Abstract
In one embodiment, an implantable drug pump device comprises: a port for transferring infusate to the device; a collapsible reservoir for storing infusate received via the port; the port extending through a housing of the device and into the reservoir; the reservoir comprising a bottom surface that moves in relation to an amount of infusate in the reservoir; the bottom surface being connected to an extensible structure; and wherein when the reservoir is at least partially emptied of infusate, the reservoir is in a substantially collapsed state with the bottom surface being disposed above an interior surface of the port and the extensible structure surrounds a portion of the port that extends into the housing.
