Abstract (en)
[origin: WO2013188199A1] An apparatus (1) for providing controlled delivery of a beneficial agent (2) is disclosed. In one embodiment, such an apparatus (1) includes a water chamber (8) and a filter to produce filtered water by removing impurities from water introduced into the water chamber. A water-transporting membrane transports filtered water from the water chamber (8) to an extraction chamber, thereby expanding the extraction chamber. The extraction chamber contains an osmagent that provides the driving force to pull the filtered water through the water-transporting membrane. As the extraction chamber expands, a dispensing chamber containing a beneficial agent (2) contracts. This causes the beneficial agent to be expelled through a port (10) in communication with the dispensing chamber. A corresponding method is also disclosed.
