Abstract: A computer system includes a client-side presentation layer processor; a server-side service layer component including at least one application programming interface (API) controller, at least one repository pattern processor, and a data layer processor; and a back-end layer component comprising at least one structured query language (SQL) server and a cache, wherein the client-side presentation layer processor interprets conversational modes directed to dialogues programmed in the computer system.

Abstract: An exemplary aspect includes a computer system that has a client-side presentation layer processor; a server-side service layer component comprising one or more API controllers, at least one repository pattern processor, and a data layer processor; and a back-end layer component comprising at least one SQL server and a cache. In various exemplary embodiments: (a) the presentation layer processor comprises one or more controllers; (b) the one or more API controllers provide application security and authentication; and (c) the data layer processor comprises at least one data access component.

Abstract: A method and apparatus for assisting right ventricle function of the human heart is described. A catheter having three longitudinally spaced balloon elements is inserted into the blood vessels adjacent the heart such that the first and third balloon elements are disposed in the superior vena cava and the inferior vena cava, respectively, and the intermediate balloon element in the right atrial chamber. The superior vena cava and the inferior vena cava are simultaneously occluded by inflation of the first and third balloon elements and, after occlusion, the atrial chamber is pressurized, by inflation of the intermediate balloon element, to urge blood flow through the tricuspid valve into the right ventricle. The first and third balloon elements are then deflated to allow blood flow to resume through the respective vessels and, thereafter, the intermediate balloon element is deflated to allow the atrial chamber to fill with blood. The cycle is repeated periodically at the heart rate.
