Devices, systems and methods for medicament delivery
First Claim
1. An apparatus, comprising:
- a housing;
a medicament container disposed within the housing;
an actuator coupled to an end portion of the housing, the actuator configured to move between a first actuator position and a second actuator position;
a plunger having a first plunger end portion and a second plunger end portion, the first plunger end portion configured to move in response to the movement of the actuator to move the second plunger end portion within the medicament container from a first plunger position to a second plunger position;
a medicament container interface disposed within the housing, the medicament container interface coupled to the medicament container and having a portion extending distally beyond a proximal end of the medicament container, the medicament container interface including an end stop surface configured to limit movement of the plunger in a distal direction, the end stop surface between the first plunger end portion and the second plunger end portion; and
a stop member disposed within the housing distally from the end stop surface, the stop member configured to interfere with the medicament container interface to limit movement of the medicament container interface within the housing.

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.

15. An apparatus, comprising:
-
a housing having a distal end portion defining an opening, a spring stop being within the housing; a medicament container configured to move within the housing in a distal direction from a first container position to a second container position; a needle in fluid communication with the medicament container, a portion of the needle being disposed through the opening and outside of the distal end portion of the housing; a needle sheath covering the needle, the needle sheath configured to maintain sterility of the needle; an actuator coupled to the housing, the actuator configured to move from a first actuator position to a second actuator position; a plunger having a first plunger end portion and a second plunger end portion, the first plunger end portion configured to move in the distal direction in response to the movement of the actuator to move the second plunger end portion within the medicament container from a first plunger position to a second plunger position; a spring having a distal end portion engaging the spring stop, the spring configured to urge the medicament container in a proximal direction; a medicament container interface coupled to the medicament container, the medicament container interface including an end stop surface configured to limit movement of the plunger in the distal direction; and a stop member disposed within the housing distally from the end stop surface, the stop member configured to directly contact the medicament container interface to limit movement of the medicament container interface within the housing. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. An apparatus, comprising:
-
a housing; a medicament container within the housing, the medicament container containing a dose of a medicament; a needle coupled to the medicament container, a portion of the needle configured to be disposed outside of a distal end portion of the housing; a needle sheath covering the needle, the needle sheath configured to maintain sterility of the needle; an actuator coupled to the housing, the actuator configured to move between a first actuator position and a second actuator position; a plunger having a first plunger end portion and a second plunger end portion, the first plunger end portion configured to move in response to the movement of the actuator to move the second plunger end portion within the medicament container from a first plunger position to a second plunger position to convey the dose of the medicament from the medicament container through the needle; a medicament container interface disposed within the housing, the medicament container interface coupled to the medicament container and having a portion extending distally beyond a proximal end of the medicament container, the medicament container interface including an end stop surface between the first plunger end portion and the second plunger end portion, the end stop surface configured to limit movement of the plunger when the second plunger end portion reaches the second plunger position, thereby limiting an amount of the medicament to be conveyed; and a stop member disposed within the housing distally from the end stop surface, the stop member configured to interfere with the medicament container interface to limit movement of the medicament container interface within the housing. - View Dependent Claims (24, 25, 26, 27, 28)
