Flexible Microprobe for Neural Interfacing

Researchers at the University of California San Diego have developed a tiny neural probe that is approximately one fifth of the width of a human hair. The probe is flexible and can be implanted for extended periods without aggravating the immune system, in part because of its small and unobtrusive profile. Its miniature size means […]

Zoom POD for Sterile Field Clot Capture: Interview with Daniel Davis of Imperative Care

Imperative Care, a medtech company based in California, created the Zoom Stroke Solution, a complete system for the mechanical removal of clots in patients with ischemic stroke. The system includes an access catheter, aspiration catheters, a powerful pump, and the latest addition, the Zoom Pod, a clot filter that is positioned within the sterile fi (Read more...)

Flexible Brain-Computer Interface Array for Better Contact

Researchers at the University of California San Diego have created a brain-computer interface array featuring microneedles affixed to a flexible backing. The design allows the array to better conform to the undulating surface of the brain, permitting better contact and improved signal recording across a wide area. The technology represents an upgra (Read more...)

Artificial Neurons and Synapses from Printed Transistors

Researchers at Linköping University in Sweden have created artificial neurons and synapses using organic electrochemical transistors that can be printed onto plastic foil in their thousands. The printed structures can conduct both electrons and ions, helping them to mimic the action potentials generated in biological neurons. So far, the Swedi (Read more...)

Funky Helmet Enhances MRI Brain Scans

A team of engineers and radiologists at Boston University created a helmet that can dramatically improve MRI scans of the brain. The device consists of a series of magnetic metamaterial resonators that significantly boost MRI performance. This results in crisper images that can be obtained at twice the speed of a normal scan. The breakthrough [&hel (Read more...)

MRI-Guided Magnetic Seeds Heat and Destroy Tumors

Scientists at University College London have developed a highly targeted anti-tumor treatment. The approach involves guiding ferromagnetic thermoseeds to the site of a tumor using the magnetic fields generated by an MRI scanner. The magnetic seeds can then destroy the tumor through localized heating that is induced by an MR-compatible thermoablativ (Read more...)

Thought-to-Text Brain-Computer Interface: Interview with Florian Solzbacher, Chairman of Blackrock Neurotech

Blackrock Neurotech, a medical technology company based in Salt Lake City, created a suite of brain-computer interface systems with the goal of empowering patients to have increased independence and quality of life. This latest technology aims to restore written communication in patients who have difficulties in this regard, such as those affected (Read more...)

Wireless Photoelectric Implant for Optogenetics Research

Scientists at Ecole Polytechnique Fédérale de Lausanne in Switzerland created a wireless photoelectric implant that allows them to activate or suppress certain neurons in the mouse spinal cord. The flexible implant is controlled through Bluetooth and contains miniaturized LEDs that emit red light, which helps to avoid absorption and r (Read more...)

Laser-Assisted Bioprinting of Neurons

A team at Concordia University in Montreal have developed a technique called Laser-Induced Side Transfer (LIST) that allows for bioprinting of neurons. Low energy laser pulses are directed at a capillary containing a cell-laden bioink, resulting in microbubbles that eject a microjet of the ink onto the substrate below. The technique appears to be f (Read more...)

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...)

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...)

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...)
