Fluid path assemblies for drug delivery devices and methods of establishing a fluid flow path for drug delivery devices are described that include a needle shield valve member that couples to a reservoir having a needle mounted thereto. The needle shield valve member includes an internal barrier that protects the needle and/or contains a drug within the reservoir until activation of the drug delivery device. Upon activation, there is relative movement between the reservoir and needle shield valve member until the needle pierces the barrier to establish a fluid flow path from the reservoir through the needle shield valve member.

Fluid path assembly for a drug delivery device

A flexible plunger rod, drug delivery mechanism, drug delivery device, and methods are described that utilize the flexible plunger rod perform drug delivery operations. In embodiments, the flexible plunger rod can be stored in a curved configuration to thereby reduce a footprint of the drug delivery mechanism and device.
