1. An apparatus for use with a dermis and a fluid cartridge, the apparatus comprising:
- a percutaneous cartridge port including a tubular wall, with an open and unobstructed first longitudinal end, a second longitudinal end, and an exterior, an end wall at the second longitudinal end, a resilient needle-puncturable septum at the end wall, and a porous region on the exterior of the tubular wall configured to promote soft tissue ingrowth, the porous region being located on the tubular wall such that a fluid cartridge located within the percutaneous cartridge port and at least partially within dermis that is ingrown into the porous region can be removed from the dermis by way of the open and unobstructed first longitudinal end and independently of the apparatus; and
an implantable operative portion, including a pump, operably connected to the percutaneous cartridge port.

17. An apparatus for use with a dermis, comprising:
-
means for percutaneously receiving and holding a fluid cartridge and resilient needle-puncturable septum such that at least a portion of the cartridge is within the dermis and the fluid cartridge can be removed from the dermis independently of the apparatus and without removal of the resilient needle-puncturable septum; porous material configured to promote dermis ingrowth carried on an exterior of the means for percutaneously receiving and holding a fluid cartridge; and an implantable operative portion that is operably connected to the means for percutaneously receiving and holding a fluid cartridge. - View Dependent Claims (18, 19)

20. An apparatus, comprising:
-
a housing member defining an interior surface, an interior volume and an opening with a size and a shape; a fluid transfer device, that does not include a reservoir, including an electromagnet within an electromagnet case that defines an exterior surface and a case outer perimeter, a fluid housing, that is not the housing member, mounted to the electromagnet case, defining a fluid housing outer perimeter, and having fluid lumens, a fluid inlet and a fluid outlet, an armature movable within the fluid housing, a piston mounted to the armature and movable within the fluid housing, and a barrier between the electromagnet and the armature; a housing cover, defining a cover outer perimeter that is greater than the case outer perimeter and the fluid housing outer perimeter and a size and a shape corresponding to the housing member opening, that is carried by the fluid transfer device such that at least a portion of the housing cover is located outside the fluid transfer device, is secured to the housing member at the opening, and includes a first side that faces the interior volume and a second side opposite the first side; the fluid transfer device defining first and second longitudinal ends and the housing cover being located between the longitudinal ends such that the electromagnet and the electromagnet case are located within the housing member interior volume, the fluid housing is located outside the housing member interior volume with the entire fluid inlet, and the entire fluid outlet is located on the same side of the cover; and a controller located within the housing member interior volume between the interior surface of the housing member and the exterior surface of the electromagnet case. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
