Analyte monitoring device and methods of use
First Claim
1. An insulin delivery system, comprising:
- an insulin administration system;
a glucose sensor, wherein a portion of the glucose sensor is positionable beneath a skin surface of an individual;
a data storage device to store glucose related information obtained by the glucose sensor; and
a controller to analyze the stored glucose related information to predict a future glucose-related event so that insulin may be administered by the insulin administration system according to at least in part the analysis;
wherein the controller is trainable such that when an episode of glucose related event is detected, the controller is configured to analyze the stored glucose related information to determine a pattern based on the analysis of the stored glucose related information, and to compare the determined pattern to a known pattern to predict the future glucose related event.

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.
