Researchers based in China and Switzerland have jointly developed electrically conductive artificial blood vessels that may serve as implants to replace diseased native vessels. The flexible and biodegradable constructs consist of a metal-polymer conductive membrane, and an electric current can be passed through the vessel when it is implanted in the body. The electric stimulation appears to encourage the proliferation and migration of endothelial cells, and may improve the integration of the implanted vessel with the surrounding tissue. It can also be used to deliver gene therapy or drugs into...

Many fields of medicine are undergoing a transformation due to the COVID-19 pandemic, as patients are kept away from clinics as much as possible. Patients are now regularly visited by their doctors over video calls, are asked to perform certain procedures on their own, and are prescribed medical devices that would normally be used by clinical staff. Heart monitoring is the most important component of medical care for millions of people suffering from cardiovascular conditions, particularly those most at risk from COVID-19 complications. But receiving a clinical grade electrocardiogram (ECG)...Read More

Abbott has received CE Mark approval for the Freestyle Libre 3 continuous glucose monitor, meaning it can now be marketed in Europe. Abbott has substantially changed the design for the first time since the launch of the initial Freestyle Libre. The company claims that the Libre 3 is the thinnest and smallest continuous glucose monitor in the world, at the size of two stacked U.S. pennies. Being so small, it's a lot more discreet than its predecessors. However, the price of the sensor has not changed, and Abbott aims to...Read More

Medgadget would like to congratulate Harvey J. Alter, Michael Houghton, and Charles M. Rice on receiving the Nobel Prize in Physiology or Medicine for their work in discovering the hepatitis C virus. Hepatitis C, a virus that infects liver cells and causes inflammation, certain cancers, and lymphomas, is fairly widespread among certain groups of people, and until its discovery it was impossible to screen donated blood for its presence. People were getting infected with something that resembled hepatitis B, but screening for hepatitis B would not detect this still unknown...Read More

Researchers at Caltech have developed a low-cost multiplex test that can rapidly provide three different types of data on COVID-19. The test can detect the presence of SARS-CoV-2, antibodies against the virus (potentially indicating a level of immunity), and inflammatory markers that could indicate the severity of COVID-19. Using blood or saliva, the test can provide a result in as little as 10 minutes. The researchers hope that it could soon be used by people at home to assess their COVID-19 status. Testing is a cornerstone in the fight against...Read More

The Aesculap Aeos Robotic Digital Microscope from True Digital Surgery and Aesculap is now available in the United States. The system consists of a robotic arm and digital displays, and the company claims that it allows surgeons to achieve superior visualization compared with standard optical microscopes during a variety of complex surgical procedures. The Aesculap Aeos includes software to help with visualization, including 3D digital visualization and a customizable Image Modes feature that allows the surgeon to augment what's seen to better discern the tissue or structure of interest. A...Read More

Masimo won FDA clearance for its Rad-G pulse oximeter, a rugged device developed with the help of The Bill & Melinda Gates Foundation. Originally created to spot-check patients for SpO2 (oxygen saturation), respiration rate from the plethysmograph (RRp), pulse rate (PR), perfusion index (Pi), and pleth variability index (PVi®), this latest generation of the Rad-G allows for continuous monitoring as well. Thanks to the new Rad-G sensor, the oximeter can be used on both adults and children, allowing the same device to be used on all patients without having to...Read More

Arriving as quickly as possible to the site of a medical emergency is a critical goal for any paramedic. It may be easy enough in urban and even rural areas, but when someone is stuck high up a mountain there are often no expedient options. Drones may offer help in certain cases, such as delivering external defibrillators for bystanders to use, but nothing can replace having a professional medic onsite. England's Great North Air Ambulance Service (GNAAS), which operates in areas where people go hiking through remote terrains, is now...Read More

Researchers at Georgia Tech have developed an ultra low-cost hearing aid, for which all the components cost in total less than $1. Designed to be worn by people with age-related hearing loss, the technology provides much of the functionality of conventional hearing aids, but at a tiny fraction of the price. The device may represent a lifeline for hundreds of millions of people worldwide who need a hearing aid but can’t afford one. Age-related hearing loss is very common, and it can be isolating for older people. “The ability to...Read More

Scientists in Australia are gearing up for clinical trials of a brain implant that may restore limited sight in blind people. Developed at Monash University in Melbourne, the Gennaris system involves bypassing the eye completely and targeting the vision center of the brain. A person would wear a pair of glasses outfitted with a camera that, via a computer, feeds what it is seeing to the brain implant. The wireless implant is positioned on the surface of the brain and it can generate 172 different bright spots that the person...Read More

Researchers at the National Institute of Standards and Technology (NIST), which is part of the U.S. Department of Commerce, have developed a new technique to 3D print soft objects, such as hydrogels, at a higher resolution than previously possible. The technique uses X-rays or electron beams to crosslink the gels, helping to create complex structures at a nanometer scale. The technique could have potential in creating engineered tissue constructs for regenerative medicine applications. Soft materials, such as hydrogels, have significant potential in tissue engineering, given their mechanical properties and biocompatible...Read More

Gyroscope Therapeutics, a retinal gene therapy company, has developed the Orbit subretinal delivery system (SDS). The technology is designed to deliver therapies to the retina without the need for invasive procedures, such as vitrectomies, which involve removing the gel-like substance within the eye, or retinotomies, which involve making a hole in the retina. The company hopes that by combining medical devices that allow minimally invasive delivery with innovative gene therapies they can develop transformative therapeutic strategies. Gyroscope Therapeutics recently announced that the FDA has granted 510(k) clearance for the Orbit...Read More
