  • Publication number: 20050161041
    Abstract: A method for forming at least one opening in a receptacle comprises the steps of providing a receptacle having a cover with an exterior surface and an interior surface covering a cavity. A cutting mechanism is also provided having at least one blade. The cover is pierced with the blade, and the blade is moved through the cover to cut a portion of the cover and create an opening in the cover to provide access into the cavity. Further, the cut portion curls on top of the exterior surface as the opening is created.

  • Patent number: 6901929
    Abstract: The invention provides various apparatus and methods for aerosolizing a powdered medicament. In one exemplary embodiment, an apparatus includes a pressurization cylinder, and a piston which is slidable within the cylinder to pressurize a gas. A handle is coupled to the piston and is movable between an extended position and a home position to pressurize the gas. An aerosolizing mechanism is included and is configured to aerosolize a powdered medicament that is held within a receptacle with pressurized gas from the cylinder. A carriage assembly is included to receive the receptacle and to couple the receptacle to the aerosolizing mechanism. A first and a second interlock are operably engageable with the carriage assembly to prevent coupling of the receptacle with the aerosolization mechanism. The first interlock is released to allow movement of the carriage upon movement of the handle to the extended position.

  • Publication number: 20050056275
    Abstract: A method for aerosolizing a powder utilizes a receptacle having a cavity containing a powder. An access end of an extraction tube is inserted into the cavity, and an inlet opening is formed in the receptacle. A pressurized gas is flowed through the inlet opening, through the cavity and through the extraction tube to move the powder in the cavity into the extraction tube where the powder is entrained in the gas to form an aerosol.

  • Publication number: 20050056276
    Abstract: An aerosolization device comprises a housing, a container comprising a reservoir storing a pharmaceutical formulation which comprises a propellant, and a metering valve. The metering valve is in communication with the reservoir and is moveable into the container to an actuated position where a predetermined amount of the pharmaceutical formulation is released. A contact member is provided in the housing. In one version, the contact member is moveable between a first position and a second position to allow for selective actuation of the metering valve. In another version, the contact member's configuration may be changed to allow for selective actuation of the metering valve.

  • Publication number: 20050051162
    Abstract: An aerosolization apparatus comprises a container containing a pharmaceutical formulation, the pharmaceutical formulation comprising an active agent and a propellant. The aerosolization apparatus further comprises a metering chamber in communication with the container, the metering chamber adapted to hold a metered amount of the pharmaceutical formulation, a valve to allow the metered amount of the pharmaceutical formulation to be released from the metering chamber when the valve is actuated, and a pressurizer that applies pressure to the pharmaceutical formulation in the metering chamber while the pharmaceutical formulation is being released from the metering chamber. In one version, the metering chamber is sized so that at least 2 mg, and preferably at least 5 mg, of the active agent is be aerosolized for delivery to a user during inhalation.

  • Publication number: 20050016533
    Abstract: Systems and methods are provided for aerosolizing a pharmaceutical formulation. According to one method, respiratory gases are prevented from flowing to the lungs when attempting to inhale. Then, respiratory gases are abruptly permitted to flow to the lungs. The flow of respiratory gases may then be used to extract a pharmaceutical formulation from a receptacle and to place the pharmaceutical formulation within the flow of respiratory gases to form an aerosol.

  • Publication number: 20030168057
    Abstract: An aerosolization device comprises a housing having an inlet and an outlet and an airway extending from the inlet to the outlet. A valve in the airway comprises a piezoelectric element which controls the valve, and a reservoir in communication with the airway is adapted to contain a pharmaceutical formulation so that the pharmaceutical formulation may be introduced into the airway and passed through the outlet in an aerosolized form. The piezoelectric element may alternatively or additionally be used to sense a condition in the aerosolization device.
