  • Patent number: 12201558
    Abstract: An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.

  • Patent number: 12127975
    Abstract: An apparatus includes a housing, an adjustment member, and a microneedle. The housing can be coupled to a medicament container, and includes a hub surface that can contact a target surface. The adjustment member is within the housing and separates an inner volume of the housing into a first chamber and a second chamber. The first chamber is fluidically coupled with the medicament container. The adjustment member, which is coupled to the microneedle, can transition between a first configuration and a second configuration. A proximal end portion of the microneedle is fluidically coupled to the first chamber such that a substance can be conveyed from the medicament container through the microneedle. A distal tip of the microneedle extends from the hub surface by a first distance when the adjustment member is in the first configuration, and by a second distance when the adjustment member is in the second configuration.

  • Patent number: 12090088
    Abstract: The present invention provides devices to access the suprachoroidal space or sub-retinal space in an eye via a minimally invasive transconjunctival approach. The devices may also be used after a partial dissection, for example after dissection of the outer scleral layer of the eye, and using the device within the dissection to access the suprachoroidal space or the sub-retinal space.

  • Patent number: 11944703
    Abstract: 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.

  • Publication number: 20230363941
    Abstract: Embodiments described herein relate to systems and methods of retinal injection. In some aspects, a method includes inserting a distal end portion of a hollow conduit of a medical injector into an eye of a patient until the distal end portion reaches a reference location, the medical injector having a housing from which the hollow conduit distally extends and confirming disposal of the distal end portion of the hollow conduit in the reference location. After the confirming, the method further includes extending the distal end portion of the hollow conduit distally relative to the housing and from the reference location such that the distal end portion enters an injection region of the eye. With the distal end portion of the hollow conduit disposed in the injection region of the eye, medicament is conveyed into the injection region via the hollow conduit.
