Abstract
Abstract The present invention relates to systems and methods for operating ambulatory medical devices, such as drug delivery devices. The pump includes the pump control system for activating a pumping mechanism wherein the pump control system includes a processor, a flash memory electrically interconnected to the processor for storing pump operation information, and a communications port electrically interconnected to the flash memory to permit transfer of the pump information into the flash memory from outside the pump. Communication with the pump can be through a computer system located locally or remotely with respect to the pump. The flash memory is utilized to initially program the pump electronically, or to reprogram the pump to change operation of the pump.
