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. 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.

2. The method of claim 1 wherein the positioning the portion of the first cannula and the positioning the portion of the sensor are substantially simultaneously performed.

3. The method of claim 1 wherein the sensor is positioned under the skin of the patient for approximately seven days.

4. The method of claim 1 wherein the sensor includes an analyte sensor.
