Abstract
A device for performing minimally invasive closed chest heart massage comprises a support having a plurality of curved, deployable struts, optionally carrying a sheet or inflatable bladder for engaging the pericardium. The struts are delivered to the space between the pericardium and the posterior rib cage in a radially collapsed configuration and deployed radially outwardly with minimum advancement in the axial direction.
