Claims for Patent: 8,920,377

Title:Devices, systems and methods for medicament delivery
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.
