All humans are unique individuals, some of it due to the differences between our brains. Being able to identify the differences in the structure and activity of our brains may have enormous consequences for neurology and neurosurgery. While CT and MRI scans can’t yet provide a level of detail to diagnose many neurological conditions, res (Read more...)

HydrUStent’s Biodegradable Stents Could Improve Patient Outcomes
Stents are widely used in patient care, but a major complication is infection and, for many types of stents, the need for eventual surgical removal. HydrUStent, a startup based at the University of Minho in Portugal, hopes to improve those limitations. HydrUStent’s product is a ureteral stent made from a patented material that is antibacteria (Read more...)
Smart Stent Monitors Blood Flow, Detects Restenosis
Vascular stents are some of the most commonly implanted medical devices, keeping millions of arteries open to uninterrupted blood flow. Though they tend to work well at first, too many end up being re-stenosed by new deposits of plaque and scar tissue often forms in the vicinity, blocking blood flow through the stent. Typically, renewed […]
New Siemens Acuson Sequoia Ultrasound Beams Through Obese Patients
Siemens Healthineers is releasing a fresh update to its popular ACUSON Sequoia ultrasound system. The device can image deeper than before while maintaining a high quality output, an important capability for those on the front lines of the obesity epidemic. As an example, using the Deep Abdominal Transducer (DAX) that comes with the Sequoia, cl (Read more...)
3D Joint Space Mapping Helps Assess Arthritis Patients
At the University of Cambridge, scientists have developed a method of monitoring small changes in joints of patients living with osteoarthritis. The capability should give clinical researchers and physicians treating patients a new tool to better understand and deal with the disease. The technique relies on CT scans of patient joints, and it measur (Read more...)
Photoacoustic Computed Tomography May Replace Mammographies for Breast Cancer Screening
Though mammography helps to provide early detection of breast cancer, it is a modality that suffers from limitations, particularly in dense breasts. A new technology, developed at Caltech, may have the potential to eclipse mammographies for spotting cancerous lesions. The photoacoustic system sends near-infrared laser light into breast tissue and d (Read more...)
Elekta Unity, a Revolutionary Combo of MRI and Linear Accelerator, Cleared in Europe
Elekta won European CE Mark approval for its Unity system that combines magnetic resonance imaging with a linear accelerator for highly targeted, real-time radiotherapy. The technology was originally the brainchild of physicists at UMC Utrecht in The Netherlands. Before their research found breakthroughs, it was believed that combining an MRI machi (Read more...)
Simulation Software Helps to Repair Diseased Heart Valves
At this week’s Computer Assisted Radiology and Surgery conference (CARS 2018) in Berlin, scientists from the Fraunhofer Institute for Medical Image Computing in Germany will be showing off their unique software that helps to fix cardiac valves. Designed for minimally invasive procedures, which involve placing special rings that correct n (Read more...)
First High Intensity Focused Ultrasound System for Prostate Ablation Cleared in U.S.
EDAP, based in Lyon, France, now has FDA clearance to bring to the U.S. its Focal One high intensity focused ultrasound system. It’s used to ablate prostate tissue in a non-invasive way, relying on sound waves to resonate tissue apart at the cellular level. A urologist, using the system, combines imagery from previously obtained MRI [… (Read more...)
Sonavex’s EchoMark Soft Tissue Markers Receive FDA 510(k) Clearance
One year ago, we spoke with Sonavex CEO David Narrow about the Baltimore medical startup’s recent round of investment and ongoing development of its EchoMark and EchoSure products. At the time, David mentioned that the company was, “…preparing to submit our regulatory clearance materials.” This week, the company announced t (Read more...)
Health Technology Briefs from the ITF Demo Floor
Medgadget was recently invited to attend the imec Technology Forum (ITF) conference in Antwerp, Belgium. One of the highlights of the conference was the demo floor where imec, which is a non-profit R&D innovation organization, had the opportunity to show off some cool technologies from their research teams, spinoff companies, and partner organi (Read more...)
Tiny Battery-Free Implantable Devices Powered Wirelessly Using Radio Frequency Waves
Scientists at MIT have developed a wireless system that can power tiny implantable devices in the body, without the need for batteries. The system relies on radiofrequency waves emitted by an antenna outside the body, which can then power the implants from as far away as one meter and as deep as 10 cm below […]
Researchers Ease Process of Converting Patient Imaging Data Into 3D Printed Objects
Harvard’s Wyss Institute and MIT Media Lab have partnered together to create a way of crunching imaging data from different sources and modalities into a uniform computer file type called “dithered bitmaps”. After conversion, the images can be easily used to 3D print models of organs and other body parts, for example. This is (Read more...)
Now Available: Neural Analytics’ Lucid Robotic Ultrasound System for Brain Blood Flow Assessment
Neural Analytics, the Los Angeles based company that won FDA clearance a couple of years ago for its Lucid M1 Transcranial Doppler Ultrasound System, now won another clearance, this time for its NeuralBot robotic ultrasound positioner. The two devices work together and when united will be called the Lucid Robotic System. The NeuralBot automatically (Read more...)
New Transcatheter Aortic Heart Valve to Treat Regurgitation and Stenosis
JC Medical, based in Burlingame, California, has announced that its J-Valve transfemoral transcatheter aortic valve system has been implanted in the first patient to treat aortic regurgitation. Other transcatheter aortic valves available in the U.S. are indicated for aortic stenosis only, but the new device hopes to also treat pure aortic regurgita (Read more...)
Software Reads CT and MRI Scans, Guides Surgeons in Liver Resections
Liver resection surgeries are common procedures performed to remove a variety of cysts and cancers, intrinsic as well as metastatic. Liver resections are also done for transplantation purposes. Dangers lurk when removing parts of the liver because the dense and tortuous vasculature within can be hard to comprehend by the surgeon. Poorly placed inci (Read more...)
