  • 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.
    Type: Grant

  • 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.

  • Publication number: 20040161489
    Abstract: A molding apparatus and molding method are provided for molding of small objects from a thermoplastic elastomer. The apparatus includes a heated transfer plate assembly, an insulation plate assembly adjacent the transfer plate assembly and a cooled cavity plate assembly. The transfer plate assembly is heated sufficiently to maintain a thermoplastic elastomer in a molten state. The cavity plate assembly is cooled sufficiently to solidify a thermoplastic elastomer injected into cavities of the cavity plate assembly.

  • Publication number: 20030030186
    Abstract: A hydrostatic injection molding apparatus and process are provided for thermoplastic materials, especially thermoplastic elastomers. The apparatus includes a hot pot plate with a transfer chamber for receiving a thermoplastic material. The hot pot plate is heated to maintain the thermoplastic material in the transfer chamber in a molten state. A cavity plate is positioned adjacent the transfer pot plate, the cavity plate is formed with a plurality of cavities extending therein. Gates are formed in the hot pot plate and the cavity plate. The gates in the respective plates register with one another to provide communication between the transfer chamber and the cavities. The cavity plate is cooled to enable a rapid curing of the thermoplastic material therein.
