  • Publication number: 20130245600
    Abstract: Drug formulations, devices and methods are provided to deliver biologically active substances to the eye. The formulations are delivered into scleral tissues adjacent to or into the suprachoroidal space without damage to the underlying choroid. One class of formulations is provided wherein the formulation is localized in the suprachoroidal space near the region into which it is administered. Another class of formulations is provided wherein the formulation can migrate to another region of the suprachoroidal space, thus allowing an injection in the anterior region of the eye in order to treat the posterior region.

  • Publication number: 20130144128
    Abstract: A comfortable insert comprises a retention structure sized for placement under the eyelids and along at least a portion of conjunctival sac of the upper and lower lids of the eye. The retention structure resists deflection when placed in the conjunctival sac of the eye and to guide the insert along the sac when the eye moves. The retention structure can be configured in many ways to provide the resistance to deflection and may comprise a hoop strength so as to urge the retention structure outward and inhibit movement of the retention structure toward the cornea. The insert may move rotationally with deflection along the conjunctival sac, and may comprise a retention structure having a cross sectional dimension sized to fit within folds of the conjunctiva. The insert may comprise a release mechanism and therapeutic agent to release therapeutic amounts of the therapeutic agent for an extended time.

  • Publication number: 20130125433
    Abstract: A tailgate cover includes at least one pocket to securely fit over a tailgate. In some embodiments, the tailgate cover includes two or three pockets. The tailgate cover is made of stretchable material such as a stretchable fabric which enables the cover to be stretched securely over the tailgate. To further secure the tailgate cover over the tailgate, any coupling device is able to be used. The tailgate cover is able to include any graphic and/or text.

  • Publication number: 20120136322
    Abstract: A therapeutic system comprises an ocular insert placed on a region outside an optical zone of an eye. The ocular insert comprises two structures: a first skeletal structure and a second cushioning structure. The first structure functions as a skeletal frame which maintains positioning of the implant along the anterior portion of the eye and provides support to the second, cushioning structure. This first structure maintains the attachment of the therapeutic system to the anterior portion of the eye for at least thirty days. In some embodiments the first structure remains a constant size and shape, e.g. a ring shape, a ring with haptics, or a curvilinear ring that is confined to and restrainingly engages the inferior and superior conjunctival fornices so as to retain the implant within the tear fluid and/or against the tissues of the eye.

  • Publication number: 20110208300
    Abstract: A corneal only is configured to adhere to the cornea so as to inhibit epithelial growth under the onlay. Structures can be provided on the onlay to adhere the onlay to the eye. At least one of an epithelial layer or the water inhibiting layer can be provided on or over the onlay, for example a natural epithelial layer or water inhibiting layer that inhibits, for example minimizes, water penetration into the onlay, so as to adhere the onlay to the eye with pumping of the endothelium. The water inhibiting layer may comprise a therapeutic covering positioned over the onlay to inhibit swelling of the cornea. The posterior surface of the onlay may be shaped so as to fit the anterior exposed surface of the cornea.

  • Publication number: 20100036488
    Abstract: A therapeutic lens for the treatment of an epithelial defect comprises a layer of therapeutic material disposed over the stroma and/or Bowman's membrane to inhibit water flow from the tear liquid to the stroma and/or Bowman's membrane, such that corneal deturgescence can be restored to decrease corneal swelling and light scattering. The layer may cover and protect nerve fibers to decrease pain. The layer may comprise an index of refraction to inhibit light scatter from an anterior surface of the stroma and/or Bowman's membrane. The lens may comprise a curved anterior surface that provides functional vision for the patient when the epithelium regenerates. The layer of therapeutic material can be positioned on the eye in many ways, for example with a spray that is cured to adhere the layer to the exposed surface of the stroma and/or Bowman's membrane.

  • Publication number: 20030211137
    Abstract: This invention relates generally to a foamed-wound dressing containing albumin and at least one other protein. The foam dressing is prepared initially as a liquid composition, but forms a foam when a shear force is applied to the liquid. The wound dressing can be prepared as a foam in situ on the surface of the wound or can be pre-formed as a foam and then later applied to a wound. A biocompatible foam wound dressing for human can be prepared using human proteins.
