1. A therapeutic agent delivery system, comprising:
a housing;
a drive wheel carried by the housing, the drive wheel being rotatable relative to the housing;
a plunger rod being rotatable with the drive wheel relative to the housing from a first rotational configuration to a second rotational configuration, and the plunger rod being translatable relative to the housing from a first translational configuration to a second translational configuration;
a plunger restraint maintaining the plunger rod in the first translational configuration when the plunger rod is disposed in the first rotational configuration, and the plunger restraint permitting the plunger rod to translate to the second translational configuration when the plunger rod is disposed in the second rotational configuration;
a needle being movable relative to the housing from a stowed configuration to a deployed configuration, and the needle being moved from the stowed configuration to the deployed configuration by the plunger rod when the plunger rod moves from the first translational configuration to the second translational configuration; and
a therapeutic agent delivery assembly carrying a therapeutic agent and in communication with the needle, and the therapeutic agent delivery assembly being actuated by rotation of the drive wheel relative to the housing and thereby delivering the therapeutic agent to the needle.
