1. An analyte monitoring system, comprising:
- a proximal housing configured to be affixed to a patient'"'"'s body;
a cannula that is configured for placement through the skin of a patient'"'"'s body, that extends from the proximal housing, and that includes an inner lumen; and
one or more continuous or semi-continuous sensors placed in fluid communication with the inner lumen of the cannula such that the one or more sensors are not in direct contact with the body of the user.

Abstract
Analyte monitoring systems and methods that make interstitial fluid from a patient'"'"'s body available to one or more sensors disposed outside the patient'"'"'s body. The monitoring systems and methods may be used in conjunction with medicament dispensing systems and methods in order to provide a feedback loop for continuous sensing of analyte levels and corresponding dispensing of medicament based on sensed analyte levels. Dispensing or pumping systems or portions thereof may be used to move a patient'"'"'s interstitial fluid into communication with the one or more sensors.

21. An analyte monitoring system, comprising:
-
a cannula which has an inner lumen and which is configured to be placed through the skin into the subcutaneous space of the patient'"'"'s body; a proximal housing that may be affixed to a patient'"'"'s body which comprises a septum that is in fluid communication with an inner lumen of the cannula and that is disposed at a distal end of the cannula; a distal housing that may be detachably secured to the proximal housing and which comprises a needle configured to penetrate the septum of the proximal housing upon engagement of the housings; and one or more continuous or semi-continuous sensors placed in fluid communication with the inner lumen of the cannula such that the one or more sensors are not in direct contact with the patient'"'"'s body. - View Dependent Claims (22, 23, 24, 25)
