Pacemakers require periodic battery replacement, a process that can be risky, costly, and burdensome for patients who depend on long‑term cardiac rhythm management. Leadless intracardiac pacemakers reduce complications compared with traditional chest‑implanted models, but their batteries still occupy more than […]
Pacemaker Nanogenerator Harvests Heartbeat Energy To Power Itself Read More »
Heart disease remains difficult to study because conventional laboratory models cannot reproduce the complex motion, internal structures and disease mechanics of the human heart. Researchers at UNSW Sydney have developed a soft robotic model of the left side of the
Severe heart failure leaves patients with few meaningful options because damaged heart muscle cannot regenerate and the heart gradually loses its ability to pump blood effectively. A new approach out of the University Medical Center Göttingen (UMG) and the University
New Heart Patch Therapy Shows Clinical Benefit for Severe Heart Failure Read More »
Researchers at Washington State University have created a 3D‑printed heart model that can beat, pump fluid, and mimic the mechanical behavior of real cardiac tissue, offering surgeons a more realistic way to practice complex procedures before entering the operating room.
Researchers from Waseda University in Japan have developed a new adaptive vascular stent that can automatically deploy at body temperature using 4D printing and a shape memory polymer composite. The stent is made from a polycaprolactone based material whose thermal
Researchers at Harvard University John A. Paulson School of Engineering and Applied Sciences and the Department of Stem Cell and Regenerative Biology have developed soft electronic cardiac patches that integrate nanoelectronics with stem cell–derived heart tissue. The goal is to

Researchers at Texas A&M University have introduced a biodegradable microneedle patch designed to help the heart heal after a heart attack. Heart attacks deprive cardiac muscle cells of oxygen, causing them to die. The body responds by forming scar tissue,
Biodegradable Microneedle Patch Heals the Heart After MI Read More »
A new implantable patch developed by MIT engineers could dramatically improve recovery after heart attacks by delivering a sequence of therapeutic drugs directly to damaged heart tissue. Designed for use during open-heart procedures such as bypass surgery, the patch mimics
Heart Patch Uses Timed Drug Delivery to Heal Damage After Heart Attack Read More »
Designing a mechanical heart that mimics the natural flow of blood is no small feat. At Linköping University in Sweden, researchers have used advanced imaging techniques to study blood movement inside a pulsating artificial heart. This work is helping engineers
Imaging Blood Flow Helps Improve Artificial Heart Design Read More »
Heart disease remains one of the leading causes of death worldwide, and researchers continue to search for better ways to repair damaged cardiac tissue. A new breakthrough from the University of California, Irvine offers a promising solution: a light-responsive biomaterial
