1. An apparatus for use with a dermis and a fluid cartridge, comprising:
- a percutaneous port including an interior configured to receive the fluid cartridge;
an implantable operative portion, including a fluid transfer device with a pump, operably connected to the percutaneous port and positioned relative to the percutaneous port such that the pump will be located subcutaneously when the percutaneous port is located percutaneously;
a cartridge sensor configured to sense movement of the fluid cartridge relative to the percutaneous port; and
a controller, operatively connected to the cartridge sensor, that determines whether or not the fluid cartridge has been rotated relative to the percutaneous port.
