Distribution servers and methods are disclosed for downloading data sets to patient devices. The server has a network interface circuit, a memory and a processing circuit. The memory receives a data set, the data set having parameters to be used by software on the patient devices to perform patient-related functions. The data set has a software version indicator for the data set. A processing circuit compares the software version indicator of the data set to a current software version of the patient device and determines that an inequality exists. Based on this determination, the server distributes the data set to the patient device.
