  • Publication number: 20240156683
    Abstract: Disclosed is a reusable actuator for use with a drug container including a stopper comprising a container having a closed end, an open end, and a sidewall extending therebetween in a longitudinal direction, an electrode disposed inside the container for use in generating a gas, an actuating element disposed at and closing the open end of the container, the actuating element and the container defining an actuator interior, wherein the actuating element is movable relative to the container in the longitudinal direction by a gas pressure of the gas in the actuator interior, such that the actuating element applies a force to the stopper to cause a drug delivery from the drug container, and a retracting mechanism for use in removing the gas to assist the actuating element's retraction for reuse.
