Abstract

Method and system for providing an integrated analyte monitoring system and on-body patch pump with multiple cannulas and a sensor combination is provided.

Claims

1. An integrated therapy management system, comprising:

a first cannula for transcutaneous placement under a skin layer of a patient at a first infusion site for a first time period;

a second cannula for transcutaneous placement under the skin layer of the patient at a second infusion site for a second time period; and

an analyte sensor configured for fluid contact with an analyte of the patient for a predetermined time period;

wherein the first cannula and the second cannula are configured to deliver a therapeutic agent to the patient during the predetermined time period.

2. The system of claim 1 further including a housing, wherein the first cannula, the second cannula and the sensor are coupled to the housing.

3. The system of claim 1 further including a housing, wherein the first cannula and the sensor are coupled to the housing.

4. The system of claim 3 wherein the second cannula is connected to the housing by an infusion tubing.

5. The system of claim 1 wherein the first infusion site and the second infusion site are separated by a predetermined distance.

6. The system of claim 1 wherein the predetermined time period includes approximately seven days.

7. The system of claim 1 further including a reservoir coupled to the first cannula and the second cannula.

8. The system of claim 1 further including a first reservoir coupled to the first cannula, and a second reservoir coupled to the second cannula.

9. The system of claim 1 wherein when the second cannula is transcutaneously positioned, the first cannula is withdrawn from the first infusion site.

10. The system of claim 1 wherein the sensor includes an analyte sensor.

11. The system of claim 1 wherein the therapeutic agent includes insulin.

12. A method, comprising:

positioning a portion of a first cannula under the skin of a patient;

positioning a portion of a sensor under the skin of the patient;

positioning a portion of a second cannula under the skin of a patient; and

withdrawing the first cannula from the patient while retaining the sensor position under the skin of the patient.

13. The method of claim 12 wherein the positioning the portion of the first cannula and the positioning the portion of the sensor are substantially simultaneously performed.

14. The method of claim 12 wherein the sensor is positioned under the skin of the patient for approximately seven days.

15. The method of claim 12 wherein the sensor includes an analyte sensor.

16. An integrated therapy management system, comprising:

an on-body micropump including;

a first cannula for transcutaneous placement under a skin layer of a patient at a first infusion site for a first time period;

a second cannula for transcutaneous placement under the skin layer of the patient at a second infusion site for a second time period;

an analyte sensor configured for fluid contact with an analyte of the patient for a predetermined time period; and

a controller in signal communication with the on-body micropump, the controller configured to transmit one or more signals to the micropump to control the delivery of a therapeutic agent to the patient using one or more of the first cannula and the second cannula.

17. The system of claim 16 wherein the micropump further includes a transmitter unit operatively coupled to the analyte sensor.

18. The system of claim 17 wherein the controller is configured to receive one or more signals associated with one or more analyte levels of the patient from the transmitter unit.

19. The system of claim 18 wherein the controller is further configured to receive one or more signals associated with the therapeutic agent delivery.

20. The system of claim 16 wherein the controller is in signal communication with the on-body micropump over a wireless communication link.
