After some extensive searching, I conclude that the application is not available for public downloading. This is bundled with a machine after it's purchased. The old company that developed the application is now known as Natus and they also provide medical devices and machines.
To obtain more information (as they recommend on the official website), contact the developers/manufacturers: http://www.natus.com/index.cfm?page=products_1&crid=223
