Abstract: An expandable device comprising a plurality of expandable cells. The cells may be bistable cells or other types of cells that are expanded from a contracted position towards an expanded position. Additionally, the cells may be combined with locking mechanisms to hold the structure in an expanded position.

Abstract: A needle cutting device (1) for cutting a needle (6) from a mount in a syringe (8) comprises cutting apparatus (220) and a container for storing cut needles. The container includes an aperture (4) having an axis along which a needle, but not a mount associated with the needle, may be introduced into the container. The cutting apparatus has first and second cutting surfaces (222, 223), at least the first cutting surface (222) being located at an end of a flexible blade member (226). The first cutting surface (222) is movable relative to the second cutting surface (223) in a direction transverse to the axis of the aperture by movement of at least part of the blade member in a direction substantially parallel to the axis of the aperture to move the first cutting surface relative to the second cutting surface in order to nip and cut a needle within the aperture.

Abstract: The present invention provides a simple form of nozzle assembly for use in generating sprays from a fluid, which comprises a first member having one or more nozzle outlets, one or more fluid inlets and one or more channels connecting them formed by electrical or chemical etching or other processes which selectively remove material from one face of the said member; and a second member co-operating with the said first member to provide a wall of said outlets, inlets or channels to form the fluid flow paths for the nozzle assembly.

Abstract: A nozzle assembly for use in atomizing and generating sprays from a fluid. The nozzle assembly includes two members, each with generally planar surfaces, that are joined together. A first set of channels is formed in the generally planar surface of a first one of the members to form, in cooperation with the generally planar surface of the second of the members, a plurality of filter passageways. A plenum chamber is formed in the first member. The plenum chamber is in fluid communication with and downstream of the plurality of filter passageways. A second set of channels is formed in the generally planar surface of the first member to form, in cooperation with the generally planar surface of the second member, a plurality of nozzle outlet passageways. These nozzle outlet passageways are in fluid communication with the plenum chamber.

Abstract: A nozzle assembly for use in atomizing and generating sprays from a fluid. The nozzle assembly includes two members joined together. In one of the two members are formed one or more nozzle outlets, one or more fluid inlets, and a plurality of channels that form filter passageways. The nozzle outlets discharge fluid jets that impinge on one another to thereby atomize the fluid. Alternatively, an impact element or a vortex-generating structure can be used in the nozzle outlet to atomize the fluid. Methods are also provided for producing the nozzle assembly by forming the inlets, outlets, and/or channels through electrical or chemical etching or other processes that selectively remove material from at least one face of a nozzle assembly member.
