The Asporto // Heart Preservation Device is a portable thermoelectric cooler for transporting the donor heart to heart transplant recipients.  The device consists of a microcontroller with touch-screen display, insulated container, peristaltic pump, AC to DC converter and a sterile disposable kit. The Asporto microcontroller has been upgraded to software version 5.02.  The completely new software allows the microcontroller to have better usage of memory-mapped pages for fault-tolerant and reliable continuation following power interruptions.  The new software takes advantage of a multi-tasking operating system which optimizes touchscreen, display and pump operations.
