Transcutaneous analyte sensor
The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.
1. A continuous analyte monitoring assembly adapted to assist in determining an analyte level of a fluid, the continuous analyte monitoring assembly comprising:
a housing having a bottom, the bottom forming a recess;
electronics located within the housing, the electronics being adapted to assist in determining an analyte level of a fluid sample;
an implantable sensor comprising a sensor body and at least one electrode disposed on the sensor body, wherein the implantable sensor is adapted to move from a retracted position to an inserted position through the recess, wherein in the retracted position the implantable sensor is at least partially curved and stowed at least partially inside the housing, wherein in the retracted position the at least one electrode resides above a host's skin, wherein in the inserted position the implantable sensor extends at least partially out of the housing, wherein in the inserted position the at least one electrode is adapted to at least partially reside under the host's skin; and
a cannula being adapted to assist in placing the implantable sensor.
2. The assembly of claim 1 , wherein the electronics is a printed circuit.
3. The assembly of claim 1 , further including a removable adhesive liner, the adhesive liner adapted to attach to skin.
4. The assembly of claim 1 , wherein the housing includes a disposable housing and a reusable housing, the reusable housing being adapted to contain the electronics.
5. The assembly of claim 4 , wherein the disposable housing includes the implantable sensor, the cannula and an adhesive liner.
6. The assembly of claim 1 , wherein the implantable sensor is a wire that includes a reagent.
7. The assembly of claim 1 , wherein the implantable sensor is an electrochemical sensor.
