Echolocation technologies can detect objects by measuring how long it takes sound to bounce off them. This is used to detect submarines underwater, but now to also measure a child’s breathing while delivering soothing, and sleep inducing, white noise. Next week, researchers from the University of Washington will be at the MobiCom 2019 confere (Read more...)

Medtronic Launches Evolut Pro+ TAVR System: Interview with Dr. Pieter Kappetein
Last month, Medtronic announced receipt of U.S. Food and Drug Administration (FDA) approval for and launch of the Evolut Pro+ TAVR (Transcatheter Aortic Valve Replacement) System to treat patients with symptomatic severe aortic stenosis. Aortic stenosis is characterized by stiff, often thickened aortic valve leaflets that struggle to open and close (Read more...)
FDA Clears geko Muscle Pump Activator to Prevent VTE
Venous thromboembolism (VTE) too often strikes bedridden patients in the hospital, and this is one of the main reasons that patients are put back on their feet as soon as possible. Inflatable wraps placed around the legs, which can raise the pressure, are a common way to prevent the condition. Now, a device called geko […]
iRhythm-Verily Partnership: Interview with iRhythm CEO Kevin King
iRhythm and Verily announced a partnership last month to “co-develop solutions intended to provide early warning, diagnosis and management for patients, particularly for those with silent or undiagnosed AF.” We spoke with iRhythm CEO Kevin King to understand how the two companies complement each other and how they can solve the problem (Read more...)
Light Therapy Device to Treat Carbon Monoxide Poisoning
Carbon monoxide (CO) is one of the most common substances that people are poisoned by. It has no smell and is invisible to the naked eye, but can cause severe damage to tissues and lead to death. Patients who have already suffered significant lung damage because of CO inhalation too often don’t respond sufficiently to […]
Gore CARDIOFORM ASD Cleared in Europe for Atrial Septal Defects
Gore won the European CE Mark for its GORE CARDIOFORM ASD Occluder, a device designed for percutaneous, transcatheter closure of ostium secundum atrial defects (ASDs). The occluder recently completed a clinical study involving 125 patients with ASD, ranging from 2 to 84 years of age, all of whom were successfully implanted with the GORE CARDIOFORM (Read more...)
Printing Custom Flexible Electronics Directly Onto Skin, Bandages, Medical Devices
Flexible electronics have the potential to help monitor, and even modulate, a number of physiological parameters. While stick-on heart monitors can be manufactured as one-size-fits-all, in applications such as electronic bandages that can monitor and treat a wound, it’s best to be able to create custom devices that suit each patient’s n (Read more...)
Disc Pump for Less Obtrusive Ambulatory Blood Pressure Systems
TTP Ventus, the UK-based developer of the Disc Pump, has recently begun working on a new application for this technology – ambulatory blood pressure systems. The company claims that the Disc Pump, which is a miniaturized, quiet, and highly efficient pump, could revolutionize ambulatory blood pressure measurements. At present, 24-hour blood pr (Read more...)
Hexoskin Shirt Proving Itself for Lung Function Measurement
A few years ago Hexoskin, a Canadian startup, announced the development of a sensor-packed t-shirt that can measure a number of physiological parameters in real-time. It’s novel because it doesn’t require the wearer to put on individual sensors and attach them to the skin, allowing common daily at-home and athletic activities to be perf (Read more...)
Nanoparticles Inside Samples of Mucus to Measure COPD Development
Management of chronic obstructive pulmonary disease (COPD) suffers not only from a lack of effective therapies, but also from an inability to track the disease’s progression. Spirometers that measure how much air patients can displace using their lungs are the “gold standard,” but that standard is pretty poor in helping to predict (Read more...)
New Chip for Microwave Imaging of Body
Today’s clinicians are limited to a few imaging modalities, primarily X-ray, CT, MRI, and ultrasound. Microwaves, in principle, can also be used as a useful way to look inside the body. Microwave radiation is non-ionizing, so should be safer than X-rays, but in practice microwave imagers, because of the electronics inside, have remained bulky (Read more...)
Apps for Healthcare Monitoring: Interview with Artem Petrov, CEO of Reinvently
Reinvently, a mobile app development company based in Palo Alto, California, has created a number of healthcare apps, including those which collect, collate, and display data from wearable medical devices. The combination of a wearable device and a mobile app allows clinicians to monitor their patients in real-time and identify issues before they b (Read more...)
Bathroom Scale Combined with ECG for At Home Heart Failure Monitoring
Electrocardiography (ECG) remains the primary clinical tool for evaluating heart function, but it has significant limitations when assessing heart failure. Ballistocardiography (BCG), which detects the slight physical movements the body experiences with each heart beat, has the potential to provide some of the information that ECG misses. The probl (Read more...)
Hydrogel Mimics of Heart Tissue to Study Cardiac Reshaping Following Aortic Valve Implantation
Transcatheter aortic valve replacement (TAVR) procedures have become a popular way of treating aortic valve stenosis, a condition in which the valve stiffens and worsens cardiac function. Following implantation of a prosthetic valve, the hearts of patients tend to undergo significant reconstruction around the treatment site, but the mechanics of th (Read more...)
Machine Learning Helps Predict Risk of Heart Failure in Patients with Diabetes
Researchers from Brigham and Women’s Hospital and UT Southwestern Medical center have developed a new machine learning algorithm that predicts the risk of heart failure hospitalization for people suffering from type 2 diabetes. Their work demonstrates that among 147 different demographic, clinical, and biological data, there is an important t (Read more...)
Early Bird, an Internal Bleeding Detector, Now Available In U.S.
Saranas, a Houston, Texas firm, is releasing its novel Early Bird bleeding monitoring system in the United States, following FDA de novo approval of the device. Intended for use during minimally invasive vascular procedures, the Early Bird helps to identify dangerous events such as ruptured or dissected vessels. Such incidents can result from using (Read more...)
Material to Repair Cardiac Tissue Damaged by Heart Attacks Passes First Clinical Trial
Ventrix, a spin-off company of the University of California San Diego, has developed a special hydrogel that can be injected into the heart to provide a platform for cardiac repair following a heart attack. The technology was just tested in humans for the first time as part of an FDA-approved Phase 1 clinical trial. Though […]
FDA Clears Siemens Artis icono Angiography Systems
Siemens Healthineers won FDA clearance for the ARTIS icono angiography systems that are designed for use in a variety of procedure types. The ARTIS icono 2D/3D biplane system is intended for neuroradiology and abdominal imaging while the ARTIS icono floor has a single fluoroscope and is designed for vascular, interventional cardiology, surgical, an (Read more...)
Flexible Vitals Sensors Made from Graphene Sensitized with Quantum Dots
At the ICFO – The Institute of Photonic Sciences, in Catalonia, Spain, researchers have come up with a way to use graphene to make flexible photodetectors to measure heart rate, blood oxygen concentration, and breathing rate. Additionally, the technology can also be used to measure UV levels coming from the Sun and to communicate the [&hellip (Read more...)
Smart Phyjamas for Monitoring Physiological Signals at Night
Researchers from University of Massachusetts at Amherst have developed a new smart pajama, dubbed Phyjama, that can track physiological signals during sleep. Their work demonstrates that the technology can reliably measure heart rate, breathing rate, and sleep position during the course of the night. One day, advances like this can be incorporated (Read more...)
