Abstract (en)
[origin: WO0025842A1] A ventricular assist device (10) is designed to assist a heart to pump blood by applying uniform pressure to a majority portion of an exterior ventricular surface of the heart. A specially configured bladder (14) is utilized to apply the pressure, and is prefabricated in an inflated, unfolded configuration to reduce wall stresses in the bladder when inflated. The inflatable bladder may also comprise a plurality of individually inflatable compartments (18). The compartments may have different dimensions to complement the dimensions of corresponding segments of the heart, and may be inflated at different times or at different pressures based upon the determined needs of the heart.
