Therapeutic agent delivery devices are provided. Aspects of the devices include an active agent composition and an actuator configured to deliver the active agent composition to a target delivery site. In some instances, aspects of the devices include a syringe comprising a viscous active agent composition, a needle operably coupled to the syringe and an actuator configured to deliver viscous active agent composition from the syringe through the needed to a target delivery site, such as an intravitreal site. In some instances, aspects of the devices include a sleeve comprising a solid formulation of the active agent; a needle operably coupled to the sleeve; and an actuator configured to move the solid formulation from the sleeve and through the needle, e.g., to an intravitreal location. In some instances, aspects of the devices include a syringe containing a composition for subcutaneous delivery, a needle operably coupled to the syringe, a motorized actuator configured to deliver the composition from the syringe through the needle to a target subcutaneous site, and a pain mitigation system. Also provided are methods of using the devices. |
