This could be the battery-free solution for pacemakers

A new energy storage system charges itself using ions from inside the human body – providing an exciting alternative to traditional batteries used in pacemakers, according to researchers at the University of California at Los Angeles and the University of Connecticut. Researchers at the universities developed a bio-friendly energy storage system called a biological supercapacitor;

Apple Watch detects atrial fibrillation using built-in technology

The Apple Watch can automatically detect atrial fibrillation (AF) using its built-in heart rate sensor and artificial intelligence, according to a new study. The research used a deep neural network that was based on photoplethysmographic (PPG) sensors that are frequently found in smart watches. When paired with an artificial intelligence-based algorithm, Apple Watch’s heart rate

‘No-touch’ heart bypass surgery reduces strokes

A recent study from the University of Sydney and Sydney Heart and Lung Surgeons has shown that a new “no-touch” beating heart bypass surgery technique has reduced post-operative stroke by 78%. The procedure, known as an OPCABG, also reduced post-operative mortality by 50% compared to traditional coronary artery bypass grafting. It reduced renal failure by

Could wireless signals help diagnose diseases?

Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory (CSAIL) has developed a wireless device that is the size of a small painting and could help diagnose cognitive decline and cardiac disease – all through wireless signals. The device, deemed WiGait, measures the walking speed of people with 95 to 99% accuracy using wireless

This new ‘smart shirt’ can monitor your vital signs

Holst Center researchers have created a smart shirt that uses state-of-the-art printed electronics technology to track vital signs. IMEC, a Belgian research and development and innovation hub that specializes in nanoelectronics and digital technologies, developed a medical-grade electrocardiogram (ECG) with breathing rate and breathing depth. Researchers at Holst in the Netherlands used the IMEC ECG

How Boston Sci is getting drug-eluting stents and balloons into legs

Boston Scientific officials think they have a leg up when it comes to bringing drug-eluting technology to bear on peripheral artery disease. That’s because the medical device giant has decades of experience with balloons and drug-eluting stents used around the heart. When it comes to treating the narrowing arteries in the legs and thighs, Boston

This smartphone app accurately screens for heart arrhythmia

Maybe a selfie can help after all. The Media Lab at Massachusetts Institute of Technology has developed a mobile app that uses a smartphone’s camera to detect signs of a heart arrhythmia. Evaluating a person’s facial expressions is one of the ways to determine if someone is experiencing a stroke. The MIT app measures and

How deep learning could change diagnostic imaging forever

Computational imaging is a passion for Fabein Beckers. As the CEO of Arterys, Beckers thinks he can revolutionize how doctors on a global scale work with imaging diagnostics. In that vein, Beckers and his team launched Arterys, which enables clinical visualization and accurate quantification of blood flow inside the body. It measures 7 dimensions of data (3 in

Growing human hearts: The answer is spinach leaves?

We could someday be using spinach to grow human hearts, thanks to new research from the Worcester Polytechnic Institute, the University of Wisconsin-Madison and Arkansas State University. One of the problems that researchers have faced is how to create a vascular system that can deliver blood deep into developing tissues. There hasn’t been much success

The top medtech stories of early 2017

The new Trump administration and Republican Congress – and all the accompanying change and uncertainty –is the major story for the medical device industry. But there are many other medtech stories worth noting from the first quarter of 2017. There was an FDA warning over Abbott’s Absorb bioresorbable stent, a continued spate of M&A deals, a

MR Solutions offers MRI imaging solution for cardiologists

MR Solutions has created 9.4 tesla cryogen-free, preclinical scanners that are ideal for use among cardiologists. The new helium-free Flexiscan and Powerscan scanners are powerful and have multi-modality by integrating PET and SPECT capabilities. The Flexiscan doesn’t need a specialist to operate and can be used by running pre-defined settings. The SPECT image system works by

Disposable lead wires market to reach nearly $1 billion

Use of disposable lead wires is growing globally, and sales are expected to reach $999.4 million by 2025. As reported by Grand View Research, a key factor driving growth is the rising incidence of hospital-acquired infections. North American hospitals are by far the largest sector of disposable lead wire adopters. Care centers with remote monitoring

9 cardiology breakthroughs you need to know

Cardiology breakthroughs couldn’t come soon enough because heart disease is the No. 1 killer of men and women in the U.S. About 610,000 Americans die of heart disease per year, and an additional 735,000 Americans suffer from a heart attack. The statistics terrify. High blood pressure, high cholesterol and smoking are some of the top

Nanoengineers 3D-print biomimetic blood vessel networks

University of California San Diego researchers have 3D-printed a functional blood vessel network that they believe could someday be used in artificial organs and regenerative medicines. The team’s work was published in Biomaterials. Previous work in the field has yielded simple and costly structures, the researchers said, that are not capable of integrating with the body’s own

Aortic stenosis test for open heart surgery is inaccurate

An approved exercise test that determines whether people with aortic stenosis need open heart surgery has only 60% accuracy, according to a new study by the University of Leicester. Cycling on a stationary bike typically determines whether a person needs surgery. If the patient becomes breathless while cycling, it is typically recommended to have valve
