Abstract
Disclosed is a device for assisting the function of a heart that is collapsible to facilitate minimally invasive procedures. The cup-shaped device may be inserted into the chest cavity and deployed on the heart via a specially configured tube. The device comprises a cup-shaped shell expanded by a support cage disposed within the shell, and an elastic cup-shaped liner, together forming an inflatable cavity between the outer surface of the liner and the inner surface of the shell. Alternate application of positive and negative pressures to the cavity provides controlled, active, systolic and diastolic support to the heart.
