Abstract
The present invention relates generally to systems and methods for measuring an analyte in a host and associated methods of manufacture. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host and associated methods of manufacture.
Claims21
A continuous glucose sensor for measurement of glucose in a host, the sensor comprising:
- at least one electrode comprising a conductive material;
- and
- a membrane system disposed on an electroactive portion of the electrode, wherein the membrane system comprises a smooth outer surface formed by a vapor deposition process,
- wherein, for a time period of at least about one day, the membrane system is biocompatible and is configured to provide a linear response to glucose concentrations from about 40 mg/dL to about 400 mg/dL.
1 more element
A method for manufacturing a transcutaneous glucose sensor, the method comprising the step of:
- applying a membrane system to an electroactive portion of at least one electrode, wherein the membrane system comprises a smooth outer surface formed by vapor deposition, and
- wherein, for a time period of at least about one day, the membrane system is biocompatible and is configured to provide a linear response to glucose concentrations from about 40 mg/dL to about 400 mg/dL.
