Drug delivery device, method of manufacture, and method of use

A wearable drug delivery device comprising:

• a housing;
• a container disposed at least partially within the housing;
• a first seal at least partially covering an opening formed in a wall of the container;
• a plunger seal moveably disposed within the container;
• a drug disposed within the container, the drug comprising at least one of a granulocyte colony-stimulating factor (G-CSF) or a Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) specific antibody;
• a drive mechanism configured to move the plunger seal through the container to expel the drug from the container;
• a needle having at least:
• a first position wherein a point of the needle is not disposed through a surface of the first seal, and a second position wherein the point of the needle is disposed through the surface of the first seal into the container;
• an insertion mechanism disposed at least partially within the housing, wherein the insertion mechanism comprises:
• a rotational biasing member configured to rotate the insertion mechanism housing,
• a delivery member connected or configured to be connected in fluid communication with the container, the delivery member being moveable between a first position wherein an insertion portion of the delivery member is positioned within the housing and a second position wherein the insertion portion of the delivery member is positioned exterior to the housing for insertion into a patient,
• a hub operably coupled with the delivery member, and
• wherein the insertion mechanism housing is operably coupled with the hub such that initial rotation of the insertion mechanism housing causes the delivery member to move axially from the first position to the second position;
• an ultraviolet (UV) light source;
• and
• wherein at least a portion of the wearable drug delivery device is configured to facilitate UV sterilization of at least a portion of the surface of the first seal.
