Patent number: 11944703Abstract: An ocular medical injector is provided for drug delivery. A method includes inserting a puncture member of the medical injector into the eye until the puncture member reaches the suprachoroidal space (SCS). The puncture member defines a lumen therethrough. With the puncture member disposed within the SCS, a flexible cannula is advanced distally through the lumen of the puncture member, beyond the distal end portion of the puncture member and along the SCS towards a posterior region of the eye. The flexible cannula has an atraumatic distal tip and defines a lumen therethrough. With the distal tip of the flexible cannula disposed within the SCS beyond a distal end portion of the puncture member, a therapeutic substance is administered to the SCS.Type: GrantFiled: August 3, 2023Date of Patent: April 2, 2024Assignee: Clearside Biomedical, Inc.Inventors: Ronald Yamamoto, Stanley R.

Patent number: 11648935Abstract: A driving assistance system includes a sensor set, a data storage device and an output device. The sensor set detects a set of road users and, for each road user, a current state including a current speed and a current position. The data storage device includes a finite plurality of behavioral models. The data processor assigns a behavioral model to each road user, probabilistically estimates, for each road user, a belief state comprising a set of alternative subsequent states and corresponding probabilities, each alternative subsequent state including a speed and a position, according to the behavioral model assigned to each road user, and determines a risk of collision of the road vehicle with a road user, based on the probabilistically estimated future state of each road user. The output device outputs a driver warning signal or executes an avoidance action if the risk of collision exceeds a predetermined threshold.Type: GrantFiled: October 31, 2016Date of Patent: May 16, 2023Assignee: TOYOTA MOTOR EUROPEInventors: David Sierra Gonzalez, Christian Laugier, Jilles Steeve Dibangoye, Alejandro Dizan Vasquez Govea, Nicolas Vignard

Publication number: 20230102547Abstract: 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: ApplicationFiled: May 6, 2022Publication date: March 30, 2023Inventors: Yair Alster, Eugene de Juan, JR., Cary J.

Patent number: 11364899Abstract: A driving assistance system includes a sensor set, a data storage device and an output device. The sensor set observes apparent states of each road user of the plurality of road users at successive time steps, the data processor assigns a behavioral model stored in the data storage device, the data processor calculating a new maneuver distribution that is a probability distribution over a finite plurality of alternative maneuvers and a new state distribution that is a probability distribution of possible states for each alternative maneuver of the finite plurality of alternative maneuvers. The data processor determines a risk of collision of the road vehicle with another road user, based on the new maneuver and state distributions of the target road user, and outputs one or more of a driver warning signal and executes an avoidance action if the risk of collision exceeds a predetermined threshold.Type: GrantFiled: June 2, 2017Date of Patent: June 21, 2022Assignees: TOYOTA MOTOR EUROPE, INSTITUT NATIONAL de RECHERCHE en INFORMATIQUE et en AUTOMATIQUE (INRIA), INSTITUT NATIONAL DES SCIENCES APPLQUEES DE LYONInventors: Nicolas Vignard, David Sierra Gonzalez, Christian Laugier, Jilles Steeve Dibangoye, Victor Romero-Cano

Publication number: 20210212940Abstract: 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: March 30, 2021Publication date: July 15, 2021Applicant: CLEARSIDE BIOMEDICAL, INC.Inventors: Ronald YAMAMOTO, Stanley R.

Patent number: 10835416Abstract: 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: GrantFiled: February 26, 2018Date of Patent: November 17, 2020Assignee: ForSight Vision5, Inc.Inventors: Eugene de Juan, Yair Alster, Cary J.

Patent number: 10583367Abstract: 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: September 11, 2013Date of Patent: March 10, 2020Inventor: David Sierra

Patent number: 10555804Abstract: 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: March 9, 2018Date of Patent: February 11, 2020Assignee: JOURNEY1, INC.Inventors: Eugene De Juan, Jr., Cary J.
