Systems and methods for ocular drug delivery

Abstract

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.
