主权项

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.
