Analyte monitoring device and methods of use
First Claim
1. An analyte sensing assembly, comprising:
- a mounting unit configured to adhere to a skin surface;
a housing unit; and
an analyte sensor configured to couple to the housing unit, the analyte sensor including at least one electrode;
wherein the analyte sensor includes a proximal portion configured to connect with the housing unit and a distal portion that includes a portion of the at least one electrode configured to be subcutaneously positioned beneath the skin surface, wherein the portion of the at least one electrode that is configured to be subcutaneously positioned is covered with an analyte mass transport limiting layer, and wherein the analyte sensor is configured to advance through the mounting unit after the mounting unit is adhered to the skin surface, the analyte sensor is further configured to connect with the housing unit after the distal portion of the analyte sensor is positioned beneath the skin surface, and a conductive contact of the analyte sensor is configured to couple with at least one conductive contact disposed on the housing unit.

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.
