  • Publication number: 20250000698
    Abstract: 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.

  • Publication number: 20240082058
    Abstract: 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.

  • Patent number: 11358719
    Abstract: An aerial vehicle including a first wing structure and a second wing structure which intersects the first wing structure perpendicularly at a position offset from a midpoint of a transverse axis of the first wing structure in a direction towards a first wingtip of the first wing structure. The aerial vehicle may further include a first set of at least two propellers with respective propeller rotational axes disposed side-by-side along a portion of the first wing structure extending between the midpoint of the transverse axis of the first wing structure and a second wingtip of the first wing structure. The aerial vehicle may further include a second set of at least two propellers with respective propeller rotational axes disposed side-by-side along a first portion of the second wing structure extending from a first surface of the first wing structure.

A sleeve may be used to guard the blade tip while leaving a sharp cutting tip exposed.

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.

  • Patent number: 11212244
    Abstract: 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.

  • Patent number: 11146513
    Abstract: 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.
