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.

Devices and processes for delivery of therapeutic fluids

A therapeutic agent delivery system () includes a housing () and a drive wheel () rotatably carried by the housing. A plunger rod () may be rotatable with the drive wheel relative to the housing from a first rotational configuration to a second rotational configuration. The plunger rod may be translatable relative to the housing from a first translational configuration to a second translational configuration. A plunger restraint () may maintain the plunger rod in the first translational configuration when the plunger rod is disposed in the first rotational configuration. The plunger restraint may permit the plunger rod to translate to the second translational configuration when the plunger rod is disposed in the second rotational configuration. A needle may move from a stowed configuration to a deployed configuration by the plunger rod when the plunger rod moves from the first translational configuration to the second translational configuration.

Systems, devices, and processes for delivery of therapeutic fluids

A chemical reaction system is disclosed for use in a device for delivering a therapeutic fluid comprising a liquid base and a polymeric acid. A reaction rate of the chemical reaction system is capable of being adjusted by adjusting at least one of surface area-to-volume ratio, acid concentration, and cross-linking of the polymeric acid.

System for controlling gas generation within a drug delivery device

Processes and devices provide parenteral delivery of therapeutic fluids, in particular high-viscosity therapeutic fluids (e.g., protein therapeutics), by a chemical reaction that generates a gas. A device may include a first actuation chamber containing a first reagent, a second reaction chamber containing a second reagent, and a third therapeutic fluid chamber containing the therapeutic fluid. In a loaded configuration, a plunger separates the first chamber from the second chamber. In a delivery configuration, the plunger allows the first reagent from the first chamber to communicate and react with the second reagent from the second chamber. The generated gas acts upon a plunger to deliver the therapeutic fluid from the third chamber.
