  • Patent number: 8251958
    Abstract: A method and device for intradermal delivery of a reconstituted medicament. The device includes a chamber, which is in fluid communication with a microdevice, e.g. microabrader or one or more microneedles. A cartridge containing the medicament may be located within said chamber. At least one burstable membrane retains a medicament within the housing. The method involves the steps of positioning the device at a delivery site on the skin of a patient and intradermally administering the medicament by dispensing a diluent from a diluent source an through inlet port to rupture the membranes, reconstitute the medicament and deliver the reconstituted medicament through the microdevice to the dermal region of the skin.

  • Patent number: 7896836
    Abstract: A valved medicament delivery device including a housing having a chamber including coaxially aligned inlet and outlet, a medicament cartridge located within the chamber having a passage therethrough and membranes sealing the passage having a burst pressure of less than 10 atmospheres, a manually actuatable fluid delivery device having an outlet in fluid communication with the chamber and a manually actuated valve located between the outlet of the fluid delivery device and the chamber inlet for delivery of fluid under pressure to the valve. The medicament delivery device of this invention may be utilized to deliver a controlled unit dose of a medicament on demand by first pressurizing a pressure chamber in the pressure delivery device upstream of the valve, then opening the valve to open the membranes and express the medicament through the chamber outlet.

  • Patent number: 7850663
    Abstract: A method and device for intradermal delivery of a reconstituted powdered medicament. The device includes a chamber, which is in fluid communication with a microdevice, e.g. microabrader or one or more microneedles. A cartridge containing the powdered medicament may be located within said chamber. At least one burstable membrane retains a powdered medicament within the housing. The method involves the steps of positioning the device at a delivery site on the skin of a patient and intradermally administering the medicament by dispensing a diluent from a diluent source an through inlet port to rupture the membranes, reconstitute the powdered medicament and deliver the reconstituted medicament through the microdevice to the dermal region of the skin.

  • Patent number: 7842310
    Abstract: A method of preparing a pharmaceutical composition is described, comprising 1) atomizing a liquid formulation of a therapeutic agent to produce an atomized formulation; 2) freezing said atomized formulation to form solid particles; and 3) drying said solid particles at about atmospheric pressure to produce a powder, wherein said drying is performed in the presence of vibration, internals, mechanical stirring, or a combination thereof. Another method is described, comprising 1) atomizing a liquid formulation of a therapeutic agent to produce an atomized formulation; 2) freezing said atomized formulation to form solid particles; and 3) drying said solid particles to produce a powder; wherein the atomized formulation comprises droplets having an average mean diameter of between about 35? and about 300?, and/or the powder comprises dried particles having an average mean diameter of between about 35? and about 300?. Compositions made by the above methods, and methods of using the compositions, are also described.
