Abstract
Systems and methods of use for continuous analyte measurement of a host's vascular system are provided. In some embodiments, a continuous glucose measurement system includes a vascular access device, a sensor and sensor electronics, the system being configured for insertion into communication with a host's circulatory system.
Claims20
A system for detecting glucose, comprising:
- a first sensor configured to be implanted in a host, wherein the first sensor is configured to generate a first signal and a second signal, wherein the first signal is associated with glucose and wherein the second signal is associated with a reference analyte that is non-glucose;
- a second sensor configured to generate a reference signal associated with the reference analyte;
- and
- at least one processor configured to:
- determine a sensitivity associated with the first sensor using the reference signal from the second sensor and the second signal from the first sensor, and
- determine a glucose concentration using the sensitivity associated with the first sensor and the first signal from the first sensor.

A method for detecting glucose, comprising:
- providing a first sensor configured to be implanted in a host, wherein the first sensor is configured to generate a first signal and a second signal, wherein the first signal is associated with glucose and wherein the second signal is associated with a reference analyte that is non-glucose;
- providing a second sensor configured to generate a reference signal associated with the reference analyte;
- and
- providing at least one processor, the at least one processor configured to:
- determine a sensitivity associated with the first sensor using the reference signal from the second sensor and the second signal from the first sensor, and
- determine a glucose concentration using the sensitivity of the first sensor and the first signal from the first sensor.
