  • Patent number: 7585493
    Abstract: An article for use in an aerosol device, for producing an aerosol of a drug composition is disclosed. The article includes a heat-conductive substrate having a surface with a selected surface area, and a drug composition film on the substrate surface having a selected film thickness of between 0.05 and 20 ?m. The film thickness is such that an aerosol formed by vaporizing the drug composition by heating the substrate and condensing the vaporized compound contains 10% or less drug-degradation product and at least 50% of the total amount of drug composition contained in the film. The selected substrate surface area is such as to yield an effective human therapeutic dose of the drug aerosol. Also disclosed are methods of making and using the article.

  • Patent number: 7513781
    Abstract: An improved heating element connector assembly includes an insulative, rectangular frame with a central opening, and a plurality of conductive terminals which are press fit into openings in the frame. The terminals are spaced apart from each other lengthwise of two opposing sidewalls of the frame, and pairs of terminals are aligned with each other between the two sidewalls. A plurality of conductive strips are held together in an assembly and the ends of the strips are interconnected along two spaced apart lines by carrier members that may be molded over the ends of the conductive strips. The carrier members extend down into cavities on the frame and terminals are pushed into the cavities to bear against the ends of the strips and effect an electrical connection between the terminals and the strips.

  • Publication number: 20080311176
    Abstract: The present invention provides novel condensation aerosols for the treatment of disease and/or intermittent or acute conditions. These condensation aerosols have little or no pyrolysis degradation products and are characterized by having an MMAD of between 1-3 microns. These aerosols are made by rapidly heating a substrate coated with a thin film of drug having a thickness of between 0.05 and 20 ?m, while passing a gas over the film, to form particles of a desirable particle size for inhalation. Kits comprising a drug and a device for producing a condensation aerosol are also provided. The device contained in the kit typically, has an element for heating the drug which is coated as a film on the substrate and contains a therapeutically effective dose of a drug when the drug is administered in aerosol form, and an element allowing the vapor to cool to form an aerosol. Also disclosed, are methods for using these aerosols and kits.

  • Publication number: 20040099266
    Abstract: A device for delivering a drug by inhalation is disclosed. The device includes a body defining an interior flow-through chamber having upstream and downstream chamber openings, and a drug supply unit contained within the chamber for producing, upon actuation, a heated drug vapor in a condensation region of the chamber. Gas drawn through the chamber region at a selected gas-flow rate is effective to form drug condensation particles from the drug vapor having a selected MMAD between 0.02 and 0.1 MMAD or between 1 and 3.5 &mgr;m. A gas-flow control valve disposed upstream of the unit functions to limit gas-flow rate through the condensation region to the selected gas-flow rate. An actuation switch in the device activates the drug-supply unit, such that the drug-supply unit can be controlled to produce vapor when the gas-flow rate through the chamber is at the selected flow rate.
