Researchers at the Ohio State University Wexner Medical Center have developed a medical device that is intended to improve patient safety during cardiac ablation procedures to treat atrial fibrillation (AFib). At present, the esophagus can lie very near to the target tissue du...

Researchers at the University of Birmingham in the United Kingdom have developed a microfluidic device that mimics a human vein, including anatomical features such as valves, and physiological features such as pulsatile flow. The device is intended to make it easier to study p...

Researchers at Northwestern University and the University of Texas at Austin have developed a thin and flexible graphene “tattoo” that can be affixed to the outside of the heart, and which can monitor heart rhythms and apply corrective electrical impulses to treat arrhythmias....

Researchers at Linköping University in Sweden have developed a method whereby the body can ‘grow its own’ electrodes. The minimally invasive technique involves injecting a hydrogel that is laden with enzymes into target tissues. The enzymes interact with molecules that are pre...

Researchers at MIT have developed soft robotic heart replicas that closely match the anatomy of real people. The researchers used medical images of patient hearts to construct computer models that are suitable for 3D printing. Once printed with a soft material, the patient-spe...

Researchers at the University of Sydney in Australia have developed an electrospun blood vessel replacement. The material contains tropoelastin, a natural precursor for elastin, a key component of blood vessel walls. Elastin is present in concentric circles in natural blood ve...

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 inva...

The COVID-19 pandemic has put lung health firmly in our minds. For those with chronic lung diseases, such as asthma and COPD, an important way to keep track of lung health is to use a spirometer to measure how well air can move in and out of the lungs during forced breathing. ...

At the University of Minnesota, researchers have developed a soft robotic system that can ‘grow’ like a plant. The mechanism allows it to travel through difficult-to-access areas, such as the tortuous gastrointestinal tract or vasculature. The system works by extruding a liqui...

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 circulat...
