Abstract: An apparatus includes a first tray member, a second tray member, and a lid. The first tray member has a first portion and a second portion. The first portion defines a first volume, and the second portion defines a second volume configured to receive a medicament container. The second tray member defines a third volume having a sidewall including a retention portion configured to retain an ocular injector within the third volume. The second tray member is coupled within first volume such that the sidewall of the second tray member and a sidewall of the first tray member enclose the ocular injector. The lid is coupled to the first tray member about the first volume, and is constructed from a material formulated to maintain sterility of the first volume.

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.

Abstract: A cartridge, including a first member that defines an inner volume and a second member disposed therein, is disposed in a housing. A first reservoir is disposed in the inner volume in a position distal to the second member. The first member is partially disposed in a second reservoir, defined by the housing. The second member is configured to be moved from a first position, in which the first reservoir contains a drug and the second reservoir is fluidically isolated from the inner volume, toward a second position, in which the first reservoir and the second reservoir are in fluid communication with the inner volume, such that the second reservoir receives a volume of the drug from the first reservoir. The first member and the second member are collectively moved relative to the second reservoir to expel the volume of the drug from the second reservoir.

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.

Abstract: An apparatus includes a microneedle that defines a lumen therethrough. The microneedle has a proximal end portion a distal end portion and a hub portion between the proximal end portion and the distal end portion. The proximal end portion is configured to be coupled to a medicament container, such as, for example a syringe. The portion of the lumen within the proximal end portion has a first diameter. The distal end portion is configured to pierce a target tissue. The portion of the lumen within the distal end portion has a second diameter smaller than the first diameter. The hub portion includes a surface configured to contact the target tissue when the distal end portion is disposed with the target tissue.

Abstract: Methods and devices are provided for targeted non-surgical administration of a drug formulation to the suprachoroidal space (SCS) of the eye of a human subject for the treatment of a posterior ocular disorder or a choroidal malady. In one embodiment, the method comprises inserting a hollow microneedle into the eye at an insertion site and infusing a drug formulation through the inserted microneedle and into the suprachoroidal space of the eye, wherein the infused drug formulation flows within the suprachoroidal space away from the insertion site during the infusion. In one embodiment, the fluid drug formulation comprises drug nanoparticles or microparticles.

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.
