Arteriosclerosis, the stiffening and thickening of arterial walls, is a major driver of heart attacks and strokes, but it is difficult to monitor continuously in daily life. Most current diagnostic tools rely on hospital equipment, short snapshots of vascular health, […]
Heart disease remains one of the most difficult conditions to monitor outside a clinical setting because most diagnostic tools require patients to lie still, remove clothing, and wear specialized sensors for only a few minutes at a time. This creates
Studying and treating heart disease has long been constrained by the limitations of metal electrodes, which can damage tissue, introduce contamination, and fail to replicate the soft, dynamic environment of the beating heart. Researchers at the University of California, Irvine
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

Strokes often begin with tiny blood clots forming inside damaged or irregular arteries, but it has been hard to watch those first moments in action. A University of Sydney team has built small, patient‑specific models of blood vessels that let

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 »
A team at the École Polytechnique Fédérale de Lausanne (EPFL) has introduced MagFlow, an ultraminiaturized neurovascular microcatheter designed to reach the smallest and most complex blood vessels in the human body. Unlike conventional catheters that rely on guidewires and manual
