Abstract

A drug delivery device includes a housing having an interior space, a needle having retracted and deployed states, an injector to move the needle between retracted and deployed states, and a reservoir disposed within the interior space, the reservoir configured to receive a volume of a drug and to be in fluid communication with the needle. The drug delivery device also includes a controller coupled to the injector and the reservoir, and configured to actuate the injector to move the needle from the retracted state to the deployed state only once, and to actuate the reservoir to deliver the volume of the drug to the patient as a single bolus after a preselected time period has elapsed, the controller disposed within the interior space and configured prior to being disposed within the interior space. The delivery device is wearable, disposable, and single-use.

Claims

1. A drug delivery device comprising:

a disposable housing having an interior surface defining an interior space, and an exterior surface;

a needle having a retracted state wherein the needle is withdrawn inside of the interior space and a deployed state wherein a pointed end of the needle projects beyond the exterior surface of the housing;

an injector coupled to the needle to move the needle between the retracted and deployed states;

a reservoir disposed within the interior space, the reservoir configured to receive a volume of a drug and to be in fluid communication with the needle; and

a controller coupled to the injector and the reservoir, the controller being configured to actuate the injector to move the needle from the retracted state to the deployed state only once, and to actuate the reservoir to deliver the volume of the drug to the patient as a single bolus after a preselected time period has elapsed, the controller disposed within the interior space and configured prior to being disposed within the interior space,

wherein the delivery device is wearable, disposable, and single-use.

2. The delivery device according to claim 1, further comprising a volume of an erythropoiesis stimulating agent disposed in the reservoir.

3. The delivery device according to claim 1, further comprising a volume of a granulocyte colony-stimulating factor disposed in the reservoir.

4. The delivery device according to claim 1, further comprising a volume of a TNF blocker disposed in the reservoir.

5. The delivery device according to claim 1, further comprising a volume of a pegylated granulocyte colony-stimulating factor disposed in the reservoir.

6. The delivery device according to claim 1, further comprising a volume of interleukin-receptor specific antibody disposed in the reservoir.

7. The delivery device according to claim 1, further comprising a volume of IGF-receptor specific antibody disposed in the reservoir.

8. The delivery device according to claim 1, further comprising a volume of TGF-specific antibody disposed in the reservoir.

9. The delivery device according to claim 1, wherein the controller determines that the preselected time period has elapsed.

10. The delivery device according to claim 9, wherein the controller determines that at least a 24-hour period has elapsed after actuation of an input device.

11. The delivery device according to claim 1, wherein the controller is configured to actuate the reservoir to deliver the volume of the drug to the patient as a single bolus in less than thirty minutes.

12. The delivery device according to claim 11, wherein the controller is configured to actuate the reservoir to deliver the volume of the drug to the patient as a single bolus in less than six seconds.

13. The delivery device according to claim 1, wherein the controller is configured to actuate the injector to move the needle from the deployed state to the retracted state only once.

14. The delivery device according to claim 1, comprising an input device coupled to the controller, the controller responsive to actuation of the input device to initiate action of the controller.

15. The delivery device according to claim 1, wherein the controller comprises a microprocessor programmed to actuate the injector and to actuate the reservoir.

16. The delivery device according to claim 1, further comprising a pump, wherein the controller actuates the pump to move the volume of drug from the reservoir to the needle.

17. The delivery device according to claim 16, further comprising a pinch valve disposed between the pump and the needle, wherein the controller opens the pinch valve prior to actuating the pump.

18. The delivery device according to claim 1, wherein the interior space is a sealed space.

19. The delivery device according to claim 1, further comprising an adhesive adapted to releasably secure the housing to skin during a single application, the adhesive disposed on a portion of the exterior surface and covered with a removable, disposable sheet prior to application of the housing to the skin of a patient.

20. The delivery device according to claim 1, comprising a fill port in fluid communication with the reservoir, the fill port having an inlet disposed on the exterior surface of the housing.

21. A kit comprising a delivery device according to claim 1, in combination with a syringe.

22. A method of operation of a wearable, disposable, single-use drug delivery device, the method comprising:

automatically injecting a pointed end of a needle from an interior space defined in a housing of the delivery device into the patient to define an injection site only once according to a controller contained within the interior space; and

automatically actuating a reservoir to deliver a volume of a drug to the patient through the injection site as a single bolus after a preselected time period has elapsed according to the controller contained within the interior space.

23. The method according to claim 22, wherein the drug comprises an erythropoiesis stimulating agent.

24. The method according to claim 22, wherein the drug comprises a granulocyte colony-stimulating factor.

25. The method according to claim 22, wherein the drug comprises a TNF blocker.

26. The method according to claim 22, wherein the drug comprises a pegylated granulocyte colony-stimulating factor.

27. The method according to claim 22, wherein the drug comprises interleukin-receptor specific antibody.

28. The method according to claim 22, wherein the drug comprises IGF-receptor specific antibody.

29. The method according to claim 22, wherein the drug comprises TGF-specific antibody.

30. The method according to claim 22, further comprising automatically determining that the preselected time period has elapsed according to the controller contained within the interior space, the controller being configured to determine the preselected time period before the controller is disposed in the interior space.

31. The method according to claim 30, wherein the preselected time period is at least a 24-hour period.

32. The method according to claim 22, comprising automatically retracting the pointed end of the needle into the interior space only once according to the configuration of the controller contained within the interior space.
