A system for infusing liquid to a body includes an infusion device, a network interface with a cell phone and wireless link and a network server system capable of communication with the infusion device through the network interface. The server system has access to a file of information specific to the controller for the infusion device. The infusion device includes a source of infusion fluid, a delivery port, a pump between the source of infusion fluid and the delivery port and a controller capable of programmable pump rate and sequence. A method for infusing liquid to a body includes controlling infusion using a programmable controller, establishing a file of information specific to the controller accessible to an extended area network server system and remotely transmitting commands to the controller. The information specific to the controller in the file is amended from a control terminal remote from the body. Operating instructions responsive to the updated information in the file are provided over an extended area network to a programmable two-way communication device. The device is capable of communication with the controller to forward operating commands. Requests for a bolus or a basal rate change are made through input to the two-way communication device which responds with commands transmitted over the wireless link to the controller consistent with the operating instructions from the server system. Network access through a monitoring terminal to the incidents of amending information specific to the controller is used for generating payments for the incidents of amending information specific to the controller accessed by the monitoring terminal.
