child's heart rates, as well as uterine activity,...Read More
Samsung is releasing its top-of-the-line RS85 Prestige diagnostic ultrasound system. The device sports Samsung's latest hardware and software technologies, such as Crystal Architecture, to produce high quality ultrasound images. Moreover, the system can run a dozen or so intelligent software features that fine tune image quality in specific situations and provide measurements, assessments of blood flow, and other useful metrics. Some of the capabilities of the RS85 Prestige include LumiFlow, which makes color Doppler look like 3D, making it more intuitive to recognize where blood vessels are. ShadowHDR recognizes ultrasound...Read More
As of early May 2020, over 4.7 million people have been confirmed to be infected with the SARS-CoV-2 coronavirus[1], and governments are scrambling to contain its spread. The high R0 value (a measure of contagiousness- estimated to be between 2.0 and 3.02) of SARS-CoV-2 means that those infected copiously spread the virus and develop complications suddenly. As a result, health care systems are overwhelmed, and the effective delivery of medical care to all patients has become a challenge worldwide. Insufficient attention to early warning signs, inadequate stockpiling, lack of access...Read More
Microfluidic devices are analogous to circuit boards, and they can be programmed to perform all kinds of laboratory tasks on a small scale. They have the potential to perform all kinds of medical tests involving body fluids in a short time and using very small samples. While circuit boards pass electricity, which can be abstracted and quantified as bits, microfluidic devices tend to work with liquids that can mix with one another and contaminate each other. For microfluidic devices to approach the logic abilities of circuit boards, the fluids within...Read More
Researchers at Rice University have developed a method to 3D print soft structures that can reversibly change their shape in response to external stimuli, such as heat or an electric current. The researchers have dubbed their technique “reactive 4D printing” and it could have potential in creating adaptive biomedical implants that can respond to external stimuli for increased therapeutic functionality. Soft robotic implants have significant therapeutic potential, as they more naturally blend with the soft tissues of the body than rigid implants, and could interact with and manipulate tissues with...Read More
Researchers at the Terasaki Institute in Los Angeles have developed a microneedle patch to deliver mesenchymal stem cells (MSCs) into the skin. The biodegradable needles contain a gelatin matrix in which MSCs can survive. Once applied to the skin and removed, the needles detach from the patch and remain within the tissue. The hard outer shell of the needles breaks down over time and allows the cells within to provide therapeutic effects on the surrounding tissue. MSCs have significant therapeutic potential in a wide variety of disease states. They show...Read More

Being able to tell, in a matter of seconds, whether someone is infected with the virus that causes COVID-19 would certainly help put a halt to the ongoing pandemic. Existing tests typically involve a deep nasal swab to obtain enough fluid sample, which has to be transferred to a laboratory machine for processing, with the results usually available many hours or even days after. There are five minute tests on the market, but those still require an expensive machine at each testing site. Now, researchers at Ohio State University have...Read More
Researchers at the University of Colorado Denver have developed a method to 3D print liquid crystal elastomers so that they form complex structures with physical properties that match those of complex biological tissues, such as cartilage. The researchers hope that the technique will help with creating patient-specific implants to replace tissues that have been lost because of injury or disease. At present, generating replacements for diseased or injured tissue is challenging. Tissues have unique properties, such as flexibility and strength, that are difficult to emulate when using synthetic substances. Tissues...Read More

Ocutrx, an augmented reality (AR) start-up based in Irvine, California, is releasing an ophthalmology visualization system designed to make it easier for surgeons to perform procedures. Right now, ophthalmologists have to remain in constrained positions for long periods of time as they work with a microscope, but the OR-Bot from Ocutrx helps to alleviate some of the limitations of eye surgery by allowing the camera to be separate from the standard optical microscope, thereby giving a great deal of freedom in terms of how the surgical field can be visualized...Read More
