1. A method of operating a medical infusion pump system, the method comprising:
- inserting a medicine cartridge in a pump housing structure of the pump device so that an exterior wall of the medicine cartridge slidably engages an interior wall of the pump housing structuretransmitting electrical energy, from a first battery in a pump device including a drive system to dispense a medicine from the pump device, to a second battery in a removable controller device that is removably attached to and electrically connected to the pump device; and
intermittently transmitting electrical energy from the second battery in the removable controller device to at least a portion of the drive system of the pump device,wherein the first battery has a greater energy density than the second battery and provides energy to charge the second battery over a period of time.

Abstract
Some embodiments of a medical infusion pump system include a pump device and a removable controller device. When the pump device and the removable controller device are removably attached to one another, the components may provide a portable infusion pump unit to dispense medicine to a user. In particular embodiments, the removable controller device includes a user interface to readily provide information, for example, about the operation of the pump.

10. A method of operating a medical infusion pump system, the method comprising:
-
inserting a medicine cartridge in a pump housing structure of the pump device so that an exterior wall of the medicine cartridge slidably engages an interior wall of the pump housing structure; attaching a removable controller device to a pump device in a fixed relationship so that the controller device is electrically connected to the pump device, the pump device including a drive system to dispense a medicine from the pump device; transmitting electrical energy from a first electrical power source in the pump device to a second electrical power source in a removable controller device, wherein the first power source has a greater energy density than the second power source and provides energy to charge the second power source over a period of time; and transmitting electrical energy from the second power source in the removable controller device to at least a portion of the drive system of the pump device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of operating a medical infusion pump system, the method comprising:
-
transmitting electrical energy, from a first battery in a pump device including a drive system to dispense a medicine from the pump device, to a second battery in a removable controller device that is removably attached to and electrically connected to the pump device, wherein the pump device comprises a pump housing structure that defines a space to slidably receive a medicine cartridge that extends a majority of the length of the pump housing structure, and wherein the drive system of the pump device comprises a flexible piston rod that is incrementally advanced toward the medicine cartridge when the medicine cartridge is received by the pump housing structure; and intermittently transmitting electrical energy from the second battery in the removable controller device to at least a portion of the drive system of the pump device, wherein the first battery has a greater energy density than the second battery and provides energy to charge the second battery over a period of time. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
