Steerable Catheter to Navigate Tortuous Blood Vessels in Brain

A team at University of California San Diego invented a way to make steerable catheters that can more precisely navigate the tortuous architecture of the brain vasculature. The device was bioinspired by delicate structures found in nature, including flagella and insect legs, and uses principles from soft robotics to create a hydraulic steering syst (Read more...)

Inflatable Prosthetic Hand with a Sense of Touch

Researchers at MIT and Shanghai Jiao Tong University created an inexpensive robotic hand intended for use by upper limb amputees. The device is more like a soft robot than previous robotic prostheses, and includes inflatable components and pneumatics, making it lightweight and inexpensive. Excitingly, the hand is equipped with sensors and provides (Read more...)

Tiny Neural Sensors for Brain Computer Interfaces

Researchers at Brown University have developed wireless micro-implants that can function as a network of neural sensors and stimulators in the brain. The research team has dubbed their creation “neurograins,” which are intended to be implanted in the brain in large numbers. When inside, they can transmit data to an external communicatio (Read more...)

Neuromodulation for Lennox-Gastaut Syndrome: Interview with Martha Morrell, M.D., CMO of NeuroPace

NeuroPace, a medtech company based in California, has developed the RNS system, an implantable neuromodulation device for focal drug-resistant epilepsy. The system continuously monitors brain activity and then responds appropriately to target the seizure source in the brain for personalized seizure prevention. The company reports that the stimulati (Read more...)

Wearable Sensor Monitors Myoclonic Jerks

Researchers at the University of Eastern Finland have developed a wearable surface electromyography and three-dimensional accelerometry system that can measure the occurrence and severity of myoclonic jerks, which are sudden muscle movements experienced by patients with progressive myoclonic epilepsy. The muscle jerks can be unpleasant, but can als (Read more...)

Pressure-Sensing Glove to Aid in Stroke Recovery

Researchers at MIT created a sensing glove that can detect small pressuref changes along its surface when a wearer grasps something. The glove is threaded with tiny pressure sensors, which are studded with micropillars that create changes in an electrical signal when they bend and deform. This provides an incredibly sensitive measurement of tactile (Read more...)

Breath Test Predicts Treatment Regimen for Epilepsy Drugs

Anti-seizure medication must be tailored for individual patients, as the difference between a therapeutic dose and a toxic one is quite small. Now, researchers at the University of Basel in Switzerland have developed a breath test that can rapidly provide information on the optimal drug treatment approach for epilepsy patients. Their test provides (Read more...)

Wireless Light Implant for Optogenetics Without Skull Damage

Researchers at the University of Arizona have overcome a major limitation of optogenetics with their wireless and battery-free implant that can shine light through the skull. The small device, which is implanted under the skin, could provide a light source for optogenetics that doesn’t require damage to the skull or brain. While optogenetics (Read more...)

Oscillating Magnetic Field Shrinks Glioblastoma Tumor

At the Houston Methodist Neurological Institute, researchers have developed a device that generates a magnetic field and used it to successfully shrink a glioblastoma tumor in a patient volunteer. The device is worn on the head each day during treatment, and uses an oscillating magnetic field to disrupt biochemical processes in cancer cells. While (Read more...)

Blood-Brain Barrier on a Chip for Neuro Drug Testing

Researchers at the KTH Royal Institute of Technology in Stockholm, Sweden, engineered a blood-brain barrier on a chip using human-derived stem cells. The device closely mimics the blood-brain barrier and allows the researchers to study its function and the effect of drugs without having to use experimental animals. By incorporating sensors, the chi (Read more...)

Inflatable Neurostimulator for Minimally Invasive Pain Control

Researchers at the University of Cambridge created a spinal stimulation device that can help to control severe pain. Unlike existing technologies, which require invasive surgery for implantation, the new device can be delivered using a needle. Once implanted, the device unfurls and inflates in place to provide extensive coverage during spinal cord (Read more...)

Drinking Straw Device for Hiccups Treatment

Researchers at the University of Texas Health Science Center at San Antonio have developed a device to treat hiccups. The drinking straw-like device allows a user to apply forceful suction to draw water into it, with subsequent swallowing triggering both the phrenic and vagus nerves, which helps to relieve hiccups. The treatment may be the [&hellip (Read more...)

Brain Stimulation Lets User Feel Robotic Arm

Researchers at the University of Pittsburgh have demonstrated that providing direct sensory feedback into the brain dramatically enhanced an impaired patient’s control of a robotic arm. The arm was operated through a brain-computer interface, but the system also included brain implants in an area of the brain responsible for sensory feedback. (Read more...)

Light-Responsive Hydrogel to Fill Cerebral Aneurysms

Researchers at Pohang University of Science & Technology (POSTECH) in Korea have developed a new technique to treat cerebral aneurysms. Described in journal Advanced Materials, the treatment involves using a catheter to deliver an alignate hydrogel that is crosslinked in place within the aneurysm using light. The hydrogel is not degradable and (Read more...)

Sugar Coated Brain Implants

Researchers at McGill University in Canada have developed a method to create and deliver brain implants that are a similar in consistency to the brain itself, which is a soft gelatinous tissue. The delicate silicone implants are created using sugar molds and delivered using a sugar needle, and their delicate consistency helps to ensure that [&helli (Read more...)
