Peptide Particles Ferry Drugs Across Blood-Brain Barrier

Most drugs, genetic materials, and other therapeutic agents are very difficult to use inside the brain because of the blood-brain barrier. There have been attempts to use ultrasound and microbubbles to create temporary passages through the barrier, including as a possible therapy for Alzheimer’s disease, but this is approach is not easy or id (Read more...)

3D Microenvironments to Grow Brain Tumors in Lab

Clinical researchers are constantly thwarted by the inability to quickly and easily try new therapies in tumors and other disease targets. Tumors within the brain are particularly hard to study because of the difficulty with access and the incredible fragility of nearby tissues. Researchers at Tufts University have just developed a way to create an (Read more...)

Exoskeleton Walks to Brain’s Commands

Powered exoskeletons are used to help people with lower limb paralysis get on their feet and allow post-stroke patients to recover faster. They’re pretty impressive devices, but people who are severely disabled, including those suffering from tetraplegia, can’t get much benefit from them. Now, a team of researchers in France has succeed (Read more...)

New Imaging Technique Reveals Deep Tumors, Helps Attack Them

Tumors deep inside the body can be very difficult to spot, track, and study. The brain, being surrounded by a thick skull, is particularly challenging to image using light, so MRI and CT are currently the go-to imaging modalities when looking at deeply seated tissues. Now, researchers at Stanford University are reporting the development of [&hellip (Read more...)

Galen Microsurgery System Eliminates Hand Tremor

Galen Robotics, a company based in Baltimore, Maryland, has been working on incorporating robotics and microsurgery. Microsurgery requires a steady hand and a great deal of patience, something that robots can be pretty good at. By creating an innovative interface between the surgeon’s hands and a specially designed robot, Galen’s techno (Read more...)

FDA Clears Siemens Artis icono Angiography Systems

Siemens Healthineers won FDA clearance for the ARTIS icono angiography systems that are designed for use in a variety of procedure types. The ARTIS icono 2D/3D biplane system is intended for neuroradiology and abdominal imaging while the ARTIS icono floor has a single fluoroscope and is designed for vascular, interventional cardiology, surgical, an (Read more...)

Injectable Hydrogel for Transcatheter Intravascular Embolization: Interview with Dr. Rahmi Oklu, Founder of Obsidio

Obsidio Inc., a medical device company based in Columbia, South Carolina, has developed an embolic hydrogel (called a gel embolic material: GEM) designed to be delivered minimally invasively through a clinical catheter for blood vessel occlusion. Applications include controlling blood flow in vascular injuries and aneurysms, reducing tumor blood su (Read more...)

Edwards ForeSight Brain Oxygenation Sensors FDA Cleared to Pair with Hemosphere Monitor

Edwards Lifesciences won FDA clearance to integrate its ForeSight brain tissue oxymetry sensors with the HemoSphere monitoring platform. While the clearance is really for a connecting cable, the capability allows anesthesiologists to monitor the oxygen saturation of the brain during surgeries and to correlate it with hemodynamic parameters in real- (Read more...)

Sensor Monitors Brain Aneurysms Post Treatment

Aneurysms within the brain are extremely dangerous, although there are therapies available such as stents and blood flow diverters. Even after treatment, a cerebral aneurysm can continue developing and how it heals cannot be predicted. Monitoring a treated vessel deep within the brain would provide physicians with the ability to act in situations t (Read more...)
