Publication number: 20250000698Abstract: A macular indentor for implantation on an eye of a patient includes a curved backbone extending from a first end to a second end and a raised pad coupled to the first end of the backbone. The raised pad extends inward from an inner face of the backbone such that, when the macular indentor is implanted on the eye, the raised pad applies pressure to the sclera of the eye which contacts the macula of the eye. The geometry of the backbone is configured to match the geometry of the eye.Type: ApplicationFiled: July 10, 2024Publication date: January 2, 2025Inventor: Ian CHAN

Publication number: 20240082058Abstract: This disclosure relates to a surgical instrument assembly useful during retinal surgery. In particular, a surgical instrument described herein may be constructed from a small gauge. A guarded blade having a reversibly exposed sharp blade tip is described. A sleeve may be used to guard the blade tip while leaving a sharp cutting tip exposed. Use of a sleeve to guard the blade while allowing the sharp tip to remain exposed may allow for safer dissection of tissues. When used for surgeries involving the eye, a blade having a polymer sleeve and a reversibly exposed tip may inhibit and/or avoid the occurrence of inadvertent retinal tissue injury. The tip can be covered with a movable cylindrical shield to protect the tip during inserting into the eye then retracted to expose the tip during the cutting procedure.Type: ApplicationFiled: November 3, 2023Publication date: March 14, 2024Inventor: Ian CHAN

In particular, a surgical instrument described herein may be constructed from a small gauge. A guarded blade having an exposed sharp blade tip is described. A sleeve may be used to guard the blade tip while leaving a sharp cutting tip exposed. Use of a sleeve to guard the blade while allowing the sharp tip to remain exposed in the manner of the invention may allow for safer dissection of tissues. When used for surgeries involving the eye, a blade having a polymer sleeve and an exposed tip may inhibit and/or avoid the occurrence of inadvertent retinal tissue injury. For example, using a small gauge blade guarded by a polymer sleeve during retinal surgical procedures may reduce or inhibit injuries to the retinal tissue when used during retinal surgical procedures such as membrane peeling and/or dissection.Type: ApplicationFiled: July 26, 2021Publication date: January 27, 2022Inventor: Ian CHAN

Patent number: 11212244Abstract: A method for using an in-message application. The method includes: receiving a broadcast message; identifying, in the broadcast message, a reference to an external data provider; obtaining an identifier of the in-message application from the external data provider; using the identifier to identify a set of components of the in-message application, where placement of the set of components is defined by a visual structure of the in-message application, and where each of the set of components is a user interface (UI) element; associating data obtained from the external data provider with a component of the set of components; and serving the broadcast message and the data to a consumer client, where the consumer client renders the in-message application based on the visual structure.Type: GrantFiled: September 17, 2019Date of Patent: December 28, 2021Assignee: Twitter, Inc.Inventors: William Morgan, Jeremy Gordon, Grant Monroe, Buster Benson, Russell D'Sa, Adam Singer, Ian Chan, Brian Ellin, Reeve Thompson, Lucas Alonso-Martinez

Patent number: 11146513Abstract: Various embodiments disclose an in-message application facilitating the use of third-party application programming interfaces (APIs). In particular, these in-message applications (referred to as “cards”) may be designed by a developer to access third-party API functionality. A user may then create a message referencing, e.g., a web address associated with the developer's card. The system may receive the user's message and recognize the reference. The system may then distribute an instantiation of the card to various recipients, the instantiation including elements generated using, or providing the user access to, the third party functionality.Type: GrantFiled: September 24, 2019Date of Patent: October 12, 2021Assignee: Twitter, Inc.Inventors: Brian Guarraci, William Morgan, Jeremy Gordon, Grant Monroe, Buster Benson, Russell D'sa, Adam Singer, Ian Chan, Brian Ellin, Reeve Thompson, Luke Alonso, Zachary Taylor, Zhigang Chen
