Magnets and Nanoparticles for On-Demand Leaky Vessels

Scientists at Rice University have developed a method to open gaps between the endothelial cells that line blood vessels using a magnetic field and iron oxide nanoparticles. The gaps close by themselves after the researchers remove the magnets. They hope that the concept could be used to help deliver larger therapeutic molecules like proteins to [& (Read more...)

Edwards SAPIEN 3 Cardiac Valve FDA Approved for Mitral and Aortic Valve-in-Valve Procedures

Edwards Lifesciences received FDA approval for its SAPIEN 3 transcatheter prosthetic heart valve to be used for valve-in-valve procedures. Indicated for placement within both the aortic and mitral valves in patients at risk of undergoing open heart surgery to remove an existing valve, the SAPIEN 3 can reside within a previously implanted biopr (Read more...)

Sentinel Cerebral Protection System for Preventing Strokes During Transcatheter Valve Repairs Cleared by FDA

While transcatheter aortic valve repair (TAVR) procedures can help avoid open heart surgeries in many fragile patients, there is a substantial risk that embolic debris is released from the calcified valves. The brain is particularly in danger, as the dislodged material can block blood vessels feeding it and result in strokes. Claret Medic (Read more...)
