First Claim
Patent Images
1. A transcutaneous system for measuring an analyte concentration in a host, the system comprising:
- a sensor adapted for transcutaneous placement through a skin of a host, the sensor comprising a first end and a second end; and
an applicator comprising a needle configured for inserting the sensor into the skin of the host;
wherein a diameter of the first end of the sensor is substantially the same as that of a diameter of the second end of the sensor, such that the needle is capable of inserting the first end of sensor into the host, sliding back over the second end of the sensor, and releasing the sensor from the needle.

7. A method for inserting a transcutaneous analyte sensor into a host using an applicator, the method comprising the steps of:
-
pushing on a first component of an applicator for inserting a transcutaneous analyte sensor into a host, so as to insert the needle and the sensor into the skin of the host; and
pulling on a second component of the applicator so as to retract the needle from the skin of the host, while leaving the sensor in the host;
whereinthe first component and the second component of the applicator are configured to interact so as to enable insertion of the sensor and retraction of the needle using a single continuous motion provided by a user. - View Dependent Claims (8, 9)
