Post myocardial infarction (heart attack), damaged heart tissue doesn't tend to heal very well. Not only is the pumping action weakened due to muscle cells dying, but the electrical signaling through the heart can also be impeded. Scientists at Trinity College Dublin have now developed remarkable new patches that mimic the electrical conductivity of heart tissue while being able to withstand the physical forces that a moving heart produces. Such patches may one day be used to help overcome some of the consequences of heart attacks and provide a matrix...Read More

Chronic wounds, such as those associated with diabetes, can be incredibly difficult to manage. Even the process of accessing and medicating the wound can be detrimental to healing. Researchers from University of Nebraska-Lincoln, Harvard Medical School, and University of Connecticut are now reporting on having developed an electronic bandage that can deliver multiple drugs deep into a wound and only when programmed to do so. Wounds require different drugs at different stages of progression, but simply placing topical medication on the wound is not optimal. The new bandage has tiny...Read More
The current coronavirus infecting thousands of people in China (COVID-19) is making public health authorities around the world responsible for screening millions of people going through airports, returning from cruises, and crossing borders by land. The number one tool is the thermometer and checking is usually done by placing it against the forehead of every individual undergoing screening. This is slow, tends to cause people to bunch together, and puts staff in close proximity to the people whose temperature they're measuring, all contributing to increased chances of transmission of the...Read More
Parkinson's disease doesn't have many treatment options, but early detection and monitoring of its progression can bring important benefits to patients. However, most Parkinson's patients are rarely assessed by movement disorder specialists and those only suspected of having the disease don't have any tools to help them detect changes in movement while outside a clinic. Now, the FDA has granted Breakthrough Device designation to nQ Medical, a firm based in Cambridge, MA, for its neuroQWERTY software that monitors psychomotor performance and fine motor function while a person uses their computer...Read More
Varian has won FDA clearance for its Ethos therapy technology, which the company describes as an Adaptive Intelligence solution for improved tumor targeting during radiotherapy. Adaptive therapy allows clinicians to target tumors based on imaging performed during treatment sessions. This is important, as the internal anatomy tends to shift and tumors can move away from where they were during prior CT, MR, or PET imaging. Better targeting should help with treatment outcomes while sparing healthy tissues from unnecessary radiation. The Ethos system provides planning and contouring tools that are powered...Read More

Caption Health, a company based outside of San Francisco, CA, won the first authorization from the FDA for an ultrasound software that guides clinicians at capturing images of the heart. The Caption Guidance software should work with any number of ultrasound system from different manufacturers, but currently it can only be used with a diagnostic ultrasound from Terason, of Burlington, MA, a part of Teratech Corporation. An apical two-chamber view of the heart captured by Caption AI. As part of the De Novo premarket review that the Caption Guidance software...Read More

A microCT image shows a 3D-printed scaffold with clear grooves meant for the deposition of live cells. The grooved lines hold ink deposited during the printing process. Scaffolds can be made in any shape, based on medical images, to fill the site of a wound. 3D printing replacement tissues and organs is still in the early stages of development, but it is clear that custom printed implants will have to integrate multiple types of cells in different locations in order to perform like native tissues. Researchers at Rice University have...Read More

BIOTRONIK won the European CE Mark for its Orsiro Mission drug-eluting stent. The device is intended for widening coronary arteries at sites of stenotic and in-stent restenotic lesions, and is designed to be delivered through some of the more tortuous vasculature. The device is the next generation of the Orsiro drug-eluting stent and the redesign comes with ten additional indications, such as acute coronary syndrome (ACS), ST Elevation Myocardial Infarction (STEMI), diabetes mellitus and complex (B2/C) lesions The "ultrathin" struts are only 60 μm (≤3.0 mm) in diameter, helping the...Read More

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
