Moving Cells Using Ultrasound
Researchers at Caltech have developed a technique that lets them move groups of cells very precisely. It involves genetically modifying cells so that they express small protein air sacs in their interior. The sacs render the cells highly susceptible to manipulation using ultrasound waves, and the researchers can precisely move them into complicated (Read more...)

The technology is called the Paradise ultrasound denervation device and it has been developed by ReCor Medical, a medtech company with offices in California and t (Read more...)
Antibacterial Smart Sutures Visible in CT Scans
Researchers at RMIT University in Australia have developed ‘smart stitches’ that can fight bacteria and reveal the location of the sutured area in CT scans. The sutures have been developed to reduce the chances of surgical site infections and also make life a little easier for clinicians, as the material shows up in CT scans, […]
(Read more...)Terahertz Spectroscopy to Assess Severity of Skin Burns
Scientists at Stony Brook University in New York have developed a hand-held scanner that uses terahertz time-domain spectroscopy and neural network data analysis to non-invasively assess the severity of skin burns. At present, it is difficult to visually assess the depth of a burn injury, which could negatively influence treatment outcomes. The dev (Read more...)
Focused Ultrasound Releases Brain Biomarkers
Researchers at Washington University in St. Louis have developed a technique that can release difficult-to-access biomarker proteins from the brain. At present, the researchers are focused on releasing tau proteins that are implicated in Alzheimer’s disease and other neurodegenerative diseases. These proteins are typically locked behind speci (Read more...)
Tiny Patch for Cardiac Ultrasound Imaging
Engineers at the University of California San Diego have developed a wearable ultrasound system for cardiac imaging. The postage stamp-sized patch can be worn on the skin of the chest and uses AI and ultrasound waves to perform advanced imaging of the heart. The technology can even be worn to perform cardiac ultrasound imaging during […]
Ultrasound Tornado Rapidly Disrupts Blood Clots
A team of researchers at North Carolina State University have developed an ultrasound transducer that can disrupt blood clots in the brain quickly by creating an ultrasound vortex or ‘tornado’. The transducer is designed to be housed in a catheter that can be advanced through the vasculature until it reaches the site of a blood [&hellip (Read more...)
Exciting Medtech at the Healthcareᐩ Expo Taiwan
Medgadget was recently invited to Taiwan to cover the 2022 Healthcareᐩ Expo in Taipei. As is the case for most trade shows, the exhibit hall comprised a large portion of the expo. Consisting of over 2000 exhibitors in two massive halls, the main hall showcased the best of Taiwan’s healthcare industry. Here are some notable […]
Fluorescence Imaging System Illuminates Tumor Depth
Medical researchers at Washington University School of Medicine in St. Louis have developed a fluorescence imaging technique that allows them to illuminate a tumor in situ and calculate its depth below the surface of the body. The technique could assist surgeons in accurately removing a tumor and successfully excising an appropriate margin of healt (Read more...)
Soft Robot Grows Like a Plant to Travel Through Tight Spaces
At the University of Minnesota, researchers have developed a soft robotic system that can ‘grow’ like a plant. The mechanism allows it to travel through difficult-to-access areas, such as the tortuous gastrointestinal tract or vasculature. The system works by extruding a liquid through an opening in the device, and at the same time a ph (Read more...)
Mining Ultrasound Data to Improve Liver Diagnostics: Interview with Beth Rogozinski, CEO at Oncoustics
Oncoustics, a medtech company based in Ontario, Canada, developed the OnX Liver Assessment Solution, an AI-powered ultrasound-based diagnostic system for liver disease. At present, detecting liver disease is a challenge, potentially involving high-end imaging systems, specialists, and invasive biopsies. These challenges, and the related expense, ca (Read more...)
Ultrasound Sticker for 48 Hours of Imaging
Engineers at MIT have created an ultrasound patch that can provide long-term ultrasound imaging of internal organs and structures. The device contains a rigid piezoelectric probe array and uses an underlying layer of elastomer-covered hydrogel in lieu of the gel applied to the skin during conventional ultrasound procedures. At just the size of a po (Read more...)
Diamond Sensor for Smaller, Portable MEG Scanners
Researchers at RMIT University in Australia have developed a diamond sensor that can measure magnetic fields up to 10 times more sensitively than current sensors. The breakthrough could lead to a new generation of magnetoencephalography (MEG) scanners that are small and portable, and can function at room temperature. The researchers envisage that t (Read more...)
Magnetic Steering System for Guidewires
Percutaneous coronary intervention is an incredibly useful technique to minimally invasively investigate and treat cardiac issues, such as blockages in the coronary arteries, but it requires a significant amount of skill to perform safely and effectively. Manipulating a guidewire through the tortuous vasculature is not for the faint hearted, with t (Read more...)
