Belt Monitors Heart Failure Patients

Researchers at Florida Atlantic University have developed a belt that can monitor heart failure patients for signs of disease progression. The wearable device measures heart rate, thoracic impedance, electrocardiogram, and motion, all of which can provide information on a heart failure patient’s status and potentially enable early detection o (Read more...)

Camera Measures Blood Pressure with Quick Look

At the University of South Australia, researchers designed a system that allows them to measure a patient’s blood pressure with a camera. The camera visualizes the patient’s forehead and focuses on two regions in particular to optically determine photoplethysmographic signals that AI algorithms then convert to blood pressure data. The r (Read more...)

Monitoring Congestive Heart Failure Through Speech: Interview with Tamir Tal, CEO of Cordio Medical

Cordio Medical, a medtech company based in Israel, has developed HearO, an app that can assist in monitoring congestive heart failure. The technology is based on the phenomenon whereby congestive heart failure patients demonstrate changes in their voice as their disease progresses or in advance of disease exacerbation. This includes lung sounds, su (Read more...)

Device Measures Hemoglobin More Accurately in Dark Skin

Researchers at the University of Texas at Arlington, in collaboration with Shani Biotechnologies, a local firm, have created a point-of-care device that can accurately measure hemoglobin levels and perform pulse oximetry in individuals with dark skin. At present, methods to determine hemoglobin levels at the point of care, such as pulse oximetry, a (Read more...)

Battery-Free Light-Powered Pacemaker Now a Reality

Researchers at the University of Arizona have developed a battery-free light-powered pacemaker that uses optogenetic stimulation of cardiomyocytes to achieve heart pacing. With conventional pacemakers, the leads of the device are anchored into the wall of the heart, using invasive hooks or screws. Small electrical shocks are then sent through the e (Read more...)

Low Temperature Graphene Coating for Enhanced Wearables

Researchers at Caltech came up with a technique to coat flexible electronic circuits with graphene to enhance their durability on folding, as well as to improve their resistance to sweat (in the case of graphene-coated gold) and their conductivity. The method could enhance the flexible electronics that are employed in many medical wearables. The ap (Read more...)

Smartphone Camera Measures Blood Oxygen

At the University of Washington a research team has developed a smartphone system that can measure blood oxygen levels. The technology uses the camera and flash of the phone to take the measurement, and the system is so easy to use that it may be well suited for at-home use. A person presses their finger […]

Silicone Heart Models Heart Failure

Scientists at the Royal College of Surgeons in Ireland and partners at the National College of Art and Design in Dublin have developed a silicone heart model that is intended to model heart failure with preserved ejection fraction. The device, which represents a ‘mock circulatory loop’, includes a simulated version of the left atrium an (Read more...)

Assessing Heart Function and Fluid Status with Cardiac Scales: Interview with John Lipman, CEO, and Corey Centen, Founder, Bodyport

Bodyport, a medtech company based in San Francisco, developed the Bodyport Cardiac Scale, a set of weighing scales that can non-invasively assess fluid status and heart function. The scales can detect these signals through the feet when a patient steps onto the device. The technology is intended to be convenient and requires only 20 seconds [&helli (Read more...)

Biosynthetic Trilayered Ventricle Pumps Blood

Biomedical engineers at the University of Toronto have developed a method to create a small-scale biosynthetic left ventricle that can pump blood within a bioreactor. While the construct is too small to act as replacement for a human heart, it could lead to full-sized biosynthetic organ transplants. In fact, the man-made ventricle already showed a (Read more...)

Artificial Ventricle Mimics Helical Muscle Fibers

Researchers at Harvard developed a technique that lets them recreate the helical arrangement of cardiac muscle fibers within the heart ventricles in a bioengineered construct. The breakthrough could pave the way for artificial bioengineered hearts. The researchers used a technique called Focused Rotary Jet Spinning (FRJS) that allows them to deposi (Read more...)

Magnetic Steering System for Guidewires

Percutaneous coronary intervention is an incredibly useful technique to minimally invasively investigate and treat cardiac issues, such as blockages in the coronary arteries, but it requires a significant amount of skill to perform safely and effectively. Manipulating a guidewire through the tortuous vasculature is not for the faint hearted, with t (Read more...)
