Abstract

An apparatus includes a housing, a medicament container, an actuator, and a biasing member. The actuator is configured to move the medicament container within the housing when the actuator is moved from a first configuration to a second configuration. The actuator includes a gas container and a puncturer. When the actuator is in the first configuration, a portion of the puncturer is disposed apart from the gas container. When the actuator is in the second configuration, the portion of the puncturer is disposed within the gas container. The gas container has a longitudinal axis offset from a longitudinal axis of the medicament container. The biasing member is configured to bias the actuator toward the second configuration.

2. The apparatus of claim 1, wherein the first medicament container is non-coaxial with the second medicament container.

3. The apparatus of claim 1, wherein the first medicament container and the second medicament container are configured to move simultaneously from their respective first container positions to their respective second container positions.

4. The apparatus of claim 1, wherein:

a first protrusion of the movable member is disposed within the first medicament container and coupled to the first elastomeric member therein; and

a second protrusion of the movable member is disposed within the second medicament container and coupled to the second elastomeric member therein.

5. The apparatus of claim 1, wherein:

the energy storage member is a compressed gas container configured to convey a pressurized gas into the housing to produce the force; and

the release mechanism includes a valve configured to release the pressurized gas via an opening when the portion of the movable member is interfaced with the release mechanism.

6. The apparatus of claim 1, wherein:

the energy storage member is a compressed gas container configured to convey a pressurized gas into the housing to produce the force; and

the release mechanism includes a seal member configured to maintain the pressurized gas within the housing, the seal member being movable to release the pressurized gas via an opening when the portion of the movable member is interfaced with the release mechanism.

7. The apparatus of claim 1, further comprising:

a plurality of retraction springs configured to bias the first medicament container and the second medicament container towards their respective first container positions.

8. The apparatus of claim 1, wherein the first medicament container and the second medicament container are configured to move simultaneously from their respective second container positions towards their respective first container positions after the force is released from the first elastomeric member and the second elastomeric member.

9. An apparatus, comprising:

a housing;
