    Abstract: Drug delivery systems with reduced hold-up volumes are provided. The drug delivery systems include a cartridge configured to hold a liquid drug. A cartridge stopper is positioned in a first portion of the cartridge. A needle guide component is positioned within the cartridge stopper. A needle is positioned within a central opening of the needle guide. A plunger is positioned in a second portion of the cartridge. The plunger includes a fluid path pocket facing and aligned with the central opening of the needle guide component. The plunger is driven toward the cartridge stopper to expel the liquid drug from the cartridge through the needle. An end of the needle can be positioned within the fluid path pocket when the plunger is pushed against the cartridge stopper, ensuring that only a small volume of the liquid drug remains in the cartridge when delivery of the liquid drug is completed.

    Abstract: A wearable drug delivery device that can deliver a liquid drug stored in a container to a patient or user is provided. A soft needle or cannula can be placed in fluid communication with the liquid drug and can be coupled to a needle insertion component that provides access to the patient. A drive system of the drug delivery device can expel the liquid drug from the container to the patient through the soft needle or cannula. The wearable drug delivery device can include components for preventing backflow and eliminating air within the liquid drug. As a result, the comfort of the patient can be enhanced and correct drug dosages can be provided when using the drug delivery device.

    Abstract: Systems and methods for automatically delivering medication to a user. A sensor coupled to a user can collect information regarding the user. A controller can use the collected information to determine an amount of medication to provide the user. The controller can instruct a drug delivery device to dispense the medication to the user. The drug delivery device can be a wearable insulin pump that is directly coupled to the user. The controller can be part of or implemented in a cellphone. A user can be required to provide a confirmation input to allow a determined amount of insulin to be provided to the user based on detected glucose levels of the user. The sensor, controller, and drug delivery device can communicate wirelessly.
