ABSTRACT:
A total artificial heart, comprising a heart enclosure and an interior rigid septum attached at its periphery to the interior surface of the heart enclosure. This septum divides the heart into two separate pumping chambers corresponding to left and right ventricles. The septum has opposing nonplanar faces including a curved wave form with an "S" configuration to increase the surface area of the septum to be almost equal to the surface area of the interior surface of opposing chambers of the heart enclosure. This construction avoids overlapping of the attached pumping diaphragm with resultant stress and consequential failure. Also disclosed is a double lumen drive line which facilitates percutaneous entry of the required flow drive system.
