ANALYTE SENSORS HAVING A SIGNAL-TO-NOISE RATIO SUBSTANTIALLY UNAFFECTED BY NON-CONSTANT NOISE
First Claim
Patent Images
1. An electrochemical analyte sensor for determining a concentration of an analyte in a host, the sensor configured for insertion into a host, wherein the sensor comprises at least one electrode configured to measure an analyte concentration substantially continuously;
- and electronics configured to provide a signal measured at the electrode;
wherein the signal comprises an analyte-related component and a noise component, wherein the noise component comprises a substantially non-constant non-analyte-related component; and
wherein the sensor is configured such that the substantially non-constant non-analyte related component does not substantially contribute to the signal, after sensor break-in, for at least about one day.

Abstract
Systems and methods of use involving sensors having a signal-to-noise ratio that is substantially unaffected by non-constant noise are provided for continuous analyte measurement in a host. In some embodiments, a continuous analyte measurement system is configured to be wholly, transcutaneously, intravascularly or extracorporeally implanted.
