Heart Model Simulates Mechanical Load on Cardiac Tissues
Researchers at Carnegie Mellon University, along with collaborators in the Netherlands, have developed a heart model consisting of engineered cardiac muscle tissue that is attached to an elastic material. The design allows the team to mimic the...

Battery-Free Wireless Pacemaker Dissolves Post Treatment
Researchers at Northwestern University and collaborators have developed a temporary cardiac pacemaker that dissolves away in the body into harmless byproducts. The technology avoids the need for leads penetrating the skin as well as follow-up...

Spray-On Hydrogel to Prevent Post-Surgery Adhesions
Researchers at University of California San Diego have developed a spray-on hydrogel that forms a protective coating on tissue surfaces, such as the surface of the heart. The new material is intended to prevent the formation of adhesions, where...

Cardiac Organoids Self-Organize to Mimic Human Heart
Researchers at the Austrian Academy of Sciences have developed the most realistic cardiac organoids to date. The tiny structures self-organize from pluripotent stem cells to form a hollow chamber that can beat. The method to create the...

Wireless Sensor Measures Deep Tissue Oxygen Levels
Researchers at the University of California, Berkeley have developed an ultrasound-powered implantable sensor that can measure oxygen levels in tissues deep within the body and transmit these data to an external device. The technology could be...

Heart Patch Helps Grow New Vessels Post Myocardial Infarct
Researchers at the Pohang University of Science & Technology (POSTECH) in South Korea have developed a hydrogel patch system that allows for sophisticated sequential release of growth factors that stimulate angiogenesis. The sequential cascade...

Tendon-Inspired Sutures Protect Fragile Tissues
Researchers at McGill University in Canada have developed bioinspired sutures that mimic the structure of human tendons. The gel-covered sutures are slippery and tough, reducing the damage caused by conventional sutures when used on soft...
