  • Publication number: 20220117472
    Abstract: Ophthalmic endoscopes are provided that overcome deficiencies associated with current approaches to implanting ophthalmic stents and shunts for treatment of glaucoma. In various aspects, ophthalmic endoscopes are provided having an elongated body, an instrument port, a micro fiber-optic camera, and in some aspects an irrigation port, wherein the irrigation port extends at least the length of the elongated body from the proximal end to the distal end. The use of the fiber-optic camera and the angle of the irrigation port can allow the device to be operated with a single hand and to overcome the difficult positioning associated with conventional implantation procedures. Ophthalmic endoscopy systems are also provided including the endoscope and a video processor. Methods of implanting an ophthalmic implant using the ophthalmic endoscopes and endoscopy systems are also provided.

  • Patent number: 9895013
    Abstract: A drinking container includes a base and a sidewall extending upwardly from the base. The base and the sidewall define a cavity. The drinking container includes an ice retaining structure in the cavity, with the ice retaining structure including a ring member held adjacent an inner surface of the sidewall. The ring member and the sidewall define at least one laterally extending gap therebetween. The ice retaining structure is positioned and configured to retain ice in the cavity and to permit liquid to pass through the at least one gap when the drinking container is tilted relative to vertical.

  • Publication number: 20030167471
    Abstract: A system and method for managing series video-on-demand (SVOD) products is described. One implementation of the described device includes the steps of receiving a selection to activate a SVOD guide; retrieving a list of SVOD providers; retrieving display data for each of the SVOD providers included in the list of SVOD providers; and initiating display of the retrieved display data for each of the SVOD providers, wherein a user can select at least one of the SVOD providers.
