  • Patent number: 8777011
    Abstract: A package for storing an aerosolizable pharmaceutical formulation comprises a capsule adapted to contain the aerosolizable pharmaceutical formulation, and a moisture barrier around the capsule. The moisture barrier comprises a material that is resistant to moisture passage, whereby the moisture barrier reduces the amount of moisture in contact with the aerosolizable pharmaceutical formulation so that the aerosolizable pharmaceutical formulation may be aerosolized when the capsule is opened. In one version, the moisture barrier comprises a metal.

  • Patent number: 8061222
    Abstract: The invention provides systems and methods for measuring the mass of a substance. In one method, energy is applied to a substance and a response resulting from the application of energy as measured. The mass of the substance is then determined based at least in part on the measured response.

  • Publication number: 20090032427
    Abstract: A receptacle (100) includes a holder (5) forming a cavity (25) that holds a pharmaceutical (110), a lid (15), and adhesive (17) that forms a bond (20) between the holder (5) and the lid (15). As an example, the bond (20) has a shape that includes a protrusion (30) that facilitates removal of the lid (15) from the holder (5). A kit (60) includes a plurality of containers containing powder including amphotericin B and pharmaceutically acceptable excipient. The kit (60) also includes an aerosolization apparatus (1100) and instructions. As an example, the pharmaceutical composition is made from panicles including amphotericin B having a mass median diameter less than about 3 ?m, such as from about 1.1 ?m to about 1.9 ?m.

  • Publication number: 20050236296
    Abstract: A carry case is provided for use by a diabetic patient. The carry case comprises a first compartment sized and shaped to contain an aerosolization apparatus, a second compartment sized and shaped to contain one or more receptacles for use in the aerosolization apparatus, and a third compartment sized and shaped to contain a glucose meter. In one version, the receptacles contain an aerosolizable pharmaceutical formulation comprising insulin. The carry case allows the patient to conveniently monitor and regulate the patient's glucose level.

  • Patent number: 6042966
    Abstract: The subject invention provides a battery pouch or container which is highly resistant to shorting. This electrical protection is produced by a folding of the packaging laminate such that the cut edge of the laminate is physically removed and electrically protected from the electrode tab which protrudes from the battery pouch. In one embodiment, the cut edge of the film is folded away from the electrode tab. In a preferred embodiment, the laminar packaging material includes a convex flap of material where the electrode traverses the package. The convex flap is folded away from the electrode tab without wrinkling or distorting the pouch shape. In an alternate embodiment, an intervening layer of insulative material is placed between the cut edge and the electrode tab.

  • Patent number: 6040085
    Abstract: The subject invention discloses apparatus and methods to provide compression of an electrochemical cell independent of atmospheric pressure. One aspect of this invention is directed towards a lithium ion cell assembly which is surrounded by a layer of material under tension, so that the material applies pressure which compresses the cell to enhance contact between the anode, separator, and cathode layers. Specifically, a heat shrink material (material which reduces in size, or contracts in at least one dimension of a three-dimensional conformation, due to the application of heat) is provided about a laminar battery and shrunk in situ to provide a battery package. Another embodiment of this invention is directed towards a lithium ion cell asembly in which a sealed package contains both the battery and a spring element. The spring element within the package applies pressure to the battery to compress it and improve contact between the anode, separator, and cathode layers.

  • Patent number: 5670272
    Abstract: In order to maintain electrical contact between the anode, cathode and electrolyte layers in an electrochemical cell, a layer of material under tension is wrapped around the cell so that the material compresses the layers together to ensure sufficient electrical contact. Alternatively, a metal, foam or inflatable gas spring is employed in a housing structure containing the electrochemical cell to apply a compressive force to achieve the same result.

  • Patent number: 5534368
    Abstract: A battery module has a current collecting spacer positioned between two sides of a folded laminate including a first electrode layer. Top and bottom opposite electrode layers, of opposite polarity from the first electrode layer, are formed on the top and bottom of the folded laminate such that, when the opposite electrode layers and the folded laminate are compressed around the spacer, each opposite electrode layer forms, with a portion of the folded laminate, a substantially planar surface. A method for making the battery module is also described.
