Abstract: A drive mechanism (100) for use with a drug container (50) in a drug pump, the drug container (50) having a barrel (58) and a plunger seal (60), including a tether, an electrical actuator (101) and a gear interface. Rotation of the gear interface is controlled by the actuator (101). A gear assembly rotationally engages with the gear interface. The gear assembly includes a main gear and a regulating mechanism. Release of the tether is metered by the gear assembly through the regulating mechanism. A piston (110, 1110, 2110) is connected to the tether and is disposed in the barrel (58) and configured to translate axially within the container. A biasing member is disposed at least partially within the barrel (58) and is retained in an energized state between the piston (110, 1110, 2110) and drive housing, wherein the release of the tether controls the free expansion of the biasing member from its energized state and the axial translation of the piston (110, 1110, 2110).

Abstract: Disclosed herein is a wearable drug delivery device including a container filled at least partially with a drug including at least one of a PCSK9 (Proprotein Convertase Subtilisin/Kexin Type 9) specific antibody, a granulocyte colony-stimulating factor (G-CSF), a sclerostin antibody, or a calcitonin gene-related peptide (CGRP) antibody. The wearable drug delivery device may include a needle and an insertion mechanism configured to insert the needle into a patient. A fluid pathway connector may define a sterile fluid flowpath between the container and the insertion mechanism. Optionally, a cannula initially disposed about the needle may be included. The cannula may be retained in the patient at an injection site created by the needle after the needle is withdrawn from the patient. Methods of assembly and operation are also provided.
