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...)

Neurons Grow on Crosslinks of Carbon Nanotubes

Carbon nanotubes have a host of interesting properties. They are biocompatible and electrically conductive, so have been investigated as a possible material for growing nerve tissues. To make carbon nanotubes cooperate as desired, novel forms are required and researchers at SISSA (International School for Advanced Studies) and University of Trieste (Read more...)

Wireless Brain Implant Controls Mice Using Drugs and Light

Optogenetics is a quickly evolving field that allows scientists to activate specific neurons using bursts of light. The technique may help to uncover the basis of neurological diseases and how to tame them. Using optogenetics to assess how different drugs affect the central nervous system may offer a powerful new scientific tool. To that end, [&hel (Read more...)

Implanted Electrodes Improve Powered Prosthetic Arms

Today’s conventional powered prosthetic arms usually have a few built-in electrodes that make contact with patient skin. These are good enough to open and close a simple claw, but for more nuanced control of prostheses with multiple degrees of freedom and individual fingers, a better approach is required. Implantable electrodes can gather a g (Read more...)

New Biomaterial Improves Brain Cancer Survival in Rats

Researchers from the University of Nottingham have developed a new biomaterial that delivers chemotherapies to treat brain cancer. Their work demonstrates that their biodegradable paste led to increased survival compared to controls, and that half of all rats in a study were clear of any cancer as confirmed by laboratory tests. This exciting develo (Read more...)

Generating Hallucinations Using Optogenetics

About a decade ago, Karl Deisseroth of Stanford University developed a technology called optogenetics. It allows scientists to stimulate individual nerve cells using light beams within the brains of live and moving animals. Now, this technology has been used to generate visual hallucinations within lab mice, causing them to act as though the things (Read more...)

New Nanoparticles Help Spinal Cords to Heal Following Injury

When people damage their spinal cords, a lot of the long-term consequences often stem from the body’s overreaction to the injury. That’s because the blood-brain barrier protecting the spinal cord becomes compromised and overly aggressive immune cells flood in. Now, a team from the University of Michigan has developed a way of using intr (Read more...)
