  • Publication number: 20200345750
    Abstract: Biocompatible microparticles include an ophthalmically active cyclic lipid component and a biodegradable polymer that is effective, when placed into the subconjunctival space, in facilitating release of the cyclic lipid component into the anterior and posterior segments of an eye for an extended period of time. The cyclic lipid component can be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. Or, the cyclic lipid component can be encapsulated by the polymeric component. The present microparticles include oil-in-water emulsified microparticles. The subconjunctivally administered microparticles can be used to treat or to reduce at least one symptom of an ocular condition, such as glaucoma or age related macular degeneration.

  • Patent number: 10474696
    Abstract: A distributed computer system and method for synchronizing content libraries in replication groups uses a synchronization control signal that is transmitted to a subscribed content library management module of each subscribed content library in a replication group from a content library management module of the master content library in the replication group to initiate a synchronization procedure. Using metadata of at least one consumable software item from the master content library, contents of a subscribed content library in the replication group are modified to synchronize its contents to the contents of the master content library.

  • Patent number: 9782248
    Abstract: One aspect of the present invention is a method of producing a decellularized composite tissue bioscaffold for musculoskeletal tissue interface reconstruction by physicochemically treating a musculoskeletal tissue interface isolated from allogeneic sources. In certain embodiments, such musculoskeletal tissue interfaces can also be isolated from xenogeneic sources. The method comprises treatment of the interface with detergents, chemical oxidants and ultrasonic energy, and wash steps in between to remove residual detergents as well as oxidants. The resulting bioscaffold may be freeze-dried or lyophilized, sterilized and aseptically packaged for subsequent use.

  • Patent number: 9568748
    Abstract: The disclosed technology describes methods for the selection, design and production of custom-fit eyeglasses, using a 3D printer. Embodiments include an eye examination and biometric measurements of a patient. The data can be used to produce custom-fit eyeglass frames. Eyeglass selection is facilitated by the display of a selection of various frames in both digital and physical form. A 3D version of the patient's head may be created from digital images, which can be used to produce a final version of the eyeglass frame. Lens dimensions may be traced and the trace used to modify the eyeglass frame. Half of an eyeglass frame may be generated, from which a mirror image is created, and a final frame produced from the resulting image. Also disclosed is an electronic device system which receives, processes and transmits data for the production of custom-fit eyeglass frames.
