  • Publication number: 20170095417
    Abstract: Micro implement with micro payload is used for painless and safe percutaneous drug delivery. The micro•head made of maltose or saccharide contains drug and stands on micro-stem installed in orifice of stem holder. Non drug micro-stem supports the payload to adjust insertion depth and reach an interest region under skin and is set to come out from the orifice just after insertion. The payload is completely bullet-like inserted into skin and the drug contained micro•head in the upper micro payload is also delivered into skin completely. The bioavailability 100% is accomplished. The inserted payload solves in internal water and releases drug around the interest region. The implement is composed of payload and holder. The payload is unified of micro•head with drug and non-drug micro•stem. All saccharides means ecologically disposable.

  • Patent number: 8353861
    Abstract: An applicator for applying functional substances, such as cosmetic powder, food color marking, India ink effect marks, or drugs into human skin, having a base, a plurality of microneedles fixed to and projecting from the base a distance only sufficient to penetrate into the stratum corneum or dermis, with the microneedles being of a material that is capable of disintegration and dispersion into the stratum corneum or dermis, such as maltose. The needles contain the functional substance for delivery into the stratum corneum or dermis. The microneedles are of a length approximately 0.5 to 500 ?m when used to apply a functional substance to the stratum corneum, or are of a length of approximately 500 to 5,000 ?m when used to apply a functional substance to the dermis.

  • Patent number: 8167852
    Abstract: Microneedle device is provided, which include microneedles that can be easily inserted into skin and dissolve or swell in skin. The microneedle devices comprise a substrate and cone-shaped or pyramid-shaped microneedles for skin insertion set on the substrate. The microneedles for skin insertion contain over 50 weight percent of one or multiple biomaterials chosen from chitosan, collagen, gelatin, hyaluronic acid, and they are fabricated from the materials that can dissolve or swell in the body.

  • Patent number: 7440004
    Abstract: A viewing system and method for producing at least one image for being perceived as three-dimensional, including at least one of: a provision for compensating the center-of-interest of the at least one image in such a manner as to reduce convergence-accommodation conflict; a provision for configuring the viewing system such that crosstalk produced by a stereo display is perceived as foreground and background blur instead of ghosting; and a provision for viewing the at least one image via automicrostereopsis.
