Analyte Monitoring Device and Methods of Use
First Claim
1. A system, comprising:
- an in vivo glucose sensor that continuously monitors glucose concentration and generates signals associated with the glucose concentration;
a processor that processes the generated signals; and
a user interface that outputs information associated with the continuously monitored glucose concentration;
wherein the signals generated by the in vivo glucose sensor have a level of accuracy that increases on subsequent days during a sensor session of at least 3 days from sensor initialization.

Abstract
An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte. The analyte monitor may also be part of a drug delivery system to alter the level of the analyte based on the data obtained using the sensor.
