  • Patent number: 10966822
    Abstract: A method for manufacturing a heart valve using bioprosthetic tissue that exhibits reduced in vivo calcification. The method includes applying a calcification mitigant such as a capping agent or an antioxidant to the tissue to specifically inhibit oxidation in tissue. Also, the method can be used to inhibit oxidation in dehydrated tissue. The capping agent suppresses the formation of binding sites in the tissue that are exposed or generated by the oxidation and otherwise would, upon implant, attract calcium, phosphate, immunogenic factors, or other precursors to calcification. In one method, tissue leaflets in assembled bioprosthetic heart valves are pretreated with an aldehyde capping agent prior to dehydration and sterilization.

    Abstract: An objective of the present invention is to provide methods of producing human collagen molecules that are easy to isolate and purify and that have a structure substantially equivalent to that of a natural collagen molecule, wherein host cells that are transduced with a collagen gene synthesize large amounts of human collagen protein derived from a gene introduced into a high exogenous gene expression vector. Another objective of the present invention is to provide collagen molecules produced by the production methods. The present inventors discovered that a large amount of human collagen hardly contaminated with host cell-derived collagen could be produced, by selecting from various mammalian cells a host cell that has low collagen expression and introducing a collagen gene construct into a vector capable of high exogenous gene expression.

  • Patent number: 9006182
    Abstract: A light activated collagen-flavin composite layer incorporating riboflavin is applied as treatment for infected lesions. These composites have also been found to be strong tissue adheives that are effective in closing and sealing wounds, fixation of grafts/ implants and anastomoses. Advantages include speed of closure, reduced infection due to the elimination of foreign matter, evidence of accelerated wound healing and the ease of use in complex surgery, especially when watertight seals, limited access or small repair size are important factors. The riboflavin in the collagen layer is exposed to light (e.g., light having a wavelength between 360-375 nm or 440-480 nm), decomposing the riboflavin to form reactive oxygen species (ROS). Strong crosslinks between the collagen composite and tissue results. In addition, similar exposures eradicate pathogens in the wound.

  • Publication number: 20150065429
    Abstract: Degradable bioprostheses made of collagen-based material having amine-based and ester-based crosslinks are provided, as are methods for their formation and use. Some embodiments of the present invention are directed towards a method of controlling the ratio of amine-based crosslinks to ester-based crosslinks within a collagen-based material to provide a tailorably crosslinked collagen-based material. Some embodiments provide a method of making a degradable bioprosthesis involving controlling crosslinking to afford a degradable bioprosthesis that is partially crosslinked. By controlling the ratio of amine-based to ester-based crosslinks, by controlling the level of crosslinking, or by controlling both of these features, degradable bioprostheses with tailored degradation rates can be synthesized. Some embodiments of degradable bioprostheses have degradation rates that are tailored to allow their use in particular medical applications.

  • Patent number: 8969523
    Abstract: An object is to provide a sebum secretion inhibiting composition and a food or drink product using the same. The present inventors have conducted extensive studies and consequently found that the sebum secretion is inhibited by orally ingesting a collagen peptide, which is hydrolyzed collagen, and provide an oral sebum secretion inhibiting composition comprising a collagen hydrolysate and a food or drink product containing the composition.

  • Patent number: 8969522
    Abstract: An object is to provide a method for producing an ever-larger molecular weight collagen-like polypeptide single strand. Another object is to provide a method for controlling a molecular weight of a product to be obtained in desired magnitude upon producing a collagen-like polypeptide single strand. A solution is a method for producing a polypeptide including a step for allowing a condensation reaction of peptide oligomers represented by any one of formulas (1) to (3) (SEQ ID No:1 to SEQ ID No:3), wherein the condensation reaction is carried out in an aqueous solvent containing a phosphate ion in the range of 0 M to less than 0.01 M in the presence of a condensing agent, or a condensing agent and a condensing auxiliary: H-(Pro-Y-Gly)n-OH??(1); H-(Y-Gly-Pro)n-OH??(2); and H-(Gly-Pro-Y)n-OH??(3); wherein, in formulas (1) to (3), Y is hydroxyproline or proline, and n is an integer from 1 to 10.

  • Patent number: 8951598
    Abstract: Nano scale collagen particles can be obtained from an embrittling and attrition process that reduces the size of collagen particles to the nano scale. These nano scale collagen particles have many favorable properties such as providing beneficial and enhanced properties for cell seeding and wound healing. The nano scale collagen particles can be included in biocompatible (e.g., biostable or biodegradable) compositions and are useful for wound treatment and management, as well as in cell cultures and tissue engineering implants.
