TIGERTRIEVER XL Cleared in EU to Remove Large Stroke Clots

Israel’s Rapid Medical has won European regulatory clearance to introduce its TIGERTRIEVER XL device for removing large ischemic stroke-causing clots from intracranial vessels. The company calls its line of devices “stentrievers,” as these look and operate similar to stents but can retrieve clots out of the body. The TIGERTRIEVER (Read more...)

Mechanically Stimulating Neurons Using Magnetic Nanodiscs

Electrical stimulation and chemical pharmaceuticals are the two ways that doctors and scientists routinely use to manipulate neural cells. Chemicals have their side effects, are slow to take effect, and are usually systemically delivered, while electrical stimulation usually requires invasive wires, is limited in its resolution, and is nearly impos (Read more...)

Micro-LEDs and Solar Panels Wirelessly Power Medical Implants

Researchers at the Gwangju Institute of Science and Technology in South Korea have developed a method to wirelessly power implanted devices using light. The technique involves a micro-LED patch to transmit light through the skin and a photovoltaic system on implanted devices that can turn this light into electricity. This technology could help rese (Read more...)

Robotic Transcranial Doppler for Stroke Detection and Risk Assessment in COVID: Interview with Diane Bryant, Neural Analytics

Emerging evidence suggests that COVID-19 patients are at a higher risk of stroke and promptly diagnosing and treating such patients is a priority in hospitals across the world. Moreover, identifying which COVID-19 patients are at increased risk of developing a stroke is also important, and may help with preemptive treatment and monitoring. The Luci (Read more...)

Go-2 Spinal Stimulator Helps Return Leg Function: Interview with Jan Öhrström, Chairman of the Board, GTX Medical

GTX Medical, a medtech company with offices in The Netherlands and Switzerland, has announced that it received Breakthrough Device Designation for the Go-2 system, an implant that provides targeted epidural spinal stimulation therapy for patients with spinal cord injuries. The device aims to allow such patients to regain leg motor function and neur (Read more...)

Easily Removable Surgical Tape to Seal Internal Wounds

Researchers at MIT recently developed an adhesive tape that allows surgeons to seal internal wounds and that can readily stick to slippery internal surfaces, as a potential replacement for sutures. However, the adhesive worked a little too well, and was difficult to remove or adjust without causing irritation or tissue damage. Now, the research tea (Read more...)

Battery-Free Neural Stimulator Powered by a Magnetic Field

Researchers at Rice University have developed an implantable neural stimulator that is both wireless and battery-free. The device is powered by an externally applied magnetic field and could be used as part of a system to treat a wide variety of diseases and conditions, including epilepsy, Parkinson’s disease, and chronic pain. At present, ba (Read more...)

M.Blue 2-in-1 Hydrocephalus Valve Unveiled

Aesculap, a part of B.Braun, and Miethke are releasing the M.blue adjustable gravitational hydrocephalus valve. The device features a valve that has both gravitational capability and a fixed differential pressure component, the only one of this kind. This allows the M.blue to automatically adjust the valve, within a certain range, based on the orie (Read more...)

Magnetic Tracking System for Flexible Surgical Robots

Researchers at the University of California San Diego have developed a magnetic tracking system for surgical robots to operate with dexterity within the body. The technology does not require patient or clinician exposure to radiation, and is much less expensive that pre-existing monitoring techniques. A magnet is embedded in the tip of the robot an (Read more...)

3D Printed Brain Implants Using Conductive Polymer Ink

Conductive polymers are a fascinating category of materials that are particularly exciting for biomedicine because of their flexibility, conductivity, and biocompatibility. Existing conducting polymers, though, can only be applied to other materials using traditional methods that are not suitable for 3D printing. Now, researchers at MIT have develo (Read more...)

SX-One MicroKnife Makes Carpal Tunnel Release a Minimally Invasive Procedure: Interview with CEO Dr. Darryl Barnes

Carpal tunnel syndrome is a fairly common diagnosis in the United States, affecting approximately three to six percent of adults. Symptoms include pain, numbness, and tingling along the thumb, index, and middle fingers. For severe or refractory cases, the best treatment is surgery. However, because open surgery requires anesthesia and many weeks of (Read more...)
