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.

Claims (15)

1. A system for manufacturing a continuous glucose sensor, comprising:

a plurality of stations configured to serially deposit a plurality of membrane layers to form a membrane surrounding an electroactive surface of a substantially cylindrically-shaped conductive body, wherein the membrane comprises an enzyme layer comprising an enzyme configured to catalyze reaction of glucose and a resistance layer configured to control a flux of glucose to the electroactive surface; and

an automated or semi-automated mechanism configured to continuously move the substantially cylindrically-shaped conductive body through the plurality of stations.

2. The system of claim 1 , further comprising a station for cutting the substantially cylindrically-shaped conductive body to form a plurality of continuous glucose sensors.

3. The system of claim 1 , further comprising a station for curing the membrane.

4. The system of claim 1 , wherein the plurality of stations comprises a station for depositing a coating material to form the enzyme layer.

5. The system of claim 1 , wherein the plurality of stations comprises a station for depositing a coating material to form a layer configured to block or reduce passage of one or more interferents.

6. The system of claim 1 , wherein the plurality of stations comprises a station for depositing a coating material to form the resistance layer.

7. The system for claim 1 , wherein the substantially cylindrically-shaped conductive body comprises at least one material selected from the group consisting of: platinum, platinum-iridium, palladium, graphite, gold, carbon, conductive polymer, and alloys or combinations thereof.

8. The system of claim 1 , wherein the substantially cylindrically-shaped conductive body comprises a plated wire.

9. The system of claim 1 , wherein the automated or semi-automated mechanism comprises a reel-to-reel mechanism.

10. The system of claim 1 , wherein the automated or semi-automated mechanism comprises a robot driven mechanism.

11. The system of claim 1 , wherein the automated or semi-automated mechanism is configured to continuously move a plurality of substantially cylindrically-shaped conductive bodies.

12. The system of claim 1 , wherein the continuous glucose sensor is configured for implantation in a host and is configured to provide continuous measurement of glucose concentration in the host.

13. The system of claim 1 , wherein the substantially cylindrically-shaped conductive body comprises a wire.
