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 […]

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...)
Responsive DBS for Parkinson’s Disease Adapts to Patient’s Changing Needs
Deep brain stimulation (DBS) for Parkinson’s disease management has been shown to be quite effective in controlling the symptoms of the disease. Yet, the technology currently available to patients is rudimentary in that the neurostimulation delivered is constant and doesn’t take into account the changing needs of the patient. A sma (Read more...)
IQcool Warm System FDA Cleared to Cool and Rewarm Patients
BrainCool, a Swedish company, obtained FDA clearance for its IQool Warm System. The device, the name of which seems to be intended to be an oxymoron, can be used to both cool and reheat patients. The company’s first FDA cleared product, the IQool, which looks identical to the newly approved one, is indicated for rapidly […]
Soft and Highly Flexible Neural Interfaces Prevent Injury to Brain
While rigid neural interfaces can read brain activity and stimulate it quite well, these devices end up damaging the soft brain tissue they come in contact with. Moreover, the body ends up attacking these implants and forming protective layers around them that quickly degrade the electrodes. “Imagine you have a bowl of Jell-O, and you [&helli (Read more...)
EMBOTRAP II Pulls Clots from Brain With Minimal Compression: FDA Cleared
CERENOVUS, a Johnson & Johnson company that was built by combining Pulsar Vascular, Neuravi, and Codman Neuro’s neurological business, won FDA clearance for the EMBOTRAP II Revascularization Device. The stent retriever is used to pull blood clots from the brain, restoring blood flow and hopefully preventing the terrible consequences of a (Read more...)
AI Detects and Measures Small Vessel Disease in Brain CT Scans
Clinicial researchers at Imperial College London and the University of Edinburgh have developed an artificial intelligence software for identifying and quantifying small vessel disease, a frequent cause of dementia and stroke in older people, from CT scans. The investigators have already tested the software at Imperial’s Charing Cross Hospita (Read more...)
Brain-Computer Interfaces Work Best When Users and Computers Learn from Each Other
Brain-computer interfaces (BCI), which are able to read brain activity and turn the data into real actions such as moving a wheelchair, have the potential to liberate many severely disabled people. While a lot of progress has been achieved in this field, BCIs are still extremely limited in what they’re able to achieve and how […]
Patient with Difficult to Reach Tumor Saved Using Transoral Robotic Surgery
A man with a cancer called chordoma, which afflicted the bones in the skull base and spine, has had a novel transoral robotic surgery (TORS) performed on him to remove a difficult to access tumor. The clinical team at the Hospital of the University of Pennsylvania, which developed a set of TORS techniques, managed to […]
Brain Stimulator May Help Recover from Stroke
Ohio State University is reporting on a study its researchers are performing that’s evaluating a brain stimulator for treating the consequences of strokes. Specifically, a device made by MicroTransponder, an Austin, Texas firm, is used to stimulate the vagus nerve while a patient performs traditional rehab exercises. The therapist holds a but (Read more...)
iSchemaView’s RAPID CTA for Brain Angiography Imaging
iSchemaView, of Redwood City, California, won FDA clearance for its RAPID CTA imaging software for CT angiography. The package helps to visualize and analyze brain vasculature, including highlighting areas of lower than normal vessel density and providing 3D tools such as rotation and zoom to give a better idea of the relevant anatomy. Product page (Read more...)
New Technique to Measure Brain Blood Flow Using Light
Researchers at the University of California, Davis have developed a new method to measure blood flow in the brain using light. The method could provide a cheaper and more robust way to assess patients with traumatic brain injuries or stroke. The technique is based on the principle that shining a laser light through someone’s skull […]
Noninvasive Brain Tumor Biopsy Using Focused Ultrasound
Unlike many other tumors, ones found in the brain are usually too dangerous to take biopsies of. Now the researchers at Washington University School of Medicine in St. Louis came up with a revolutionary new way of using focused ultrasound to get tumors to release biomarkers that can then be spotted using blood samples. Thanks to […]
Tiny Wireless Optical Implant for Neural Control
Researchers in Japan have developed a tiny optical implant, no bigger than the width of a coin, that could be used to change neural behavior. The researchers can implant the device several centimeters into the body, and then activate it externally using infrared light. The device could make it easier for researchers to identify the […]
