A research team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and Seoul National University has developed a new electric mesh device that can be wrapped around the heart to deliver electrical impulses and improve cardiac function in experimental models of heart failure. The new method improves heart function and treats dangerous arrhythmias by compensating for damaged cardiac muscle and enabling healthy heart muscle to work more efficiently.

The new mesh device is made up of nanowires embedded in a rubber polymer that can conform to the unique three-dimensional anatomy of each individual heart. The mesh essentially wraps around and “hugs” the heart, and delivers electrical impulses to the ventricular myocardium, or heart muscle. The device shows that the mesh integrates both structurally and electrically with the myocardium following heart attack, acting as a substructure of the heart.
