Biotricity’s Bioflux Live Cardiac Monitoring System FDA Cleared
Biotricity, a Silicon Valley firm, won FDA clearance for its Bioflux ECG monitoring system. The 3-channel device is used to help spot and identify cardiac arrhythmias. The mobile cardiac telemetry system transmits any likely cardiac events via its built-in 3G/4G cellular connectivity. The triggers can be set and changed remotely by the patient&rsqu (Read more...)
Proximity Tags Emit Radio Waves to Monitor Heart, Lungs, Blood Pressure
Contact-free measurement of vital signs is already a reality, but with a few important limitations some of which researchers at Cornell University may be able to overcome. Currently used devices typically require the patient to be in close proximity to the sensor, and they’re only able to measure the breathing and heart rates, along with [&he (Read more...)
DreamPort Sleep Solution for CPAP Therapy Without a Mask: Interview with Inventor, Bleep CEO Stuart Heatherington
Continuous positive air pressure (CPAP) therapy is impressively effective for treating obstructive sleep apnea, a condition that can lead to high blood pressure, increased chances of stroke, diabetes, and other health issues. But, while CPAP therapy works really well, it also has an incredibly poor rate of patient compliance. Very few, if any, pati (Read more...)
Masimo’s New rainbow Lite Sensors with Oxygen Reserve Index
Masimo is unveiling and releasing in Europe its new RD rainbow Lite SET sensors that measure the company’s proprietary Oxygen Reserve Index (ORi) and RPVi, a new and improved Pleth Variability Index (PVi) that relies on multiple wavelengths of light. This is on top of pulse oximetry capabilities. The technology allows for live fluid resp (Read more...)
SleepScore Max by SleepScore Labs: CEO Interview & Product Review
At the beginning of this year, Medgadget spoke with Colin Lawlor, CEO of SleepScore Labs about the company’s S+ non-contact sleep monitoring technology. Last month, we again heard from SleepScore Labs about their new SleepScore Max sleep monitoring system, an upgrade to the original S+. Since then, Medgadget was able to give the Sle (Read more...)
Heart Rate Variability, A Real-Time Method of Health Monitoring: An Interview with Jason Moore of Elite HRV
Elite HRV, creators of a heart rate variability (HRV) app and platform, has recently launched CorSense, their new HRV device, on Kickstarter that raised $100,000 within the first 48 hours. The company’s popular HRV app is available for download on your mobile device. HRV is a complex biomarker that acts as a comprehensive “check-engine (Read more...)
480 Biomedical Develops Bioresorbable Stent as Strong as Metal
With every heartbeat blood is carried through the arteries to provide organs with life-sustaining oxygen and nutrients. In patients suffering from diseases such as atherosclerosis, arterial blood flow can be severely restricted, limiting the delivery of oxygen and nutrients. To re-establish blood flow, surgeons may place a stent to mechanically re- (Read more...)
New Replacement Heart Valve Grows as Child Gets Older
Children born with congenital heart valve defects number in the thousands each year, yet there are simply no artificial cardiac valves available that were designed specifically for babies. Multiple heart surgeries have to be performed as the child outgrows successive implants. In addition, since the devices were never intended for children, they of (Read more...)
GO2SLEEP Wearable Sleep Tracker Capable of Detecting Sleep Apnea
A new startup company called SLEEPON has recently launched their crowdfunding campaign for their first product, GO2SLEEP, “the world’s smallest sleep apnea detection ring.” Sleep apnea is a condition where an individual’s breathing is interrupted during sleep, and this can lead to excessive daytime sleepiness, irritability, (Read more...)

3D Printing Helps to Implant Risky Transcatheter Mitral Valves
Transcatheter aortic valve implantations are now routine at a number of high-end hospitals around the world. Minimally invasive mitral valve replacements, on the other hand, are a lot more difficult and prone to post-op complications, and so are still a rarity. Yet, 60% of patients over 75 have mitral valve disease, and it’s an even [… (Read more...)
Computer Simulation Aims to Understand Arrhythmia-Induced Sudden Cardiac Death
Sudden cardiac death resulting from an arrhythmia is a rare and difficult to study disorder. Now researchers at Johns Hopkins University have developed a computer model of the heart specifically mimicking what happens to it prior to and during sudden cardiac death. The biomolecular simulation is already pointing to drug targets that should be looke (Read more...)
High-Tech Mobile Stroke Units Treat Patients Sooner
A stroke is one of the most time-critical medical emergencies. If not treated quickly, a patient can quickly deteriorate as brain cells die from a lack of oxygen. Doctors aim to begin treating stroke patients within an hour from the onset of symptoms, something that is often difficult to do when relying on conventional ambulances. […]
Apple Heart Study Launches: Anyone with Apple Watch Can Participate
Apple has now officially launched its previously announced Apple Heart Study with the release of the Heart Study app. In partnership with Stanford University, the Apple Heart Study aims to see if the Apple Watch can accurately identify arrhythmias with its heart rate tracking technology and notify users of possible atrial fibrillation. Unlike (Read more...)
Ultrasound Imaging Needle Set to Transform Heart Surgery
Researchers in London have published details of a revolutionary new cardiology needle capable of imaging the heart’s soft tissues from within. The team from University College London (UCL) and Queen Mary University of London (QMUL) used the new all-optical ultrasound imaging system for heart surgery in pigs, successfully capturing high-resolu (Read more...)
KardiaBand for The Apple Watch Records ECG, Detects Atrial Fibrillation
Watching the rhythm of your heart is getting quite a bit easier. AliveCor, the originators of the to-go ECG smartphone market, have announced FDA clearance of the KardiaBand single-lead ECG device for the Apple Watch. The device is capable of detecting atrial fibrillation, a common heart rhythm disorder that’s difficult to diagnose, and (Read more...)
Duke University Heart Patch Shows Promise in Repairing Cardiac Tissue Damage
Researchers at Duke University have developed an artificially-engineered patch consisting of fully functional human heart muscle tissue that can be used to repair damaged areas of the heart.
