Fluoroscopic imaging and contour tracings of the heart surface
and CorInnova device in acute animal studies. Unlike previous epicardial assist
devices, the CorInnova device assists without inverting native heart curvature
(A,B). The device becomes intrinsically pneumatically coupled to the heart as
soon as the fluid component is filled (C) and free air is evacuated from the
chest, so that the heart is not ejected from the device during assist (D). This
allows the device to be implanted without invasive attachment methods, such as
suturing or vacuum). Reproduced with permission from [47] Moreno MR,
