Abstract

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.

First claim

What is claimed is:

1. An analyte measuring system, comprising:
a mounting unit adapted for mounting on a skin of a host;
an electronics unit detachably connectable to the mounting unit, wherein the electronics unit comprises electronic circuitry encapsulated within a sensor body, and wherein the electronic circuitry is encapsulated in the sensor body by a molded water vapor permeable polymer material to provide a substantially seamless exterior with a portion of an electrode system exposed on the exterior of the substantially seamless body; and
a sensor configured for measuring a level of an analyte, the sensor comprising an in vivo portion for insertion through the skin at an exit site of the host and an ex vivo portion connected to the mounting unit, wherein the sensor is operably connected to the electronics unit when the electronics unit is detachably connected to the mounting unit, and wherein the in vivo portion comprises the electrode system.

2. The system of claim 1 , wherein the polymer material is epoxy.

3. The system of claim 1 , wherein the circuitry comprises an inductor for a voltage controlled oscillator.

4. The system of claim 1 , wherein the electronic circuitry further comprises a microprocessor, RF circuitry, an antenna and a power source encapsulated within the body.

5. The system of claim 1 , wherein at least a portion of the electronic circuitry comprises a conformal coating.

6. The system of claim 1 , wherein the mounting unit comprises an opening configured to receive the sensor electronics therein.

7. The system of claim 1 , further comprising an elastomeric sealing member configured to form a watertight seal at the portion of an electrode system exposed on the exterior of the substantially seamless body and at electrical connection areas on the ex vivo portion of the sensor.
