Embodiments of the present invention involve a refill apparatus comprising at least one pump, a plurality of reservoirs, a plurality of reservoir fluid channels each associated with one of the reservoirs, a plurality of valves, each having a cracking pressure, for fluidically sealing the reservoir fluid channels and the outlet fluid channel, an outlet fluid channel fluidically connected to the reservoir fluid channels, and a needle having a lumen in fluid communication with the outlet fluid channel. A parameter such as a pressure level is monitored, and one or more pumps and various ones of the valves are actuated in accordance with a protocol comprising a sequence of steps whereby fluidic pathways are opened between different ones of the reservoirs and the needle in a washing and filling sequence, each of the steps being associated with an expected pressure level.

Drug refill applicator system and method of use

An implantable device has an outer shell that includes an aperture through the housing of the device and, spanning the aperture, a membrane structure permeable to gas but not to liquid. In this way, excess gas may be vented from the device. The membrane and aperture are designed to discourage or even prevent tissue ingrowth.
