1. A medical infusion pump system, comprising:
- a pump device including a drive system to dispense a medicine from a medicine-filled cartridge slidably inserted through an opening in the pump device, at least a portion of the drive system being in electrical communication with one or more electrical contacts of the pump device; and
a removable controller device having a user interface, the removable controller device being removably attachable to the pump device in a fixed relationship such that the user interface is arranged on a front face of the controller device opposite from the electrical contacts of the pump device, the controller device including one or more electrical contacts that engage the electrical contacts of the pump device when removably attached, wherein the controller device comprises a controller housing structure and the pump device comprises a pump housing structure, the controller housing structure being matable with a complementary portion of the pump housing structure so as to form a releasable mechanical connection including at least one of a snap fit engagement, a finger that engages a mating surface, a mating tongue and groove, and a friction fit connection.
