Leica’s Augmented Reality Surgical Microscope Combines Fluoroscopy and Natural Color Vision
Leica Microsystems won FDA clearance to introduce its GLOW800 augmented reality surgical fluorescence system for vascular neurosurgery. The system provides provides simultaneous, natural color view of the surgical field overlaid with real-time vascular flow, all with full depth perception and without any misalignment between the two images. Previously, surgeons had to switch between the two […]
Spinal Cord Epidural Stimulation Lets Paralyzed Walk Again
While paralysis is common following a serious spinal injury, it seems that many patients may be treated with a new therapy that has already proven to restore walking and standing in a few study volunteers. Researchers at University of Louisville in Kentucky, reporting in New England Journal of Medicine, combined spinal cord epidural stimulation with simultaneous […]
Paladin Carotid PTA Balloon with Embolic Protection Filter Cleared by FDA
Contego Medical, out of Raleigh, North Carolina, won FDA clearance for its Paladin carotid PTA (Percutaneous Transluminal Angioplasty) balloon catheter. The device, used to open up narrow arteries and to post-dilation of self-expanding stents, has a built-in embolic protection filter that traps any debris that may become dislodged and forced to flow downstream of the […]
Focused Ultrasound and Intranasal Drug Delivery for Brain Cancer Therapy
Researchers at Washington University in St. Louis have developed a new method to bypass the blood-brain barrier and deliver drugs to the brain, which could be particularly useful in difficult-to-treat brain tumors. The technique involves administering drugs through an intranasal spray, meaning that the drug can travel directly into the brain along the trigeminal and olfactory […]
Seizure Control Device Delivers Drugs Inside Brain
A collaboration between researchers at University of Cambridge in the UK and École Nationale Supérieure des Mines and INSERM in France has developed a device that can sense electrical brain activity and deliver a pre-loaded drug dose in response. It has already been tried on mice undergoing seizures, releasing a native brain chemical that is […]
Two New Penumbra Catheters to Suck Out Stroke Causing Clots
Penumbra, a company famous for its suction-based stroke clot removal devices, is releasing what it says is its “most advanced technology,” the Penumbra JET 7 and Penumbra JET D Reperfusion Catheters. The devices work with the company’s Penumbra ENGINE system provides the vacuum aspiration that’s necessary to pull a thrombus from inside a vessel in the […]
RightEye Vision Tests for Eyes and Brain: Interview with Co-Founder and CSO Dr. Melissa Hunfalvay
Medgadget recently demoed RightEye’s vision tests with Dr. Jennifer Kungle, a provider at The Center for Vision Development, and worked with the beta version of the company’s at-home EyeQ Trainer. It was a great experience that this editor would recommend for patients going through vision rehabilitation or individuals seeking a more vivid understanding of their […]
Draper’s Wireless Brain Implant to Make New Therapies Possible
Draper, an engineering firm in Cambridge, MA, has developed a tiny wireless neuromodulation device that may be small enough to implant into the interior of the cranium right against the brain. Current brain stimulators are placed, like pacemakers, under the skin in the chest, with electric leads reaching out through the vasculature into the brain. […]
Training Athletes’ Dynamic Vision with System Originally Designed to Detect Concussions
SyncThink is a company known for making eye tracking devices that can help to diagnose brain concussions. Their FDA-cleared EYE-SYNC technology is already being used by a number of university sports programs, as well as by major hospitals. Now the same technology is being adapted to help athletes in demanding sports to improve their dynamic […]
Vagus Nerve Stimulation Highly Effective at Treating Drug Resistant Depression
Drugs have been the go-to therapy for psychiatrists treating depression, but implantable neurostimulators have been making substantial impact lately. A national study headed by a team from Washington University School of Medicine in St. Louis wanted to find out how well this drug-free technique can control serious depression. The team evaluated about 600 patients, all […]
7D Surgical’s Machine-Vision Image Guidance for Cranial Surgery FDA Cleared
7D Surgical out of Toronto, Canada won FDA approval to introduce its Machine-vision Image Guided Surgery (MvIGS) system for cranial surgery. The system uses cameras and computer vision algorithms to map the external anatomy without requiring any markers to be placed on the body. Typically, fiducial markers are placed on the skin that identify specific spots […]
RightEye Vision Tests with Contextualized Results: Review and Interview
Many readers will be familiar with visiting an eye doctor to receive a range of exams to evaluate attributes such as visual acuity, color blindness, eye movement, depth perception, or the presence of glaucoma. These vision tests focus on the eyes themselves and how well they are functioning. Perhaps less familiar to our readers are […]
Hospital Introducing HoloLens Augmented Reality into the Operating Room
Alder Hey, an important children’s hospital in Liverpool, England, is working on integrating Microsoft HoloLens augmented reality technology into its operating theaters. The HoloLens is a headset that is able to overlay digital images onto a person’s field of view, essentially mixing virtual reality with the real world. The hospital partnered with Black Marble, a Microsoft partner […]
Genotype-Specific Microparticle Treatment for Brain Cancer
Researchers from Harvard and MIT have developed microparticles that can treat a specific genetic subtype of glioma, a brain cancer. The microparticles slowly release a drug that specifically targets cancer cells that rely on a particular enzyme. During surgery to remove the brain tumor, clinicians can conduct a rapid (30 min) genetic test on a […]
TIGERTRIEVER 13, World’s Smallest Clot Retriever for Strokes, Cleared in Europe
Rapid Medical, based in Yokneam, Israel, won European regulatory approval to introduce its TIGERTRIEVER 13, the narrowest clot retriever now available for use in treating ischemic stroke. The device can be used in vessels as small as 1 millimeter in width and up to a maximum of 2.5 mm, where larger retrievers would be appropriate. It works […]
EMBOTRAP II Clot Retriever Now Saving People from Ischemic Strokes in U.S.
CERENOVUS, a part of Johnson & Johnson, is reporting that its EMBOTRAP II clot retriever has been used commercially for the first time in the U.S. to reverse an ischemic stroke.
