Abstract: A miniature pump including a first chamber, a second chamber, a deformable membrane provided within the second chamber that divides the second chamber into first and second sub-chambers, the second sub-chamber defining a reservoir configured to contain liquid to be dispensed, a passage that connects the first chamber to the first sub-chamber, and an outlet in fluid communication with the reservoir, wherein pressurized fluid within the first internal chamber flows through the passage and into the first sub-chamber to compress the deformable membrane and cause liquid contained within the reservoir to flow out from the reservoir through the outlet and wherein the deformable membrane does not generate significant restoring forces when it is deformed and, therefore, will not return to its initial undeformed shape unless the reservoir is refilled.

Abstract: In one embodiment, a fluid storage device includes a rigid outer housing that defines a septum cavity, a reservoir cavity, and a channel that extends between the two cavities, the outer housing further defining an outlet in fluid communication with the reservoir cavity, a septum provided within the septum cavity, the septum being made of an elastic polymer and facilitating refilling of the fluid storage device, and a thin, collapsible membrane that does not generate significant restoring forces when it is deformed as fluid is drawn from the reservoir cavity and, therefore, does not completely or partially return to its initial non-deformed shape even if the outlet of the device remains open after doses are administered.

Abstract: In one embodiment, a peristaltic micropump comprising a substrate having a first side and a second side, a microtube that extends across the first side of the substrate, and multiple pump actuators formed on the first side of the substrate and positioned adjacent to the microtube at discrete, spaced positions along the length of the microtube, wherein the micropump is configured to sequentially actuate the pump actuators so as to create peristaltic action that drives fluid contained in the microtube along the length of the tube.
