Artificial Intelligence Diagnoses Heart Murmurs Better Than Expert Cardiologists
At the just concluded American Heart Association’s Scientific Sessions 2018 in Chicago, Eko, the makers of popular digital stethoscopes, showed off a neural network AI algorithm that is able to detect murmurs better than a group of cardiologists. The study, titled “Artificial Intelligence Detects Pediatric Heart Murmurs With Cardio (Read more...)
FDA Clears Canon’s Vantage Orian 1.5 Tesla MRI
Canon Medical won FDA clearance to bring to the U.S. market its brand new Vantage Orian 1.5 Tesla MRI scanner. It features a wide 71 centimeter bore and quiet operation thanks to its Pianissimo and Pianissimo Zen technologies. Pianissimo makes all scanning sequences quieter, while Pianissimo Zen allows certain scans to be performed at near [&hellip (Read more...)
Mental Illness Body Tracker Accurately Diagnoses PTSD
Mental illness can be notoriously difficult to diagnose in many cases, since symptoms may be invisible to physicians and those that are can be misleading. Objective methods that don’t rely on a direct observation would help to improve diagnosis. Researchers at Draper, the famous engineering firm in Cambridge, Massachusetts, have developed a s (Read more...)
Reminder: Medgadget 2018 Sci-Fi Writing Contest: Win The Eko Digital Stethoscope
It’s that time of the year when we call on technological visionaries, medical futurists, and creative people of all kinds to submit medical science fiction stories to our annual Medgadget Sci-Fi Writing Contest. At Medgadget, we keep a record of the progress of medical technologies and hope to inspire you to imagine a futu (Read more...)
REVA’s Fantom Encore Thin Strut Bioresorbable Scaffold Unveiled
REVA Medical, out of San Diego, California, has released its Fantom Encore bioresorbable scaffold. The implant is made with the company’s own Tyrocore polymer that is absorbed by the body over a period of some months, eventually disappearing while native tissue takes over. The process helps to make sure that the lumen stays open whi (Read more...)
Cedars-Sinai’s New App Offers Walking Directions Around Hospital
Hospitals can be famously difficult to navigate, and conventional GPS mapping apps don’t really help get through an indoor maze. Cedars-Sinai medical center in Los Angeles is solving this problem with its own smartphone app. The new Cedars-Sinai app has a built-in interactive map that gives step-by-step walking directions between any two poin (Read more...)
Adaptive Vapor Ablation for Menstrual Bleeding: Interview Maria Sainz of AEGEA Medical
Heavy bleeding during menstruation, known as menorrhagia, is often treated by endometrial ablation. There’s a number of methods of doing so, including delivery of heat, cold, and microwaves, but each has a number of downsides and limitations. AEGEA Medical is a Silicon Valley company that has developed a unique technology, called adaptive vap (Read more...)
Medtronic’s Valiant Navion Thoracic Stent Graft Cleared in EU
Medtronic won European CE Mark approval to introduce its Valiant Navion thoracic stent graft for treating lesions within the descending thoracic aorta such as thoracic aortic aneurysms (TAA), blunt traumatic aortic injuries (BTAI), and penetrating atherosclerotic ulcers (PAU). The system received FDA approval in October of this year. The Valia (Read more...)
PerQseal Absorbable, Sutureless Large-Bore Closure Device Coming to Europe
Vivasure Medical, a Galway, Ireland company, is launching in Europe its PerQseal closure device for use in large vessel femoral arteriotomies following large-bore transcatheter procedures, such as aortic valve replacements. Though minimally invasive transcatheter procedures have revolutionized cardiovascular care, closing the access sites (Read more...)
Point-of-Care BRCA1 Mutation Testing in 20 Minutes
BReast CAncer gene one (BRCA1) is one of the best-known genes linked to breast cancer risk. Unfortunately, the technology to spot the gene requires a lab and expertise at interpretation. Researchers at Louisiana State University have now developed a smartphone-based system called FLuoroZen that can test for the cancer-related BRCA1 mutation at the (Read more...)
Nanoneedle Skin Patch to Inject Drugs Into Cells
Delivering drugs directly into skin cells using microscopic nanoneedles may allow for highly effective treatment of skin conditions without injuring the cells that are treated. Silicon nanoneedles have been developed in the past that can do such a trick, but they’re stiff and can be painful, in addition to quickly losing their effectiveness. (Read more...)
Tiny New Pacemaker Small Enough for Infants
Researchers at Children’s National Health System, working with engineers from Medtronic, have created a pacemaker appropriately tiny enough to implant into infants. Measuring only one cubic centimeter, about the size of a large pill, it allows the device to be implanted inside the child in a minimally invasive fashion. Currently, because (Read more...)
DNA Origami Nanoparticles to Treat Acute Kidney Injury
DNA origami is a technique for building different shaped molecules out of the four standard nucleotide bases. Various forms can be constructed, such as tubes, pyramids, and cubes, and the shapes of these molecules can significantly affect their functionality. Now they’ve been shown to be useful for treating acute kidney injury (AKI). The (Read more...)
University of Missouri Research Reactor Now Supplying Iodine-131 for Thyroid Treatment
Medical radioisotopes are widely used in cancer treatment, but their production has been hampered to the point that obtaining them has become a challenge. The lack of Technetium-99m is probably the most widely known, but there’s also a shortage of Iodine-131 (I-131), a radioisotope commonly used for diagnosing and treating thyroid condit (Read more...)
