1. A user-wearable infusion pump system, comprising:
- a pump including;
a disposable cartridge configured to contain a medicament, the disposable cartridge including a cartridge housing having a front surface and a rear surface and a coupling recess defined in a bottom surface of the cartridge housing, the bottom surface extending between the front surface and the rear surface; and
a drive unit configured to cause medicament in the cartridge to be delivered to a user wearing the pump, the drive unit including a drive unit housing having a front surface and a rear surface and a drive mechanism having a drive end extending from the drive unit housing, andwherein the coupling recess in the cartridge is configured to be axially inserted onto the drive end of the drive mechanism with the cartridge in a first non-parallel orientation with respect to the drive unit and the cartridge is configured to be rotated around the drive end in a first direction with the drive end of the drive unit positioned within the coupling recess to lock the cartridge onto the drive unit in a second orientation wherein the front surface of the cartridge is aligned generally parallel to and coplanar with the front surface of the drive unit.

Abstract
A user-wearable patch pump system for delivery of insulin or other medicament can include a patch pump having a reusable drive unit and a replaceable and refillable cartridge. The cartridge can selectively attach to and be detached from the drive unit. The cartridge can initially be inserted onto the drive unit in a first orientation at an angle to the drive unit and then be rotated to align the cartridge with the drive unit and lock the cartridge in place on the drive unit to form the patch pump.
