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 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...
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....
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,...
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...
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...
SQI Diagnostics, a medtech company based in Canada, is developing the TORdx LUNG Test. The technology is intended to assist clinicians in assessing donor lungs in their suitability for transplantation. At present, clinicians typically assess...
Paragonix Technologies, a medtech company based in Massachusetts, created the SherpaPak, an FDA organ transportation device that is intended to keep donor organs safe and viable on their journey to a transplant recipient. As the viability of a...
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...
Researchers at the University of Texas at Austin created a nanocarrier for stem cell factor, a regenerative cytokine. The nanotechnological approach renders the treatment much safer, as previous attempts to use stem cell factor as a...
Researchers at the Technical University of Munich in Germany have developed a technique to create heart valve scaffolds that can mimic the variable mechanical properties of the real thing. The researchers used a method called melt...
