Abstract

Claims (37)

1. An agent administration device comprising:

a housing;

a sharp assembly including a delivery sharp, the sharp assembly reciprocally displaceable along a guide channel of the housing;

an access port in fluid communication with the delivery sharp; and

an actuation assembly configured to drive the sharp assembly, via urging of a single bias member, from a storage state in which the delivery sharp is within the housing, through a first extended position in which the delivery sharp extends a maximum distance from the housing and to a partially retracted position in which the delivery sharp is stationary and extends a lesser distance from the housing.

2. The agent administration device of claim 1 , wherein the guide channel defines an insertion angle of the delivery sharp.

3. The agent administration device of claim 1 , wherein the access port includes a pierceable septum.

4. The agent administration device of claim 1 , wherein the single bias member is a torsion spring.

5. The agent administration device of claim 1 , wherein the maximum distance is sufficient to penetrate transcutaneously into a patient.

6. The agent administration device of claim 1 , wherein the lesser distance corresponds to a penetration depth in a patient suitable for intradermal administration of agent.

7. The agent administration device of claim 1 , wherein the agent administration device is configured to deliver an agent which includes at least one vaccine.

8. The agent administration device of claim 1 , wherein the device further comprises a removable lock member configured to hold the sharp assembly in the storage state when installed in the device.

9. The agent administration device of claim 1 , wherein the agent administration device further comprises a stowing assembly, and wherein when the sharp assembly is in the partially retracted position, the sharp assembly is configured to displace, via urging of the single bias member, from the partially retracted position to a further retracted position in which the delivery sharp is within the housing upon transition of the stowing assembly from a first state to a second state.

10. The agent administration device of claim 2 , wherein the insertion angle is 5°-45°.

11. An agent administration device comprising:

a housing including a guide;

a sharp assembly including at least one delivery sharp, the sharp assembly reciprocally displaceable along the guide;

an access port in fluid communication with the delivery sharp; and

an actuation assembly coupled to the sharp assembly and including a guide pin, the sharp assembly being displaced from a storage state to an administration state in which the at least one delivery sharp extends a target distance out of the housing as the guide pin displaces from a starting position to a stop in a single direction, the at least one delivery sharp extending a distance greater than the target distance as the guide pin is displaced along an intermediate portion of a displacement range of the guide pin between the starting position and the stop.

12. The agent administration device of claim 11 , wherein the single direction is selected from a group consisting of a clockwise direction and a counterclockwise direction.

13. The agent administration device of claim 11 , wherein the guide defines an insertion angle of the delivery sharp.

14. The agent administration device of claim 11 , wherein the access port includes a pierceable septum.

15. The agent administration device of claim 11 , wherein the distance greater than the target distance is a distance sufficient to penetrate transcutaneously into a patient.

16. The agent administration device of claim 11 , wherein the target distance corresponds to a penetration depth in a patient suitable for intradermal administration of an agent.

17. The agent administration device of claim 11 , wherein the agent administration device is configured to deliver an agent which includes at least one vaccine.

18. The agent administration device of claim 11 , wherein the device further comprises a removable lock member configured to hold the sharp assembly in the storage state when installed in the device.

19. The agent administration device of claim 11 , wherein the actuation assembly includes the guide pin, a bias member configured to assert a bias force on the guide pin, and a pivot pin pivotally retained in the housing and coupled to the guide pin.

20. The agent administration device of claim 11 , wherein the access port is in fluid communication with the delivery sharp in the storage state, administration state, and any position therebetween.

21. The agent administration device of claim 11 , wherein the stop is displaceable to a stowed position, the guide pin displacing a further amount in the single direction when the stop is displaced to the stowed position, the at least one delivery sharp retracting into the housing as the guide pin displaces the further amount.

22. The agent administration device of claim 13 , wherein the insertion angle is 5°-45°.

23. An agent administration device comprising:

a housing;

a delivery sharp assembly reciprocally displaceable along a guide of the housing;

an actuation assembly having a single bias member, the delivery sharp assembly being driven, when the single bias member is released from a storage state, from a first position in which the delivery sharp assembly is within the housing, through an intermediate positon in which a delivery sharp of the delivery sharp assembly projects a maximum distance out of the housing and into a stationary delivery position in which the delivery sharp projects a lesser distance than the maximum distance; and

an access port in fluid communication with the delivery sharp assembly.

24. The agent administration device of claim 23 , wherein the device further comprises a removable lock member configured to hold the delivery sharp assembly in the storage state when installed in the device.

25. The agent administration device of claim 23 , wherein the lesser distance corresponds to a penetration depth in a patient suitable for intradermal administration of agent.
