Aseptic piercing system and method

An injection device, comprising:

• a container configured to enclose a fluid, the container having a first end and a second end;
• a conduit movable between a retracted configuration and a deployed configuration;
• an expandable element having a compressed configuration and an expanded configuration, the expandable element being coupled to the conduit, wherein the expandable element is in the compressed configuration when the conduit is in the retracted configuration;
• and
• a lock configured to maintain the expandable element in the compressed configuration while the lock is in a first position, wherein movement of the lock from the first position to a second position allows the expandable element to move from the compressed configuration to the expanded configuration and drive the conduit into fluid communication with the fluid enclosed in the container.

An injection device, comprising:

• a container configured to enclose a fluid, the container having a first end and a second end;
• a conduit movable from a retracted configuration to a deployed configuration;
• a spring having a compressed configuration and an expanded configuration, the spring being coupled to the conduit, wherein the spring is in the compressed configuration when the conduit is in the retracted configuration and movement of the spring from the compressed configuration to the expanded configuration causes the conduit to come into fluid communication with the fluid in the container;
• a collar coupled to the second end of the container, wherein the collar includes a distal axial edge;
• and
• a retainer member slidable relative to the collar, wherein the retainer member includes a radially- or laterally-inwardly extending cam, latch, or actuation portion, wherein the spring is held in the first configuration by the cam, latch, or actuation portion.
