Researchers at the University of Toronto have developed a new device to cultivate and test both atrial and ventricular cardiac tissue in the lab. The device, called Biowire II, consists of two elastic polymer wires which are positioned three millimeters apart, with a small band of cardiac tissue grown between them. A “training” regimen using […]

HemaShock Auto-Transfusion Tourniquet to Save Lives from Heart Attacks and Severe Bleeding
Patients undergoing a hemorrhagic shock or a cardiac arrest can be aided in many cases by restricting blood flow to the extremities, particularly the legs. Current methods are paintful and can be difficult to administer, while trapping lots of blood within the legs, as with conventional tourniquets. A new device from OHK Medical Devices, an […]
Pacifier-Activated Lullaby Helps Preemies Learn to Suck for Milk
Babies born prematurely often have a poorly developed sucking reflex, leaving them struggling to eat. A device called a Pacifier-Activated Lullaby (PAL) is now being tested at the UCLA Mattel Children’s Hospital to see whether it can teach preemies to suck for milk through a bit of gentle behavioral modification. Babies love lullabies, and it is […]
QTrobot Enhances Learning Opportunities For Children With Autism
QTrobot, pronounced “cutie robot,” was developed by the Luxembourgian company LuxAI and introduced to early adopters back in 2018. It is a expressive and engaging humanoid robot designed to assist in teaching autistic children essential social skills. One may think: “How can a robot help in the management of a condition characterized by impaired social […]
Microrobots Take Minutes to Detect C. diff in Stool Samples
Detecting bacterial infestations within the GI system, particularly using low cost methods, takes so much time that treatment is often administered too late. Clostridium difficile (C. diff) is a particular nasty nuisance that kills many frail patients, and even with a hospital lab it can take up to two days to get the results. Researchers at Chinese […]
Graphene Biosensors to Detect Lung Cancer
Exhaled breath is rich in biomarkers that can point to the presence of disease. In particular, ethanol, acetone, and isopropanol can point to the presence of lung cancer, so having a way of measuring these chemicals in breath might provide a way to diagnose lung cancers or to screen for them. Current methods of measuring […]
Tandem’s t:slim X2 Insulin Pump Classified as First Alternate Controller Enabled Infusion Pump
Tandem Diabetes received a brand new classification from the FDA for its t:slim X2 insulin pump. The device is the first in a category known as Alternate Controller Enabled Infusion Pumps (ACE pumps). According to the company, the associated indication is that the pump is “able to reliably and securely communicate with compatible, digitally connected devices, […]
Custom Tuned Hearing Aids from Comfort of Home: Interview with Adam Karp and Dr. Harvey Abrams of Lively
Lively, a New York-based hearing aid provider, has recently announced their online platform for customers to take virtual hearing tests, purchase hearing aids, and receive videocall support from doctors to fine-tune their hearing aids. The platform represents a telemedicine solution for the hearing-impaired, and allows people to receive treatment for their hearing loss from the […]
Vapotherm Releases Latest Precision Flow Hi-VNI Mask-Free Ventilation System
Vapotherm, a company based in New Hampshire, has released the latest version of its Precision Flow Hi-VNI system. The system is used to deliver non-invasive ventilation to spontaneously breathing patients using the company’s Mask-Free NIV technology. The latest version of the system features updated hardware and software, which purportedly improves on reliability and “to comply with […]
Wearable Respiration Sensors Made from Shrinky Dinks
While there are wearable monitors that measure a person’s respiration rate, they can’t track the volume of air that a patient inspires. For people with asthma and other lung conditions, this is an important indicator that can be used to assess the patient’s status. Engineers at University of California, Irvine have now developed a cheap and […]
Innovative Skin to Electrically Power Prosthetic Devices
Powered prosthetic devices need a great deal of electricity to energize them throughout the day. Researchers at the University of Glasgow in Scotland have developed a combination electronic “skin” that can generate and store electricity for prosthetic devices. The technology consists of layers of a finely tuned graphite-polyurethane composite covered by graphene, a material only […]
Ascyrus Medical Dissection Stent for Repair of Torn Aortas Cleared in Europe
Operative repairs of emergency type A aortic dissections require serious surgical skills and a complicated decision making process. Ascyrus Medical, a company based out of Boca Raton, Florida, just won the European CE Mark to introduce its stenting system that works as an adjunct to the current surgical repair. According to the company, its Ascyrus […]
Electric Generator Powers Cardiac Implants from Beating Heart
Cardiac implants, such as pacemakers and cardioverter defibrillators, have limited lifetimes because they’re powered by batteries that cannot be recharged. Replacement surgeries are required roughly every ten years, creating difficulties for patients, many of whom are already fragile, and incurring a huge cost on the healthcare system. Engineers at Dartmouth, working with clinicians at University […]
Photoacoustic Imaging Measures Temperature Deep Within Body
When using heat and other forms of radiation to ablate tumors, it is usually difficult to know just how hot the tissues around your target are getting, particularly when working deep within the body. MRI and ultrasound can be useful in many cases, but they have limitations and can produce misleading readings. To have a better […]
Spryng Calf Compression Devices for Workout Recovery: A Medgadget Review
As a gym rat and recreational runner, I’m often annoyed by sore muscles holding me back from that early-morning workout. That’s why I was excited to try Spryng, a calf compression device that debuted in 2018 at the New York City Marathon. The concept behind Spryng is pneumatic compression. Pneumatic compression isn’t a new idea […]
Soft Robotic Micromachines Mechanically Stimulate Small Tissue Samples
Researchers at Ecole polytechnique fédérale de Lausanne in Switzerland have developed miniature soft robots that can mechanically stimulate tiny tissue samples when activated by near-infrared light. The tiny machines could act as medical implants with a role in on-demand drug delivery or to mechanically manipulate tissues. Other applications include medical research, as components of lab-on-a-chip […]

Highly Dexterous Prosthetic Arm Gives Users Sensations
A woman in Sweden became the first person in the world to receive an osseo-neuromuscular hand prosthesis that is impressively accurate and that can even transmit sensations back to its user. The device is integrated with the patient’s remaining natural arm unlike anything else out there. It is the culmination of the DeTOP (Dexterous Transradial […]
Tumor Monorail Lures Brain Tumor Cells Toward Death, Now FDA Breakthrough Device
Brain tumors are extremely difficult to treat due to their hard-to-access location and because the blood-brain barrier prevents most drugs from reaching their targets. A new device called “Tumor Monorail,” which cajoles tumors to crawl into a container, just received the FDA’s “breakthrough” designation. The new designation will speed the device through the rest of the […]
Ingestible Pill Stays Inside Stomach, Monitors Digestion
There are a variety of gastrointestinal conditions that may be better treated if clinicians had an idea of what’s going on inside the stomach. But, the stomach is full of acid and it eventually expels whatever drops into it, making it difficult to have sensors operate inside for long periods of time. Researchers at MIT […]
