Claims for Patent: 8,608,698

Title:Devices, systems and methods for medicament delivery
Abstract: An apparatus includes a housing, a needle, a first energy storage member and a second energy storage member. The needle is movably disposed within the housing and is configured to be to be placed in fluid communication with a medicament container. The needle is configured to move between a first position and a second position. In its first position, the needle is contained within the housing. In its second position, at least a portion of the needle extends from the housing. The first energy storage member is disposed within the housing, and is configured to produce a first force when actuated. The second energy storage member is disposed within the housing, and is configured to be actuated in response to the first force to produce a second force to move the needle from the first needle position to the second needle position.

Assignee: Intelliject, Inc. (Richmond, VA)
Application Number:13/053,451
Patent Claims: 1. An apparatus, comprising: a housing; a needle movably disposed within the housing, the needle configured to be placed in fluid communication with a medicament container, the needle configured to be moved in a first direction from a first needle position to a second needle position, the needle disposed within the housing when the needle is in the first needle position, a portion of the needle disposed outside of the housing when the needle is in the second needle position; a first energy storage member disposed within the housing, the first energy storage member configured to produce a first force when the first energy storage member is actuated; a second energy storage member disposed within the housing, the second energy storage member configured to be actuated in response to the first force to produce a second force to move a portion of a plunger within the medicament container when the needle is in the second needle position; a third energy storage member configured to produce a third force to move the needle in a second direction opposite the first direction; a transfer member configured to move within the housing when the first energy storage member is actuated, a portion of the transfer member configured to move the second energy storage member; and a release member configured to release at least the second force from the portion of the plunger, the needle configured to move in the second direction after the second force is released.

2. The apparatus of claim 1, wherein a longitudinal axis of the first energy storage member is coaxial with a longitudinal axis of the second energy storage member.

3. The apparatus of claim 1, wherein: the transfer member is coupled to the first energy storage member, the transfer member configured to transfer at least a portion of the first force to the second energy storage member when the first energy storage member is actuated.

4. The apparatus of claim 1, wherein: the transfer member is configured to move in a first direction within the housing when the first energy storage member is actuated, and the needle is configured to move in a second direction from the first needle position to the second needle position, the second direction different from the first direction.

5. The apparatus of claim 1, further comprising: an actuator coupled to a distal end portion of the housing, the actuator configured to actuate the first energy storage member.

6. The apparatus of claim 1, wherein a longitudinal axis of the needle is non-coaxial with the longitudinal axis of the first energy storage member.

7. The apparatus of claim 1, wherein: the first energy storage member is any one of a spring or a gas container; and the second energy storage member is any one of a spring or a gas container.

8. The apparatus of claim 1, further comprising: the medicament container containing epinephrine.

9. An apparatus, comprising: a housing; a needle movably disposed within the housing, the needle configured to be placed in fluid communication with a medicament container; a first energy storage member disposed within the housing, the first energy storage member configured to produce a first force when the first energy storage member is actuated, the first energy storage member being any one of a spring or a compressed gas container; an actuator coupled to a distal end portion of the housing, the actuator configured to actuate the first energy storage member; and a second energy storage member disposed within the housing, the second energy storage member configured to be actuated in response to the first force to produce a second force to move the needle from a first needle position to a second needle position, the needle disposed within the housing when the needle is in the first needle position, a portion of the needle disposed outside of the distal end portion of the housing when the needle is in the second needle position, the second energy storage member being any one of a spring or a compressed gas container.

10. The apparatus of claim 9, wherein the first energy storage member is in series with the second energy storage member.

11. The apparatus of claim 9, further comprising: a transfer member coupled to the first energy storage member, the actuator configured to engage the transfer member to actuate the first energy storage member.

12. The apparatus of claim 9, further comprising: a transfer member coupled to the first energy storage member, the transfer member configured to transfer at least a portion of the first force to the second energy storage member when the first energy storage member is actuated, the transfer member configured to move in a first direction within the housing when the first energy storage member is actuated, the needle configured to move in a second direction from the first needle position to the second needle position, the second direction different from the first direction.

13. The apparatus of claim 9, wherein a longitudinal axis of the needle is non-coaxial with a longitudinal axis of at least one of the first energy storage member or the second energy storage member.

14. The apparatus of claim 9, further comprising: a third energy storage member configured to produce a third force to move the needle from the second needle position towards the first needle position.

15. An apparatus, comprising: a housing; a needle movably disposed within the housing, the needle configured to be placed in fluid communication with a medicament container; a first energy storage member disposed within the housing, the first energy storage member configured to produce a first force to move the needle within the housing in a first direction when the first energy storage member is actuated; a second energy storage member disposed within the housing, the second energy storage member configured to produce a second force to move the needle within the housing in a second direction opposite the first direction, a longitudinal axis of the second energy storage member being offset from a longitudinal axis of the needle; and a third energy storage member configured to produce a third force to actuate the first energy storage member, the third energy storage member in series with the first energy storage member.

16. The apparatus of claim 15, wherein: the first energy storage member is a gas container configured to produce a pressurized gas; and the second energy storage member is a spring.

17. The apparatus of claim 15, wherein a longitudinal axis of the needle is non-coaxial with a longitudinal axis of at least one of the first energy storage member or the second energy storage member.

18. The apparatus of claim 15, further comprising: an actuator coupled to a distal end portion of the housing, the actuator configured to actuate the first energy storage member.

19. The apparatus of claim 15, further comprising: the medicament container containing epinephrine.

20. The apparatus of claim 1, wherein the first energy storage member is in series with the second energy storage member.

21. The apparatus of claim 1, wherein: the portion of the plunger is a first portion, the release member configured to engage a second portion of the plunger to release at least the second force.

22. The apparatus of claim 1, wherein the transfer member includes a protrusion configured to engage a portion of the housing to limit movement of the transfer member within the housing.

23. The apparatus of claim 9, further comprising: the medicament container containing epinephrine.
