of the present invention can be collapsed and inserted through a small incision when the device of the present invention is depressurized it does not interfere with the heart the support component can be progressively actuated to left shift the end diastolic pressure volume relationship edpvr when pressurized during systole the device of the present invention morphs to end systolic shape and thus assists the heart to change from ed configuration to es configuration pressurization of the device of the present invention does not dislodge the heart and stroke work sw can be restored to normal in a shock model the device of the present invention takes on a rigid cup like shape i e structurally supported cavity when it is pressurized and this naturally draws the heart into the device u2014 such that suturing to the heart is not required for example it is very difficult to pull a water balloon out of a cup when they are placed inside of a bag with the air evacuated i e like a closed chest after air in the mediastinum is removed the heart and device are pneumatically locked in a co axial configuration this feature was proven by fluoroscopy of device assist when pressurized the air filled bladders are easily visible on flouro and it is evident that the heart is not displaced by.
