Publication number: 20180177634Abstract: 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.Type: ApplicationFiled: February 26, 2018Publication date: June 28, 2018Inventors: Eugene de Juan, JR., Yair Alster, Cary J. Reich, K. Angela Macfarlane, Janelle Chang, Stephen Boyd, David Sierra, Jose D. Alejandro, Douglas Sutton, Alexander J. Gould

Patent number: 10004636Abstract: 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.Type: GrantFiled: August 5, 2016Date of Patent: June 26, 2018Assignee: ForSight Vision5, Inc.Inventors: Yair Alster, Eugene de Juan, Jr., Cary J. Reich, Stephen Boyd, David Sierra, Jose D. Alejandro, K. Angela Macfarlane, Douglas Sutton

Patent number: 9943401Abstract: 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.Type: GrantFiled: April 6, 2009Date of Patent: April 17, 2018Inventors: Eugene de Juan, Jr., Cary J. Reich, Stephen Boyd, Yair Alster, David Sierra, Hanson S. Gifford, Jose D. Alejandro, Richard L. Lindstrom, K. Angela Macfarlane, Douglas Sutton, John Anthony Scholl

Publication number: 20170340560Abstract: 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.Type: ApplicationFiled: January 4, 2017Publication date: November 30, 2017Inventors: Ronald YAMAMOTO, Stanley R. CONSTON, David SIERRA

Patent number: 9474611Abstract: The present invention relates to a method for manufacturing an implantable prosthesis, in other words, a biomodel, which can be implanted in a patient, preferably in the cranium of a patient. The method is based on the use of commercially available adhesive tape, in order to reduce the manufacturing costs of said implant since there is no need to heat same to very high temperatures in order to mold the material to be implanted. The implant is preferably made of titanium via a cold-production process, which requires initially supplying a rapid prototype from a CAD model that corresponds to a plastic mold, which is covered with commercially available adhesive tape, in order to obtain another model that makes it possible to form the model that will be transferred to titanium, thus reducing the ideal temperature for molding same.Type: GrantFiled: December 14, 2011Date of Patent: October 25, 2016Assignee: INDUSTRIAS MEDICAS SAMPEDRO S.A.Inventors: Mauricio Toro Restrepo, David Sierra Navaro, Balmore Bedoya Henao

Patent number: 9125735Abstract: A corneal onlay 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.Type: GrantFiled: October 4, 2010Date of Patent: September 8, 2015Assignee: Forsight Labs, LLCInventors: Eugene de Juan, Jr., Cary J.

Patent number: 8555416Abstract: Gloves for forming a figure are designed to represent a figure such as an animal with one glove forming a first portion of the figure and a second glove forming a second portion of the figure. For example, for a pair of shark gloves, one glove is the top of the shark's mouth with upper teeth and the second glove is the bottom of the shark's mouth with lower teeth. When worn by a user, the user is able to move the two gloves in an open and closed motion so that the shark appears to be opening and biting down. The gloves provide entertainment as well as motivation for the fans and players.Type: GrantFiled: January 9, 2009Date of Patent: October 15, 2013Inventor: David Sierra
