1. An apparatus for use with 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, an inlet and an outlet; and
a delivery/manifold tube, having an outer perimeter and a longitudinal axis defining an axial direction, and including a manifold portion and a delivery portion, the manifold portion including a first fluid lumen that is operably connected to the fluid transfer device inlet, a second fluid lumen that is operably connected to the fluid transfer device outlet, and a lumen-free portion that is between the first and second lumens and is lumen-free in a cross-section which is perpendicular to the longitudinal axis and extends to the entire outer perimeter of the delivery/manifold tube at the lumen-free portion, that prevents all flow through the cross-section of the delivery/manifold tube in the axial direction during operation of the pump and that prevents direct flow from the first fluid lumen to the second fluid lumen during operation of the pump, and the delivery portion including a delivery lumen that is operably connected to the second fluid lumen.

14. An apparatus for use with 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, an inlet and an outlet; and a delivery/manifold tube defining a longitudinal axis and including a manifold portion with a first fluid lumen, a second fluid lumen, and a lumen-free region that is located between the first and second fluid lumens such that the entire first fluid lumen is longitudinally offset along the longitudinal axis from the second fluid lumen and direct flow from the first fluid lumen to the second fluid lumen is prevented, and a delivery portion with a delivery lumen that extends from the second fluid lumen; wherein the implantable operative portion is positioned relative to the percutaneous port such that the pump and the delivery portion of the delivery/manifold tube will be located subcutaneously when the percutaneous port is located percutaneously; and wherein the percutaneous port, the implantable operative portion, and the delivery/manifold tube are configured and arranged relative to one another such that, in response to operation of the pump, fluid flows from the first fluid lumen to the implantable operative portion inlet and from the implantable operative portion outlet to the second fluid lumen. - View Dependent Claims (15, 16)
