Patents by Inventor Alexei V. Osipov

Alexei V. Osipov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5910537
    Abstract: The present invention is ultraviolet light absorbing biocompatible polymer containing the copolymerization product of a mixture of hydrophobic and hydrophilic acrylic and/or allelic monomers, graft-polymerized with telo-collagen, where the hydrophobic monomers includes at least one ultraviolet light absorbing hydrophobic acrylic or allelic monomer. The present material is useful in the production of deformable lenses, for example, intraocular lenses, refractive intraocular contact lenses, and standard contact lenses useful, for example, for correcting aphekia, myopia and hypermetropia.
    Type: Grant

  • Patent number: 5286829
    Abstract: A biocompatible material which is the product of graft-copolymerization of a water-soluble vinyl and/or an acrylate monomer with a sorption complex of polysilicic acid and collagen that has been rid of pigments, glycoproteins and proteoglycans, or a product obtained by virtue of chemical destruction, with the aid of hydrofluoric acid, of the afore-mentioned product of graft-copolymerization, containing up to 25 mass percent of polysilicic acid (in terms of SiO.sub.2), up to 12 mass percent of protein, and maximum 1 10.sup.-6 mole/g of an anion of hydrofluoric and hydrofluoric acids, methods of making the same and products produced thereby.

  • Patent number: 4978352
    Abstract: A process for producing a collagen-based cross-linked biopolymer is provided in which a collagen solution free of low-molecular impurities is saturated with nitrogen protoxide, its concentration is brought to maximum 80 mass percent and the solution is exposed to an ionizing radiation in a dose of 0.5 to 15 kGy. An implant for hermetization of corneal and scleral wounds involved in eye injuries prepared from said bipolymer has the shape and size that provide for complete hermetization of said wounds. The method for its preparation comprises saturation of a collagen solution free of impurities and having a concentration of 0.2 to 1.3 mass percent, with nitrous oxide, filling of a mould with said solution and its exposure to an ionizing radiation in a dose of 0.5 to 15 kGy. The resultant blank is dried to a moisture content in its biopolymer of 30 to 50 mass percent, whereupon the blank is given the shape and size of a required implant.
