Abstract

Embodiments of the disclosure relate to medical devices and, in particular, to devices for delivery of basal and/or bolus doses of one or more medicaments to a patient. In one embodiment, a medical device for delivering a medicament to the body of a user may include a reservoir configured to contain the medicament, a delivery mechanism for channeling the medicament from the reservoir to the user, a pumping mechanism for pumping the medicament from the reservoir, through the delivery mechanism, and to the user, wherein the medical device may be configured to deliver a dose of the medicament to the user. The medical device may also include a sensor for monitoring a parameter of the body and a display of information to alert and keep the user informed.

Claims

1. A medical device for delivering a medicament to a body of a user, comprising:

an elongate housing;

a reservoir configured to contain the medicament;

a delivery mechanism for channeling the medicament from the reservoir to the user;

a pumping mechanism for pumping the medicament from the reservoir, through the delivery mechanism, and to the user, wherein the medical device is configured to deliver a basal dose of the medicament to the user; and

a first sensor for monitoring a parameter of the body.

2. The medical device of claim 1, wherein the elongate housing includes a securing mechanism configured to secure the elongate housing to an article of clothing.

3. The medical device of claim 2, wherein the elongate housing includes dimensions allowing the housing to be disposed substantially within a pocket of the article of clothing.

4. The medical device of claim 1, wherein the reservoir is configured to contain a plurality of medicaments.

5. The medical device of claim 4, wherein the pumping mechanism is configured to deliver a first medicament of the plurality of medicaments at a first rate and to deliver a second medicament of the plurality of medicaments at a second rate, wherein the second rate is different from the first rate.

6. The medical device of claim 1, wherein the pumping mechanism is configured to selectively deliver bolus doses to the user.

7. The medical device of claim 6, wherein the housing includes an actuator configured to allow the user to instruct the medical device to deliver a bolus dose of the medicament.

8. The medical device of claim 1, wherein the elongate housing includes a graphical display screen.

9. The medical device of claim 1, wherein the first sensor is configured to continuously monitor the parameter.

10. The medical device of claim 1, further comprising a device control unit configured to receive data from the first sensor, wherein the device control unit includes a data acquisition system.

11. The medical device of claim 1, wherein the parameter is blood glucose.

12. The medical device of claim 1, wherein the first sensor includes a portion in communication with blood of the user.

13. The medical device of claim 12, wherein the portion is implanted within the body of the user.

14. The medical device of claim 13, wherein the portion is wirelessly coupled to the first sensor.

15. The medical device of claim 1, further comprising a second sensor analyzing a blood sample removed from the body for the parameter.

16. The medical device of claim 1, wherein the reservoir is selectively removable from the housing.

17. The medical device of claim 1, wherein the pumping mechanism includes a magnet and an electromagnetic coil.

18. The medical device of claim 1, wherein the housing includes electronics for controlling the first sensor and the pumping mechanism.

19. The medical device of claim 18, further comprising a handheld controller in wireless communication with the electronics.

20. The medical device of claim 19, wherein the handheld controller includes a second sensor configured to analyze a blood sample removed from the body for the parameter.

21. The medical device of claim 1, wherein the elongate housing has a length in the range of about 3.5 inches to 4.5 inches, and a width in the range of about 0.40 inches to 0.6 inches.

22. The medical device of claim 1, wherein the elongate housing includes a substantially cylindrical configuration.

23. The medical device of claim 1, wherein the elongate housing is substantially pen-shaped.

25. The pump mechanism of claim 23, wherein the first and second magnets are disposed in the first and second openings.

26. The pump mechanism of claim 25, wherein the flexible membrane is operably coupled to one of the first and second magnets.

24. A pump mechanism for delivering a medicament from a reservoir, wherein the reservoir is removably secured to a housing, the pump mechanism comprising:

a first elongate pump insert body having a first opening configured to receive a first magnet;

a second elongate pump insert body having a second opening configured to receive a second magnet;

a flexible membrane disposed in between the first and second elongate pump insert bodies; and

a plurality of electromagnetic coils.

27. The pump mechanism of claim 24, wherein the reservoir is disposed in a housing configured to be secured to an article of clothing.

28. A medical device for delivering a medicament to the body of a user, comprising:

an elongate housing;

a reservoir configured to contain the medicament;

a delivery mechanism for channeling the medicament from the reservoir to the user;

a pumping mechanism for pumping the medicament from the reservoir and through the delivery mechanism to the user, the pumping mechanism comprising;
