  • Patent number: 9381680
    Abstract: Methods for fabricating and manufacturing solid solution perforators (SSPs) using sharp metal or glass needles and/or subsequent molding and use are described. The methods entail making microneedles by various precision machining techniques and micromold structures from curable materials. Various designs of patch, cartridge and applicator are described. Also described are methods for adjusting the microneedle mechanical strength using formulation and/or post-drying processes.

  • Publication number: 20130287832
    Abstract: Influenza vaccines are administered using solid biodegradable microneedles. The microneedles are fabricated from the influenza vaccine in combination with solid excipient(s) and, after penetrating the skin, they dissolve in situ and release the vaccine to the immune system. The influenza vaccine is (i) a purified influenza virus surface antigen vaccine, rather than a live vaccine or a whole-virus or split inactivated vaccine (ii) an influenza vaccine prepared from viruses grown in cell culture, not eggs, (iii) a monovalent influenza vaccine e.g. for immunizing against a pandemic strain, (iv) a bivalent vaccine, (v) a tetravalent or >4-valent vaccine, (vi) a mercury-free vaccine, or (vii) a gelatin-free vaccine.

  • Patent number: 8062573
    Abstract: Porous microperforators (210A), preferably in an array of multiple perforators are employed for delivery of a drug, where the micro-perforators may dissolve in situ. Suitable micro-perforators may include multiple layers of dissolvable materials to effect sequential drug delivery. In further aspects, contemplated micro-perforators may employ a diagnostic device in which a detector layer or detector is operationally coupled to the micro-perforators.

  • Publication number: 20090035446
    Abstract: A solid drug solution perforator containing drug particles and/or drug-adsorbed or loaded particles with an associated drug reservoir (SSPP system) are provided for delivering therapeutic, prophylactic and/or cosmetic compounds, diagnostics, and for nutrient delivery and drug targeting. For drug delivery, the SSPP system includes an active drug ingredient in particulate form or drug adsorbed on the particle surface in a matrix material that dissolves upon contact with a patient's body. In a preferred method of transdermal drug delivery, an SSPP system containing a drug-adsorbed microparticle penetrates into the epidermis or dermis, and the drug is released from the (dissolving) SSPP system perforator and desorbed from the particles. An additional drug is optionally delivered from a patch reservoir through skin pores created by insertion of the perforator Formulation and fabrication procedures for the SSPP and associated reservoir are also provided.

  • Patent number: 7211062
    Abstract: A solid drug perforator (SSP) system and an associated drug reservoir are provided for delivering theraputic, prophylactic and/or cosmetic compounds, for nutrient delivery and for drug targeting. For drug delivery, the SSP system includes an active drug ingredient and a matrix of perforator material that biodegrades or dissolves quickly upon contact with a patient's body. The SSP system provides a skin barrier perforator and a controller for prompt initiation and cut-off of drug delivery. In a preferred method of transdermal drug delivery, an SSP system containing a selected drug penetrates into an epidermis or dermis, and the drug is promptly released from the (dissolving) SSP system perforator. An additional drug is optionally delivered from a patch reservoir through skin pores created by insertion of the perforator. Formulation and fabrication procedures for the SSP and associated reservoir are also provided. An SSP system can be fabricated with variety of shapes and dimensions.
