Tozuda Head Impact Sensor: Interview with Jessie Garcia, Tozuda CEO and Founder
Tozuda, a company based in Philadelphia, has developed a head impact sensor that can be attached to a sports helmet, such as those worn by football or hockey players, and which will indicate if a dangerous impact has occurred. The sensor undergoes a simple color change if an impact that is powerful enough to cause […]
Pill-Sized Chemical Heater for Point-of-Care Diagnostic Tests
Researchers at the University of Toronto have developed a miniaturized chemical heater that can precisely heat biological samples during diagnostic tests, but does not require electricity or any specialized equipment to work. The low-cost technology is based on the exothermic reaction that occurs when lithium encounters water, and the precise shape (Read more...)
VitalConnect Introduces Remote Arrhythmia Detection Using VitalPatch
In a world where cardiovascular diseases are the leading cause of death (with an estimated 17.9 million annual deaths globally, according to the WHO), the need to accurately and reliably monitor patients following cardiac procedures is ever-growing. This need is highlighted by the frequency of complications that occur following such procedures. For (Read more...)
Stain and Label-Free Microscopy Enables Imaging of Extracellular Vesicles
Researchers at the Beckman Institute of the University of Illinois at Urbana–Champaign have developed a method that employs ultrashort laser pulses to visualize extracellular vesicles in tissue samples without using stains or labeling compounds. An increase in the number of these small vesicles is known to be associated with cancer, whereby c (Read more...)
Improved PCR Flu Diagnostic for Pandemic Response: Interview with Chris Hole of TTP
TTP, a technology company based in Melbourn, UK, is developing a handheld PCR (polymerase chain reaction) diagnostic device that can rapidly detect influenza viruses, and one day other viruses, in samples of nasal mucus. The company claims that the system, which uses a high speed version of traditional RT-PCR (reverse transcription polymerase chain (Read more...)
Brain Implant Powered and Controlled by Magnetic Fields
Neural implants may provide treatment options for a wide variety of ailments, including Parkinson’s and epilepsy, but such devices have to work for long periods of time in a very difficult environment inside the cranium. One challenge is providing power to brain implants and another is communicating with such implants to control their functio (Read more...)
Lensless Microscopy Chip for Diagnostic Applications
Researchers at the University of Connecticut have developed a lensless microscope that allows an observer to enjoy an enormous field of view. Instead of a lens, the system relies on a diffuser that lies between the object being imaged and the camera sensor. This novel technology could greatly help clinicians to assess diagnostic tissue samples [&he (Read more...)

VOCSN 5-in-1 Portable Ventilator: Interview with Chris Kiple, CEO of Ventec
Ventilators are used by patients who lose lung function due to complications from a variety of diseases such as spinal cord injuries, COPD, stroke, pneumonia, and ALS. In addition to dealing with a debilitating situation, patients tend to be hooked to several machines that perform mechanical ventilation, oxygen delivery, cough assist, suction, and (Read more...)
Beddr SleepTuner: Medgadget’s Review of The Novel Sleep Tracker
Sleep trackers are no stranger to Medgadget. Over the years, we’ve looked at various gadgets that monitor your “ZZZ’s” from your wrist, on your mattress, and even within your pajamas. With a growing interest in methods of maximizing work and life productivity (particularly among millennials), an ever-increasing number of fin (Read more...)
Magnetoencephalography Machine to Map Brain Activity FDA Approved
Compumedics, a company based outside of Melbourne, Australia, has won FDA approval for its Orion LifeSpan Magnetoencephalography (MEG) single Dewar system. MEG is a promising imaging technique that uses superconducting quantum interference devices (SQUIDs) to detect ionic currents produced by excited neurons, giving a window into the live activity (Read more...)
Surfacer FDA Cleared for Unusual Dialysis Central Venous Access
The right internal jugular vein is typically the ideal access point for performing hemodialysis via a central venous catheter. Yet, in close to half of patients there’s an obstruction that makes this either a serious challenge or an impossibility. Now, a device called the Surfacer Inside-Out Access Catheter System has been cleared via the FDA (Read more...)
Scientists Make Organs Transparent
Whole organs are difficult to study in minute detail, as they have to be sliced into extremely thin sections to map out their interior. CT and magnetic resonance imaging help to an extent, but researchers at the Helmholtz Zentrum München, Ludwig Maximilians University Munich, and Technical University of Munich in Germany have managed to make [ (Read more...)
Smart Jumpsuit Tracks Infant Movements to Spot Neurodevelopmental Disorders
Researchers at the University of Helsinki have developed a smart jumpsuit for children as young as five months, that tracks body movement in great detail. The system may allow clinicians to identify neurodevelopmental disorders in children more easily, potentially allowing for earlier intervention and support for such children. At present, assessin (Read more...)
COSMED Q-NRG+ Metabolic Monitor Cleared in U.S.
The FDA has cleared COSMED’s Q-NRG+ metabolic monitor, a device that uses indirect calorimetry to measure a patient’s energy demands. Q-NRG+, made by COSMED, a company based in Rome, Italy, can help to prevent malnutrition in seriously ill patients without relying on traditional, and often inaccurate, measures such as age, gender, weigh (Read more...)
QyScore Analyzes MRIs for Biomarkers of Brain Diseases
Qynapse, a firm headquartered in Paris, France, won FDA clearance for its QyScore software that analyzes brain MRIs for biomarkers of central nervous system diseases. It’s intended to help diagnose and monitor diseases such as Alzheimer’s, Parkinson’s, and multiple sclerosis, though it doesn’t do it on its own. The technolog (Read more...)
World’s First Portable MRI Cleared by FDA
Magnetic resonance imaging (MRI) has revolutionized medicine, but MRI scanners are so demanding that access to them is still a challenge. MRI machines typically require specially built rooms with magnet quench vent pipes, entry systems that check people for metals attracted to magnets, and specific protocols to ensure safety. Patients, therefore, h (Read more...)
MiSight 1 day Contacts to Slow Myopia: Interview with Michele Andrews of CooperVision
CooperVision, a contact lens developer based in San Ramon, California, recently received FDA approval for its MiSight 1 day contact lens.
