Devices, methods, and kits for ocular drug delivery are described herein. An apparatus can include a housing, an energy storage member, a barrel, and a hub. The housing contains the energy storage member. A proximal end portion of the barrel is coupled to a distal end portion of the housing. The barrel is configured to contain medicament and includes at least a portion of a piston and an elastomeric member. The piston is configured to move the elastomeric member within the barrel in response to a force produced by the energy storage member. The hub is coupled to a distal end portion of the barrel. An inner surface of the hub defines a nozzle through which the medicament flows when the elastomeric member moves within the barrel. The nozzle and the energy storage member are collectively configured to produce a fluid jet to access a target location within an eye.

Systems and methods for ocular drug delivery

Methods and devices are provided for targeted administration of a drug to a patient's eye. In one embodiment, the method includes inserting a hollow microneedle into the sclera of the eye at an insertion site and infusing a fluid drug formulation through the inserted microneedle and into the suprachoroidal space of the eye, wherein the infused fluid drug formulation flows within the suprachoroidal space away from the insertion site during the infusion. The fluid drug formulation may flow circumferentially toward the retinochoroidal tissue, macula, and optic nerve in the posterior segment of the eye.

Methods and devices for drug delivery to ocular tissue using microneedle

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.

Apparatus and methods for drug delivery using multiple reservoirs

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.
