  • Publication number: 20020137024
    Abstract: The present invention provides methods of inactivating and removing infectious agents from tissues of use in bioprosthetic devices. The methods include the removal and blockage of binding sites on the tissues for the infectious agents. Also provided are methods for blocking a site on an infectious agent that binds to a site on the tissue. The invention also provides a method for preventing or reducing the calcification of a bioprosthetic tissue. The method includes removing or blocking a phospholipid calcium nucleation site from the tissue.

  • Publication number: 20020026236
    Abstract: The invention provides methods for treating injuries to one or more internal structures of a subject by administering a drug delivery vehicle to an external surface of the injured structure. The drug delivery vehicle substantially adheres to the site of administration and provides for the release of a bioactive agent that reduces or prevents further injury to the internal structure by disease processes, such as hyperplasia.

  • Publication number: 20010034552
    Abstract: An IOL implantable in an eye comprising an optic having an optical portion for directing light toward the retina of the eye and a cell barrier portion for inhibiting cell growth from the eye in front of or in back of the optical portion. The cell barrier portion circumscribes the optical portion, is incapable of focusing light on the retina and includes an irregularly configured structure, for example, irregular grooves. At least one elongated fixation member is coupled to the optic for use in fixing the optic in the eye.

  • Publication number: 20010032024
    Abstract: A method for fixation of biological tissues, and bioprosthetic devices prepared by such method. The method generally comprises the steps of A) fixing the tissue, B) treating the tissue with a mixture of i) a denaturant, ii) a surfactant and iii) a crosslinking agent, C) fabricating or forming the bioprosthesis (e.g., forming the tissue and attaching any non-biological components thereto) and D) subjecting the bioprosthesis to terminal sterilization.

  • Patent number: 5803925
    Abstract: Apparatus for inserting intraocular lenses (IOLs) into eyes are disclosed. In one embodiment, such apparatus includes a hollow tube including an interior wall defining a hollow space through which an IOL is passed and an outlet through which the IOL is passed from the hollow space into an eye, and a lubricity enhancing component covalently bonded to the hollow tube at the interior wall in an amount effective to at least assist in facilitating the passage of the IOL through the hollow space.

  • Patent number: 5632773
    Abstract: Corneal implants and methods for producing such implants are disclosed. The present corneal implants comprise a lens body which is optically clear and is structured to be surgically attached in or on the cornea of a mammalian eye, the lens body including a hydrogel composition containing water, a collagen component and a polymeric material covalently bonded to the collagen component. The hydrogel composition has enhanced biostability relative to an identical hydrogel composition without the polymeric material.
