Tendon-Inspired Sutures Protect Fragile Tissues
Researchers at McGill University in Canada have developed bioinspired sutures that mimic the structure of human tendons. The gel-covered sutures are slippery and tough, reducing the damage caused by conventional sutures when used on soft tissues. Interestingly, the gel surface of the sutures may allow for advanced applications such as drug delivery (Read more...)
Ultrasound Technology to Decode Brain Activity for Brain Machine Interfaces
Researchers at Caltech have developed a non-invasive functional ultrasound system that can detect brain activity by listening to tiny changes in blood flow within the brain. The system could provide a viable alternative to invasive electrodes that are implanted into the brain for brain machine interfaces, such as those used in prosthetics. So far, (Read more...)
Huge 12 Megapixel Display for Breast Imaging FDA Cleared
Double Black Imaging, a Plymouth, MN company that specializes in medical displays and monitors, is releasing an impressive 12 megapixel monitor intended for use in breast imaging. At 31 inches in size, the Gemini 12MP can be used instead of two separate 5 megapixel monitors that are now ubiquitous in radiologic imaging. Two different mammography [& (Read more...)
Canon’s Premium Large Bore CT Coming to U.S.
Canon Medical is releasing its Aquilion Exceed LB advanced CT scanner that features an impressively large 90 centimeter bore. The wide opening and edge-to-edge extended field-of-view (90 cm) reconstruction will certainly allow for large patients to be imaged, but also gives more flexibility in patient positioning, as well as easier access during pr (Read more...)
Siemens MULTIX Impact C DR System Cleared by FDA
Siemens Healthineers won FDA clearance for its recently introduced MULTIX Impact C ceiling-mounted digital radiography (DR) system. The FDA also cleared the MULTIX Impact VA20, a new version of the existing parent DR system. Both devices are targeted toward clinics on a budget, but offer advanced capabilities, including helping to optimize settings (Read more...)
Catheter Stimulates Lymphatic Drainage for Heart Failure Treatment: Interview with Eamon Brady, CEO of WhiteSwell
WhiteSwell, a medtech company based in Galway, Ireland, has developed a catheter system to treat acute decompensated heart failure (ADHF). ADHF is often treated using diuretics to remove excess fluid, but this doesn’t work for every patient and can have side-effects. This latest technology consists of a catheter with an impeller pump that is (Read more...)
Imagio Opto-Acoustic Imaging for Breast Lesions FDA Approved
Seno Medical, a San Antonio, Texas firm, has won FDA approval to introduce its Imagio device that utilizes opto-acoustic imaging to help physicians identify whether breast lesions are benign or malignant. It is hoped that this non-invasive and radiation-free technology will help to reduce the number of biopsies that have to be performed. Opto-acous (Read more...)
HARPOON System for Mitral Valve Repair: Interview with Daveen Chopra, Edwards Lifesciences
Degenerative mitral regurgitation occurs when the mitral valve prolapses, causing blood to leak back into the atrium every time the heart beats. The condition can be asymptomatic for many people, but for some it can cause a variety of issues, including fainting, pain, and shortness of breath. Currently, open-heart surgery is considered to be the [& (Read more...)
Cios Flow Mobile C-Arm from Siemens FDA Cleared
Siemens Healthineers just announced FDA clearance to introduce its Cios Flow mobile C-arm in the United States. Developed for use in orthopedics, vascular surgery, trauma, spinal surgery, and other fields, it’s intended to be a general purpose C-arm that can be easily used in a variety of cases. The Cios Flow is a relatively compact [… (Read more...)
3D Imaging Illuminates Internal Structure of Brain Spheroids
Researchers at the Wyss Center in Geneva and collaborators have developed novel imaging and labeling techniques to view the internal structure of brain spheroids, and observe the morphology of single neurons in 3D. Brain spheroids, which the researchers term “mini brains,” are a cluster of different types of brain cells, and are culture (Read more...)
Nanodroplets and Ultrasound to Drill Through Blood Clots
Penetrating compacted and extensive blood clots has been one of the main challenges of vascular surgery. Various catheter-based devices have been invented and are in use today, but many patients present with plaques that are just too difficult even for the finest existing devices. Now, researchers at North Carolina State University and University o (Read more...)
Radiotherapy to Prevent Recurrence Post Brain Tumor Excision: Interview with Matthew Likens, President and CEO of GT Medical
GT Medical Technologies, a company based in Arizona, has developed the FDA-approved GammaTile system, which can provide localized radiation therapy for brain tumor excision sites. Its goal is to reduce tumor recurrence and enhance patient survival. The treatment consists of radiation seeds encased in a collagen substrate. These are easy to place at (Read more...)
