Abstract: A method and system are provided for a user interface. The system can include a plurality of information categories and option nodes organized into a hierarchy. A plurality of menu columns can be contained within a window. The menu columns can each be configured to display a portion of the plurality of categories and option nodes. A first scrolling control can be located adjacent to the plurality of menu columns and be configured to scroll the plurality of menu columns in a defined direction across the screen. A second scrolling control can be located adjacent on an opposite site of the plurality of menu columns. The second scrolling control can be linked to the first scrolling control to enable either scrolling control to be moved in the defined direction in order to scroll the menu columns and unused scrolling control simultaneously.

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.
