Abstract
A therapeutic agent delivery system comprises a housing. A therapeutic agent delivery assembly is carried by the housing. The therapeutic agent delivery assembly comprises a chamber having a passageway. A therapeutic agent is carried in the passageway, and a needle is in communication with the passageway. The therapeutic agent delivery assembly may be translatable relative to the housing from a stowed configuration to a deployed configuration. Actuation of a user input may translate the therapeutic agent delivery assembly from the stowed configuration to the deployed configuration. An input restraint may be rotatable relative to the housing from a first rotational configuration to a second rotational configuration. In the first rotational configuration the input restraint may inhibit actuation of the user input, and in the second rotational configuration the input restraint may permit actuation of the user input.
