1. A method of using an infusion pump system, the method comprising:
- inserting a pre-filled medicine cartridge into a pump device, the pump device defining a greatest dimension extending in a longitudinal direction and a space that extends along a longitudinal axis in the longitudinal direction to slidably receive the pre-filled medicine cartridge; and
removably attaching the pump device with a controller device so that the pump device is arranged adjacent to the controller device in a fixed relationship, wherein removably attaching the pump device with the controller device comprises mating a first electrical connector of the pump device with a second electrical connector of the controller device, the controller device being electrically connected to the pump device when in the fixed relationship, and the pump device housing a battery-powered actuator that mechanically moves in response to electrical signals from the controller device to the pump device,wherein the pump device is removably attached to the controller device by guided movement of the pump device relative to the controller device in the longitudinal direction such that the pre-filled medicine cartridge received in the pump device is guided over a first end of the controller device and toward a second opposite end of the controller device.

Abstract
Some embodiments of an infusion pump system includes a controller device that is configured to removably attach to a pump device in a manner that provides a secure fitting, an overall compact size, and a reliable electrical connection. In particular embodiments, the controller device can be secured to the pump device in a generally side-by-side arrangement. The compact size can enhance the discreteness and portability of the infusion pump system.

23. A method of using an infusion pump system, the method comprising:
-
inserting a pre-filled medicine cartridge into a pump device, the pump device defining a space that extends along a longitudinal axis in a longitudinal direction to receive the pre-filled medicine cartridge; removably attaching the pump device with a controller device so that the pump device is arranged adjacent to the controller device in a fixed relationship, wherein removably attaching the pump device with the controller device comprises mating a first electrical connector of the pump device with a second electrical connector of the controller device, the controller device being electrically connected to the pump device when in the fixed relationship, wherein the pump device is removably attached to the controller device by guided movement of the pump device relative to the controller device in the longitudinal direction such that the pre-filled medicine cartridge received in the pump device is guided over a first end of the controller device and toward a second opposite end of the controller device; and causing a release member to momentarily shift away from a locking position during guided movement of the pump device relative to the controller device in the longitudinal direction, wherein the release member comprises a latch that is shifted in a lateral direction away from the pump device during guided movement of the pump device relative to the controller device in the longitudinal direction, wherein the latch is biased to return to the locking position to thereby retain the pump device and the controller device in the fixed relationship. - View Dependent Claims (24, 25, 26)

31. A method of using an infusion pump system, the method comprising:
-
inserting a medicine in a longitudinal direction into a space of a pump device that extends a substantial majority of a longitudinal length of the pump device, wherein the pump device houses;
a battery-powered actuator that mechanically moves in response to control signals transmitted from a controller device, and a piston rod having a leading end that is advanced in the longitudinal direction in the space to dispense the medicine;removably attaching the pump device with the controller device so that the pump device is arranged adjacent to the controller device in a fixed relationship, wherein removably attaching the pump device with the controller device comprises mating a first electrical connector of the pump device with a second electrical connector of the controller device, the controller device being electrically connected to the pump device when in the fixed relationship so as to transmit the control signals to the pump device, wherein the pump device is removably attached to the controller device by sliding the pump device along a longitudinal guide member of the controller device to provide guided movement of the pump device relative to the controller device in the longitudinal direction. - View Dependent Claims (32, 33, 34, 35, 36)
